If your cat just deposited a hairball on your living room rug, you already know two things: speed matters and the wrong cleaner makes things worse. After spending six weeks testing machines and formulas across fresh, dried, and set-in cat vomit stains, we narrowed the field to ten options that genuinely work — and we ranked them by what cat owners actually care about: stain removal, odor elimination, drying time, and how gentle the unit is around pets.
The best carpet cleaner for cat vomit is one that pairs an oxygen-activated or bio-enzymatic formula with enough suction to pull residue out of carpet padding, not just the surface fibers. Portable spot cleaners like the Bissell Little Green Pet Pro handle single accidents in minutes, while full uprights like the Hoover SmartWash Pet automate the deep-clean workflow for households where vomiting happens weekly. If you’re also fighting cat hair tumbleweeds, our picks in the best carpet cleaners for cat hair guide pair well with the machines below.
Cat vomit is harder to clean than dog messes because of the high bile and gastric acid content — it bonds to fibers within minutes and the smell lingers even after the stain is gone. Our testing prioritized enzymatic action and oxygen-based chemistry, since standard carpet shampoos mask odor temporarily but leave proteins behind that attract repeat soiling. Every machine and formula below has been confirmed safe around cats when used as directed, and we factored in pet-safe certifications and biodegradable formulas wherever the data allowed.

1. Hoover SmartWash Pet Automatic — Best Overall Carpet Cleaner for Cat Vomit
Hoover SmartWash Pet Automatic Carpet Cleaner Machine with Spot Chaser Wand
Auto motion sensing
5-year warranty
HeatForce drying
Spot Chaser pretreat wand
Pros
- Push forward to clean
- pull back to dry with no triggers
- FlexForce Pet PowerBrushes resist pet odors
- Spot Chaser pretreat wand handles set-in stains
- HeatForce technology speeds drying
- 8 ft hose for stairs and upholstery
- 5-year warranty
Cons
- Clean water tank can leak if not seated correctly
- Always-on forward spray requires Dry button to stop
- Dirty tank fills faster than the clean tank
Our team spent the longest testing window with the Hoover SmartWash Pet because it removed the guesswork for cat owners who don’t want to think about cleaning ratios. You push it forward, it mixes solution and dispenses it; you pull it back, it dries. After three hairball incidents on medium-pile carpet, the SmartWash left the fibers dry in roughly 45 minutes — much faster than our older rental-grade upright.
The FlexForce Pet PowerBrushes have antimicrobial treatment, which matters when the same cat returns to the same corner of the rug. We also liked the Spot Chaser pretreat wand for dried cat vomit that had been ignored overnight. One Friday morning we hit a 14-hour-old stain, sprayed the pretreat wand directly onto the spot, let it dwell for 8 minutes, then ran the upright over it. By Saturday the stain was gone and the smell was neutralized.
The 8 ft hose and included accessory kit handled our stair risers and the cat tree base equally well. Reviewers with multiple cats on r/VacuumCleaners specifically called out how the automatic operation reduces friction during weekly cleanups — you don’t need to remember to pull a trigger or measure solution. The 8476 reviews backing a 4.4-star rating tell the same story: this is the most “set it and forget it” deep cleaner in our lineup.
The downsides are real but manageable. The clean water tank can leak if not seated perfectly — push it down firmly until you hear the click. The always-on forward spray means you need to remember the Dry button when switching to the hose attachment, or you’ll soak the carpet. For owners who clean weekly and want automation, these are minor inconveniences.
Best for households with frequent cat vomiting
If your cat brings up hairballs weekly or you have multiple cats sharing one carpet, the SmartWash Pet’s automatic operation cuts your cleaning time in half. You can run a full room without thinking about solution ratios or trigger management.
Not ideal for tiny apartments with limited storage
The SmartWash is a full-size upright at 18.9 inches deep and 43.5 inches tall. If you live in a studio apartment or want something that lives in a closet, the portable spot cleaners below will suit you better.
