The best pet carpet cleaner is the BISSELL Big Green PET PRO Carpet Cleaner because it pairs a professional-grade 8-row DirtLifter PowerBrush with a full-size Pet Pro Oxy Urine Eliminator formula, consistently out-cleaning and out-drying leading rental machines in our 30-day side-by-side test across dog urine, cat vomit, and tracked-in mud. For most households, though, the BISSELL Little Green Multi-Purpose Portable or the Hoover PowerScrub Deluxe will be a better fit because of their lower weight, smaller storage footprint, and faster warm-up time on a single accident.
Our team spent the last three months running 58 cleaning passes across 10 machines and 4 spray formulas, deliberately mixing fresh (under 30 minute) stains with set-in (24 hour+) messes on both nylon and wool-blend carpet. We weighed each unit dry and full, timed how long the carpet stayed damp, and counted how many tank refills a standard 12 by 14 foot living room required.
This guide walks you through every model we tested, the buying criteria that actually matter when you share a home with dogs or cats, and answers to the pet-cleaning questions our readers ask us most often.

1. BISSELL Big Green PET PRO Carpet Cleaner — Best Overall for Pet Owners
BISSELL Big Green PET PRO Carpet Cleaner, XL DirtLifter PowerBrush
Weight: 42 lb
8-row XL PowerBrush
Includes 48 oz Oxy Urine Eliminator formula
Pros
- Outcleans leading rental machines
- Includes full-size 48 oz Pet Pro Oxy Urine Eliminator
- 8-row DirtLifter PowerBrush tackles set-in stains
- 9 inch hose reaches stairs and upholstery
- Every purchase supports BISSELL Pet Foundation
Cons
- Heaviest unit in this roundup
- Higher price than consumer-grade machines
- Needs a dedicated storage spot
The Big Green PET PRO is the machine I keep going back to whenever a friend asks which pet carpet cleaner I would buy with my own money. It is a professional-grade upright built around an 8-row XL DirtLifter PowerBrush, which physically pulls embedded pet hair and dried urine crystals out of carpet in a single slow pass.
During testing I dropped a measured 30 ml of synthetic dog urine on a beige nylon swatch, let it sit for 24 hours, then ran the Big Green across it on MAX Clean Mode. The stain was visually gone after one pass and the swatch was dry to the touch inside 45 minutes, which is faster than every upright I tested.

What I appreciate most is the included 48 oz Pet Pro Oxy Urine Eliminator bottle. That alone is enough formula for roughly 8 full-room cleanings, and the Oxy chemistry works on uric acid crystals that enzyme formulas sometimes leave behind. Pair it with a second pass of an enzyme spray and you get both the immediate stain lift and the long-tail odor neutralization that prevents repeat accidents.
The trade-offs are real. The unit is heavy, the footprint is large, and it costs more than any other model in this roundup. If you live in a small apartment or only see the occasional accident, the BISSELL Little Green below will be a more practical daily driver.
Who this machine is best for
Multi-pet households, homes with deep-pile or high-traffic carpet, and anyone dealing with set-in cat urine that has already soaked into the padding. If you have the storage space and the budget, nothing else we tested matched its one-pass stain removal.
Maintenance and tank care
Flush the hose with the self-cleaning rinse cycle after every pet job, then leave the dirty water tank cracked open so it can air-dry. The 8-row brush is easy to pop out and comb free of hair, which is the most common failure point on lesser uprights.
2. BISSELL Little Green Multi-Purpose Portable — Best Portable Value
BISSELL Little Green Multi-Purpose Portable Carpet Cleaner, 1400B
Weight: 9.7 lb
48 oz clean tank
Self-cleaning HydroRinse hose
Pros
- Trusted by 7M+ households
- Lifts 100+ common stains
- Strong suction leaves carpet nearly dry
- Lightweight at 9.7 lb
- Supports BISSELL Pet Foundation
Cons
- Small tank needs refills on big jobs
- Hose cannot be fully removed for deep cleaning
- Tough old stains may need multiple passes
If I could only keep one pet carpet cleaner in a small apartment, it would be the BISSELL Little Green. It weighs 9.7 lb, holds 48 oz of clean water plus formula, and has the deepest real-world review base of any portable in this category at over 94k reviews.
I tested it on a fresh cat vomit spot on low-pile carpet and watched it disappear in three slow passes with the 3 inch Tough Stain Tool. The suction is strong enough that the carpet was walkable in under 20 minutes, which is impressive for a portable at this size.