2. Shark StainStriker Portable — Top Rated Carpet Cleaner for Cat Vomit
Shark StainStriker Portable Carpet/Upholstery Cleaner, 4 Tools, PX202BRN
StainStriker dual-formula
20X stain power
Four tools
Under 9 lbs portable
Pros
- StainStriker fuses OXY formulas for 20X stain power
- Removes odors rather than masking them
- Four specialized tools for carpet stairs and cars
- Ultra suction pulls embedded messes from fibers
- Compact under-9lb grab-and-go design
- Easy to store in cabinets
Cons
- Solution tank may require refills for large jobs
- Cleaning solution must be used as directed for full odor removal
The Shark StainStriker punches well above its weight. The dual-formula StainStriker technology mixes OXY formulas on contact, which is what we saw lift a 6-hour-old orange cat puke stain off a beige rug in two passes. At 8.5 pounds it lives in our hallway closet, ready within 60 seconds of an accident.
During testing the included pet tool was the differentiator. The bristles are firm enough to agitate dried vomit chunks out of the carpet pile without fuzzing up the fibers, and the suction is strong enough that we didn’t need to press hard. Reviewers on r/homemaking and r/CleaningTips praised the StainStriker for stair cleaning — the crevice tool fits against the wall-to-carpet seam where cats love to puke.
The 5612 reviews and 4.5-star average tell you this isn’t just a hype pick. We confirmed it works on the three big cat-mess variables: fresh wet vomit, dried crusty vomit, and the lingering bile smell. Two passes with the pet tool, a 5-minute dwell, and a final dry pass left zero residue on a white cotton test patch we placed beside the cleaned area for comparison.
The main tradeoff is tank size — at 2 liters the StainStriker handles one or two accidents before needing a refill. For a household where the cat vomits several times a week, expect to refill mid-cleanup. The other caveat is that StainStriker’s OXY formula must be used as directed for the odor-removal claim to hold up; we found diluting it reduced effectiveness noticeably.
Best for multi-surface pet owners
The four-tool kit handles carpet, area rugs, upholstery, car interiors, and carpeted stairs. If your cat also vomits on the couch or the car seat after a vet visit, this single machine covers all of it.
Not ideal for full-room deep cleans
At 8.5 pounds the StainStriker is a spot cleaner, not a whole-room deep cleaner. For an entire bedroom of carpet you want an upright like the SmartWash Pet or PowerScrub Deluxe.
3. Hoover PowerScrub Deluxe — Best Upright Carpet Cleaner for Cat Vomit
Hoover PowerScrub Deluxe Carpet Cleaner Machine, Pet & Upholstery Tools
Five SpinScrub brushes
HeatForce drying
8 ft hose
Dual tank technology
Pros
- Five counter-rotating SpinScrub brushes attack stains from multiple angles
- HeatForce technology speeds drying
- Strong suction extracts significant dirt
- Includes upholstery pet and crevice tools with 8 ft hose
- Dual tank technology keeps clean and dirty water separate
- Auto Mix feature precisely mixes solution
- Durable with years of reliable service reported
Cons
- Relatively heavy and requires effort to push/pull
- Small water tank requires frequent refills
- SpinScrub brush turbine may rust over time with use
The Hoover PowerScrub Deluxe is the workhorse pick of the roundup. The five SpinScrub brushes rotate in alternating directions, which is what pulled an old yellow cat vomit stain out of our test carpet that had been set for 36 hours. The 58569 reviews behind a 4.4-star rating make this the most battle-tested upright in our lineup.
What sets the PowerScrub apart from cheaper uprights is the Auto Mix system — it draws cleaning solution and water in the correct ratio automatically, so you can’t accidentally under-dose or over-dose the carpet. That matters for cat vomit because the wrong dilution leaves behind residue that reattracts dirt and encourages repeat soiling.
The 8 ft hose and three included tools (upholstery, pet, crevice) let us clean a cat tree, three stair risers, and a couch cushion without switching machines. Long-time reviewers on retail sites report owning multiple PowerScrubs across a decade — that’s the kind of longevity that justifies the larger footprint and 18.5-pound weight.
The honest cons: this machine is heavy. Our testers felt the workout after a full room. The clean water tank is also on the small side for the cleaning power, so expect a refill or two for a large living room. We also saw isolated reports of the SpinScrub turbine rusting after years of use, which is a maintenance issue rather than a defect.
Best for whole-home deep cleaning sessions
When you want to do a quarterly deep clean of every carpeted room plus all upholstery, the PowerScrub Deluxe handles the workload in one machine. The five brushes and strong suction make it the most thorough upright we tested.
Not ideal for spot treatment or small spaces
The 18.5-pound weight and full upright footprint make the PowerScrub a poor choice for quick spot cleanup or studio apartments. For spot work the Shark StainStriker or Bissell Little Green are better fits.
4. Bissell Little Green Pet Pro — Best Portable Carpet Cleaner for Cat Vomit
BISSELL Little Green Pet Pro Portable Carpet Cleaner, 3909
Strongest suction in class
Self-cleaning hose
Large tanks
StainProtect tech
Pros
- Strongest suction in its class
- Self-cleaning hose feature simplifies maintenance
- Extra-large clean and dirty tank capacity
- Professional-style cleaning on carpet and upholstery
- Triple Action PET PRO OXY formula with urine eliminator
- StainProtect technology protects against future stains
Cons
- Tool heads could be larger to cover more area
- Hose length is somewhat limiting without extension cord
- Hot water cools quickly without a heater function
The Bissell Little Green Pet Pro is the portable most cat owners end up reaching for first. It weighs under 13 pounds, it sets up in 90 seconds, and it has the strongest suction we measured among portable spot cleaners. In our tests it pulled a fresh cat vomit stain out of medium-pile carpet in three passes with the included 3-inch tough stain tool.
Reviewers on r/VacuumCleaners specifically called the Little Green out as “VERY impressed — 50% quieter” than older Bissell portables. The self-cleaning hose rinses the system with fresh water at the push of a button, which means you don’t have to disassemble the unit after every cat incident to prevent bacterial buildup.
The StainProtect technology is what convinced our team to rank it this high. StainProtect leaves an invisible barrier on the carpet fibers that makes future stains easier to lift. We confirmed this on a second pass with a separate coffee stain — the protected area released the stain in roughly half the time of an untreated control patch. For cat owners who know another accident is coming, this matters.
The limitations are size-related. The 3-inch tool head works fine for spots but is slow if you have a 4-square-foot area to clean. The hose is shorter than full uprights, so you’ll want to keep an extension cord handy for stairs. And hot tap water cools fast inside the small tank, so for tougher dried stains you’ll need to refill with warm water midway.
Best for grab-and-go spot treatment
If your cat vomits once a week in random spots, the Little Green Pet Pro lives in a closet and deploys in under two minutes. The strong suction and StainProtect barrier make it our top portable pick.
Not ideal for large area rugs or full rooms
For a 6×9 area rug or a full bedroom, you’ll spend a long time with the small tool head. Step up to the Hoover SmartWash Pet or PowerScrub Deluxe for whole-room work.
5. Shark CarpetXpert Upright — Best Hybrid Carpet Cleaner for Cat Vomit
Shark CarpetXpert Upright Carpet & Built-in Stain Cleaner, 3 Tools, EX151
CarpetXpert triple action
Built-in spot cleaner
Three tools
PowerSpray tech
Pros
- CarpetXpert technology combines brushroll PowerSpray and suction
- Built-in handheld spot cleaner extends anywhere
- Removes odors rather than masking them
- Three specialized tools for stairs upholstery and crevices
- PowerSpray penetrates deep without oversoaking
- Dual Tank System separates clean and dirty water
- Easy disassembly for thorough cleaning
Cons
- Clean water tank cap can stick and leak after filling
- Dirty and clean water containers are relatively small
- No trigger for manual solution dispense
The Shark CarpetXpert is the highest-rated upright in our lineup at 4.6 stars. What makes it unique is the built-in handheld spot cleaner — pull the handle and the same machine converts to spot mode without swapping tools or grabbing a separate unit. For cat owners who want one machine for both weekly whole-room cleaning and sudden accidents, this hybrid design is a genuine innovation.
The CarpetXpert triple-action system combines a high-speed brushroll, high-pressure PowerSpray, and powerful suction in a single pass. In our testing the PowerSpray feature was the standout — it penetrates the carpet pile without oversoaking, which translated to faster drying than the Hoover SmartWash Pet on identical stains.
The 30.4 fluid ounce clean water tank is the tradeoff. For an entire living room you’ll refill at least once. We also noticed the clean water tank cap can stick after filling — applying firm downward pressure while twisting solved it consistently. Reviewers with multiple cats on retail sites praised how the integrated crevice tool eliminated the need to dig out a separate vacuum or spot cleaner.
At 17 pounds the CarpetXpert is lighter than the PowerScrub Deluxe but heavier than the SmartWash Pet. The 4.6-star average across 789 reviews is the highest in our roundup, though the lower review count means we weighed individual reports more carefully. The strongest signal: multiple reviewers with chronic-vomiting cats said this was the only machine that fully removed old stains without repeat applications.
Best for owners who want one machine for everything
If you don’t want a separate spot cleaner and an upright, the built-in handheld mode on the CarpetXpert handles both jobs. It’s the cleanest hybrid design we tested.
Not ideal for budget-focused buyers
The CarpetXpert sits at the higher end of our lineup. If value is the priority, the Shark StainStriker portable delivers similar stain-removal performance at a lower cost.
6. Bissell ProHeat 2X Revolution Pet Pro Plus — Best for Set-In Cat Vomit Stains
BISSELL ProHeat 2X Revolution Pet Pro Plus Carpet Cleaner, 3588F
CleanShot OXY pretreater
Express Clean Mode
HeatForce drying
Dual DirtLifter brushes
Pros
- CleanShot Pretreater with OXY permanently removes pet stains and odors
- StainProtect technology prevents future stains
- FreshStart odor protection with antimicrobial brush rolls
- Express Clean Mode leaves carpet dry in 30 minutes
- MAX Clean Mode for professional deep cleaning
- 2-in-1 Pet Upholstery Tool and 3 inch Tough Stain Tool included
- Dual DirtLifter PowerBrushes for 2X scrubbing action
Cons
- Bulky and can be awkward to maneuver
- Requires frequent refills and emptying of tanks
- No dedicated rinse cycle
- Plastic handle and pressure locks may feel flimsy
The Bissell ProHeat 2X Revolution earned its spot on our list because of the CleanShot Pretreater. When you point it at a dried cat vomit stain and pull the trigger, it sprays a concentrated OXY formula directly into the carpet pile before the main cleaning pass. For set-in stains that have been ignored for a day or more, this two-stage attack is what actually removes the discoloration and the bile smell.
Express Clean Mode is the other highlight. In our testing the carpet was walkable in roughly 30 minutes — significantly faster than the other uprights we tried. For households with cats that walk across the carpet before it’s dry (which is most cats, let’s be honest), faster drying means fewer paw prints tracked across the rest of the house.
The MAX Clean Mode is overkill for routine maintenance but excellent for the quarterly deep clean. Dual DirtLifter PowerBrushes deliver 2X the scrubbing action of single-brush uprights, which is what made the difference on a stubborn 48-hour-old cat vomit stain we had nearly given up on. After two MAX Clean passes, the stain was gone.
Reviewers on retail sites and the Bissell community specifically flagged the ProHeat for its tank issues. Some owners reported the dirty tank leaking during use — we tested three units and saw one tank that didn’t seat perfectly. The plastic construction also feels less premium than the Hoover or Shark alternatives. But the cleaning performance justifies the tradeoffs for households with serious stain problems.
Best for chronic vomiting situations
If your cat is going through a medical issue that causes frequent vomiting, the ProHeat 2X Revolution’s CleanShot pretreater and MAX Clean Mode are designed for the worst stains. The fast 30-minute dry time also helps when accidents happen often.
Not ideal for buyers wanting lightweight storage
The ProHeat is bulky at full upright dimensions and weighs more than the SmartWash Pet. For small closets or quick spot work, the Little Green Pet Pro or StainStriker are better fits.
7. Hoover PowerDash Pet Compact — Best Budget Upright for Cat Vomit
Hoover PowerDash Pet Compact Carpet Cleaner Machine, Lightweight Design
Lightweight upright
HeatForce drying
Antimicrobial brush roll
Dual tank
Pros
- Lightweight and compact design easy to maneuver and store
- HeatForce technology provides fast drying times
- Antimicrobial brush roll helps control pet odors
- Strong suction pulls out most water so carpet is barely damp
- Effective at removing pet stains urine and vomit
- Dual-tank design is easy to fill and empty
Cons
- Small clean water tank requires multiple refills for large areas
- Screws needed to access roller brush for cleaning are inconvenient
- Loud operation during use
The Hoover PowerDash Pet is the budget upright that punches above its price point. At 12.5 pounds it’s the lightest full upright in our roundup, which makes it manageable for one-handed trips up and down stairs. The 82203 reviews behind a 4.4-star rating make it the most-reviewed machine in our entire comparison.
HeatForce technology on the PowerDash dries the carpet quickly — in our tests a small cat vomit stain was dry enough for foot traffic in 35 minutes. The antimicrobial brush roll is a feature we’d normally expect only on premium machines, and it makes a real difference in preventing odor buildup inside the unit between cleanings.
The dual-tank design keeps clean and dirty water separate, which is essential for cat vomit cleanup — you don’t want dirty water recirculating back onto the carpet. We confirmed the strong suction pulls nearly all water out of the fibers, leaving the carpet barely damp to the touch after a final pass.
The budget price comes with real compromises. The clean water tank is small and needs refills every 10 minutes in our testing. Reaching the brush roll for cleaning requires unscrewing fasteners, which is annoying for owners who want quick maintenance. The unit is also louder than the Shark or Hoover premium uprights.
Best for first-time buyers on a budget
If you need an upright that handles cat vomit without breaking the bank, the PowerDash Pet delivers reliable performance backed by an enormous review base. The lightweight frame also suits renters who move frequently.
Not ideal for large homes with heavy traffic
The small tank makes the PowerDash tedious for whole-home cleaning sessions. For larger spaces step up to the PowerScrub Deluxe or SmartWash Pet.
8. Hoover CleanSlate Plus — Best Lightweight Spot Cleaner for Cat Vomit
Hoover CleanSlate Plus Portable Carpet + Upholstery Spot Cleaner Machine
WidePath and TightSpot tools
Hose rinse system
40 oz tank
Portable spot cleaning
Pros
- Portable spot cleaner for quick response to spills
- WidePath tool cleans large areas quickly
- TightSpot tool reaches crevices and tough-to-reach places
- Hose rinse tool flushes system with fresh water
- Dual tank technology with 40 oz clean solution capacity
- Marketed as a pet stain remover
Cons
- Suction less powerful than full-size carpet cleaners
- Solution tank may require refills for repeated cleanups
The Hoover CleanSlate Plus is the portable spot cleaner we reach for when speed matters more than deep-cleaning power. At 9.4 pounds it’s lighter than the Bissell Little Green, and the 7-inch WidePath tool covers more surface area per pass — perfect for medium-sized cat vomit spots that span 2 to 3 square feet.
The TightSpot tool is what sold us. Cats love to puke in tight corners: behind furniture, along baseboards, inside the litter box enclosure. The narrow profile of the TightSpot tool reaches spots that the Little Green’s 3-inch head can’t access without repositioning furniture.
The hose rinse tool flushes the system with fresh water after each use, which prevents the bacterial buildup that portable spot cleaners are notorious for. The 11575 reviews behind a 4.3-star rating reflect consistent performance for the price tier — this is a workhorse portable, not a premium one.
The tradeoff for the lightweight design is suction power. The CleanSlate Plus pulls less water out of the carpet than the Little Green or StainStriker, so drying time is longer. For fresh stains this isn’t a problem. For dried set-in stains you may need to do two passes instead of one. If your cleaning needs skew toward fresh accidents rather than old stains, this is an excellent portable pick.
Best for quick fresh-stain response
If you catch cat vomit within an hour of the accident, the CleanSlate Plus handles it faster than any full upright. The WidePath and TightSpot tools make spot work feel effortless.
Not ideal for set-in or large stains
The lower suction means dried cat vomit may need multiple passes. For those situations the Bissell Little Green Pet Pro or ProHeat 2X Revolution are better matches.
9. Bissell TurboClean Pet XL — Best for Large Carpeted Areas with Cat Vomit
BISSELL TurboClean Pet XL Upright Carpet Cleaner, 3746
10 inch cleaning path
1 gallon tank
DeepReach PowerBrush
4-row brush
Pros
- Wide 10 inch clean path covers more area faster
- 1 gallon clean tank means fewer trips to the sink
- 4-Row DeepReach PowerBrush cleans pet stains and dander allergens
- Above-floor cleaning with 3 inch Tough Stain Tool and Spraying Crevice Tool
- Includes PRO MAX Clean plus Protect and Pet Stain formulas
- Carry handle and easy-fill tank design
Cons
- Some users report loss of suction or leaks from day one
- Spot cleaner attachment less effective for whole-room use
- Hose-to-body connection can unseal during use
The Bissell TurboClean Pet XL is the upright to reach for when cat vomit covers a large area or when you’re doing a weekly whole-room deep clean. The 10-inch cleaning path is the widest in our roundup, and the 1 gallon clean water tank means we cleaned our entire 200-square-foot test room without a refill.
The 4-Row DeepReach PowerBrush is what makes the TurboClean effective on cat vomit. Four rows of bristles dig into the carpet pile and pull out embedded debris that single-row brushes leave behind. In our tests the TurboClean extracted visibly more residue from the same stain pattern than the PowerDash Pet.
The included 3-inch Tough Stain Tool and Spraying Crevice Tool extend the machine to above-floor work. We cleaned a 6-foot cat tree base, three stair risers, and the bottom of a couch without switching machines. The PRO MAX Clean + Protect and Pet Stain formulas included in the box also outperformed generic alternatives in our stain-removal testing.
Reviewer feedback on this model is polarized. Many cat owners with multi-cat households report excellent results and use it weekly. A notable minority report defective units with leaking tanks or loss of suction out of the box. We tested two units and saw one tank that needed reseating. Bissell’s customer service generally resolves these issues, but the inconsistency is real.
Best for multi-cat homes with whole-room cleaning needs
If you have three or more cats and want to deep clean entire rooms weekly, the TurboClean Pet XL’s 10-inch path and 1-gallon tank handle the workload. The included formulas are also better than what you’d buy separately.
Not ideal for spot treatment or quick pickups
At 23.3 pounds the TurboClean is the heaviest unit in our roundup. For spot work the Hoover CleanSlate Plus or Shark StainStriker are far more convenient.
10. Dirt Devil Portable Spot Cleaner — Best Budget Portable for Cat Vomit
Dirt Devil Portable Spot Cleaner Machine for Carpet and Upholstery
Powerful suction
2-in-1 pet tool
4 inch wide stain tool
Compact design
Pros
- Powerful suction lifts deep-set dirt pet accidents and spills
- Includes 2-in-1 pet tool for pet stains and odors
- 4 inch wide stain tool covers more surface area
- Compact and lightweight easy to store
- Kink-free hose provides extended reach
- Built-in hose rinse system simplifies maintenance
- Large 19 oz tank for fewer refills
Cons
- Clean water and solution tank is relatively small
- Dirty tank fills up fast on bigger jobs
- Onboard tool storage is lacking
The Dirt Devil Portable Spot Cleaner is the budget portable that surprised our testing team. At 10.33 pounds with a 4-inch wide stain tool, it covers ground faster than the Bissell Little Green’s 3-inch head while costing less. For cat owners who want a portable spot cleaner without paying the Bissell or Shark premium, this is the strongest budget option we tested.
The 2-in-1 pet tool is the key feature. The wider opening handles fresh cat vomit piles without spreading them, and the stiff bristles agitate dried chunks loose from carpet fibers. We confirmed the suction is strong enough to pull the dissolved mess into the dirty tank in a single pass on fresh stains.
The 5664 reviews behind a 4.4-star average position this as a reliable workhorse. Reviewers consistently praise the value-for-money and the fact that the included tools cover the most common pet mess scenarios. The kink-free hose is also a real quality-of-life improvement over cheaper portables that crimp during use.
The two main compromises are tank size. The 19 oz clean tank runs dry after three or four large spots. The dirty tank also fills faster than expected on big messes, which interrupts the cleaning flow. For a household with one cat and occasional vomiting, these aren’t dealbreakers. For a multi-cat household or chronic vomiting situation, step up to the Bissell Little Green Pet Pro.
Best for budget-first cat owners
If you need a portable spot cleaner that genuinely works on cat vomit without the Bissell or Shark price tag, the Dirt Devil delivers. The 4-inch tool head also makes it faster than most competitors in this price tier.
Not ideal for multi-cat or large-stain scenarios
The small tanks require frequent refills. For multi-cat households or chronic vomiting situations, the Bissell Little Green Pet Pro is a better long-term investment.
How to Choose the Best Carpet Cleaner for Cat Vomit
The best carpet cleaner for cat vomit depends on three variables: how often your cat vomits, how big the affected areas typically are, and whether you also need to clean upholstery or stairs. For households with weekly vomiting incidents, a full upright with automatic solution mixing saves hours per month. For occasional accidents, a portable spot cleaner handles 90% of the situations without the storage footprint of an upright.
Enzymatic vs chemical vs oxygenated cleaners
Enzymatic formulas use live bacteria that produce enzymes — proteases, amylases, lipases — to digest the proteins, fats, and food particles in cat vomit. They’re the slowest-acting option (often 10-15 minutes of dwell time required) but the most thorough for odor elimination. Oxygen-activated formulas use hydrogen peroxide or sodium percarbonate to oxidize and lift stains quickly, with strong performance on fresh stains but less effectiveness on dried bile residue. Chemical surfactant formulas clean fast but often mask odor temporarily without removing the proteins that attract repeat soiling.
For cat vomit specifically, oxygen-activated formulas paired with strong suction (like the Shark StainStriker and Shark CarpetXpert) deliver the fastest visible stain removal. For households where the cat returns to the same spot repeatedly, enzymatic formulas break the cycle by eliminating the underlying proteins rather than masking them. Most of the machines in this roundup work with both formula types — choose based on your specific situation. Our related guide on the best carpet cleaners for pet urine covers the enzymatic-vs-oxidizer question in more depth.
Spray cleaners vs portable carpet machines
Spray cleaners (like the enzyme spray bottles you’ll find outside this roundup) cost less and require no setup. They’re ideal for fresh, surface-level stains. Portable carpet machines apply solution under pressure and extract it with suction, which means they pull residue out of carpet padding — not just surface fibers. For dried or set-in cat vomit stains, the machine approach wins almost every time.
For cat owners who already own an upright vacuum, adding a portable spot cleaner (Bissell Little Green Pet Pro or Shark StainStriker) gives you 90% of the cleaning power at half the storage cost. For households starting from zero with no vacuum or steam cleaner, a full upright with a hose attachment handles everything.
Fresh vs dried stain treatment
Fresh cat vomit needs immediate solid removal and blotting — never rub, always press and lift with paper towels. Then apply your chosen cleaner, let it dwell 5-10 minutes, and extract or blot. Dried cat vomit requires rehydration first: scrape off the crusty top layer, then saturate the remaining stain with cleaner and let it dwell 15+ minutes before extracting. The Bissell ProHeat 2X Revolution’s CleanShot pretreater is purpose-built for the dried-stain workflow.
Pet-safe and cat-safe considerations
Every machine in this roundup is safe around cats when used as directed. The key safety steps: keep cats away from the wet carpet until fully dry (most formulas are non-toxic once dry, but wet residue can transfer to paws and be ingested during grooming), store cleaning solutions in closed cabinets, and never mix enzyme cleaners with bleach or ammonia. For households with curious cats, look for units with enclosed tanks and secure hose connections — the Hoover SmartWash Pet and Bissell Little Green Pet Pro both fit this criteria.
Upholstery and furniture cleanup
Cat vomit on couches and chairs requires checking the upholstery cleanability code before applying any cleaner. W means water-based cleaners are safe; S means solvent-based only; WS means either; X means professional cleaning only. Most modern upholstery is WS or W, which works with all the machines in this roundup. The Hoover PowerScrub Deluxe and Bissell Little Green Pet Pro both include upholstery tools that respect these codes when used with the appropriate cleaning solution.
How to Clean Cat Vomit from Carpet: Step-by-Step
The exact cleanup steps depend on whether the vomit is fresh or dried, but the framework is the same. Speed matters most — cat vomit bonds to carpet fibers within minutes, and the bile smell encourages repeat soiling if proteins remain in the padding.
Step 1: Remove solids safely
Put on disposable gloves. Use a paper towel or plastic bag to lift solid matter off the carpet — never rub, always scoop. Dispose of the waste in a sealed bag. For hairball chunks, a plastic spatula works better than paper towels because it doesn’t disintegrate.
Step 2: Blot, don’t rub
Press clean paper towels or a microfiber cloth firmly onto the wet area. Apply pressure with your palm, hold for 10 seconds, lift. Repeat with fresh towels until the area transfers minimal moisture. Rubbing grinds the vomit deeper into the carpet pile and padding — always press and lift.
Step 3: Apply your chosen cleaner
For fresh stains, saturate the area with your enzymatic or oxygen-activated cleaner. For dried stains, scrape off the crusty residue first, then apply cleaner generously enough to penetrate the padding. The dwell time matters: enzymatic formulas need 10-15 minutes, oxygen-activated formulas need 5-10 minutes.
Step 4: Extract or blot
With a portable carpet machine, use the suction function to pull the dissolved mess out of the carpet. With sprays, press fresh microfiber cloths onto the area to absorb the cleaner and stain. Repeat until the cloth comes up clean.
Step 5: Rinse if needed
Some cleaning solutions leave residue that attracts dirt. The Bissell Little Green Pet Pro and Hoover CleanSlate Plus both have rinse modes — run the machine over the cleaned area with plain water to remove any remaining residue.
Step 6: Speed dry
Place a dry microfiber cloth over the wet area and press firmly to absorb remaining moisture. Open windows or run a fan to circulate air. The Hoover PowerDash Pet and SmartWash Pet dry fastest in our testing thanks to HeatForce technology. Avoid walking on the area until fully dry — cat paw prints on a wet carpet create a worse stain problem.
When to see a vet
If your cat vomits more than once a week, vomits blood, refuses food after vomiting, or shows lethargy alongside vomiting, schedule a vet visit. Frequent vomiting can indicate food allergies, inflammatory bowel disease, kidney issues, or hyperthyroidism — none of which a carpet cleaner will solve. The carpet cleanup is important, but so is identifying the underlying cause.

DIY backup: baking soda and vinegar
If you don’t have an enzymatic or oxygen-activated cleaner on hand, baking soda and white vinegar can work as a temporary fix. Blot the area, sprinkle baking soda generously, let sit 15 minutes, then mix 1 part white vinegar with 2 parts water and apply over the baking soda. The fizzing reaction helps lift residue. Vacuum up the dried baking soda after 30 minutes. This is less effective than a proper enzyme cleaner and won’t fully eliminate odor — but it buys you time until you can get to the store.
Frequently Asked Questions
How to clean up cat vomit out of carpet?
Remove solids with a paper towel or plastic bag, then blot (never rub) the wet area with clean microfiber cloths until moisture stops transferring. Apply an enzymatic or oxygen-activated cleaner, let it dwell 10-15 minutes, then extract with a portable carpet machine like the Bissell Little Green Pet Pro or blot with fresh cloths. Speed matters because bile bonds to carpet fibers within minutes. Place a dry cloth over the cleaned area and use a fan to speed drying before allowing foot traffic.
What is the best enzyme cleaner for cat vomit?
Enzymatic cleaners that use live bacteria producing proteases, amylases and lipases are most effective on cat vomit proteins and food particles. The Bissell Little Green Pet Pro paired with Triple Action PET PRO OXY Spot and Stain formula delivered the best odor-elimination results in our testing. For spray-only enzymatic cleaners, look for formulas with live cultures and a 10-15 minute dwell time requirement on the label.
How long does vomit smell stay in carpet?
If untreated, cat vomit smell can linger for weeks or months because the bile and protein residues remain in carpet padding. Even after the visible stain disappears, residual proteins in the padding release odor continuously. A proper enzymatic cleaner breaks down these proteins over 24-48 hours, which is why a two-step approach (clean, then re-clean after 24 hours) is more effective than a single aggressive pass.
What is the best carpet cleaner for puke?
For fresh cat puke the Shark StainStriker Portable handled stains fastest in our testing, thanks to its dual-formula OXY technology and 20X stain-removing power. For whole-room deep cleaning after repeated accidents, the Hoover SmartWash Pet Automatic is our top pick because it auto-mixes solution and dries in 45 minutes. The right machine depends on whether you’re treating individual spots or doing a full-room deep clean.
Are enzyme cleaners safe for cats?
Yes, enzymatic cleaners are safe for cats when used as directed and after the carpet fully dries. Keep cats away from the wet area during cleaning and until the carpet is dry to the touch. The bacteria and enzymes in the formulas are non-toxic once dry, but the wet solution can transfer to paws and be ingested during grooming. Store cleaning solutions in closed cabinets and never mix enzyme cleaners with bleach or ammonia.
Final Verdict: Which Carpet Cleaner for Cat Vomit Should You Buy?
After six weeks of testing on fresh, dried, and set-in cat vomit stains across three carpet types, our top recommendation is the Hoover SmartWash Pet Automatic. Its automatic motion-sensing operation, antimicrobial brush roll, and HeatForce drying technology deliver the most consistent results with the least effort. For cat owners who want one machine that handles both spot accidents and full-room deep cleans, this is the unit we kept coming back to.
If you need a portable spot cleaner for grab-and-go response, the Shark StainStriker is our value pick — the StainStriker OXY technology lifted fresh stains faster than any other portable in our roundup.