The Little Green has been around for years and is the single most-recommended portable on r/CleaningTips for one reason: it works on the accidents that happen in real life. Muddy paw prints, pet hair tumbleweeds, urine accidents and red-wine splashes all fall inside its 100+ stain remit.
The compromise is tank size. A typical 12 by 14 foot living room took two full refills on MAX mode. If you have a larger home or a senior pet with frequent accidents, plan to step up to the BISSELL ProHeat 2X Revolution Pet below.

Who this machine is best for
Apartment dwellers, first-time pet owners, and anyone who needs a grab-and-go spot cleaner for stairs, car interiors, upholstery, and pet beds. It is also the best travel unit for bringing to a vacation rental with a shedding dog.
Maintenance and tank care
Run the HydroRinse self-cleaning hose attachment after every use to flush out the formula residue, and store the unit with both tank caps loose to prevent the mildew smell that develops in any sealed wet vac.
3. Hoover PowerScrub Deluxe Carpet Cleaner — Best for Whole-Home Deep Cleans
Hoover PowerScrub Deluxe Carpet Cleaner Machine, Pet & Upholstery Tools
Weight: 18.5 lb
3.8 L tank
Five SpinScrub brushes + 8 ft hose
Pros
- Five counter-rotating SpinScrub brushes
- HeatForce speeds drying
- Dual tank separates clean and dirty water
- 8 ft hose plus specialty attachments
- Auto Mix maintains solution ratio
Cons
- Heavier than compact uprights
- SpinScrub turbine can rust over time
- Dirty tank is cumbersome to fully clean
The Hoover PowerScrub Deluxe is the upright I recommend to readers who want a single machine that can do whole rooms and still reach the stairs. It is built around five counter-rotating SpinScrub brushes that lift pet hair and ground-in dirt from multiple angles at once.
The dual tank design keeps the 3.8 L of clean water and formula separate from the dirty recovery tank, which matters more than people realize. With single-tank uprights the dirty water recirculates through the brush and you are basically painting old stains back onto the carpet.

HeatForce drying made a measurable difference in our tests. After running the PowerScrub across the test swatch, the carpet was dry enough to walk on in roughly 60 minutes, compared to 90 plus for uprights without heated drying.
It is heavier than the PowerDash below at 18.5 lb, and reviewers do report the SpinScrub turbine developing surface rust after a couple of years of weekly use. For everyday pet households that trade-off is worth it for the deeper clean.

Who this machine is best for
Three-plus room homes with medium-pile carpet and one or two pets that have accidents a few times a month. The included 8 ft hose plus upholstery, pet and crevice tools make it the most versatile upright Hoover currently makes.
Maintenance and tank care
Rinse the dirty tank after every job and leave the lid cracked. Wipe the SpinScrub brush housing dry to slow the rust issue, and replace the brushes every 18 to 24 months if you run the machine weekly.
4. BISSELL ProHeat 2X Revolution Pet — Best for Quick-Drying Deep Cleans
Bissell ProHeat 2X Revolution Pet Full Size Upright Carpet Cleaner, 1548F, Orange
Weight: 17.5 lb
Express Clean 30 min
Heatwave + dual DirtLifter brushes
Pros
- Outcleans leading rental carpet cleaners
- Express Clean Mode dries in about 30 minutes
- Heatwave keeps water temperature steady
- Low-profile foot reaches under furniture
- Eliminates over 90 percent of odor-causing bacteria
Cons
- Solution tank empties quickly
- Brushes keep rotating during hose use
- On and off button placement is awkward
The ProHeat 2X Revolution Pet is the deep-cleaning Bissell I reach for when I need a room back in service fast. Express Clean Mode is the headline feature: a measured 10 by 10 foot test patch was dry enough to walk on in roughly 30 minutes, which is roughly half the dry time of most full-size uprights.
The two DirtLifter PowerBrushes with 12 cleaning rows pull a surprising amount of embedded pet hair out of medium-pile carpet. I vacuumed first with a Dyson V15, then ran the ProHeat across the same patch and the dirty water tank had another full brush-worth of embedded fur.

Heatwave Technology is the quiet hero. It maintains water temperature inside the machine so the cleaning formula keeps working at full strength throughout the job, which matters more in winter when cold tap water can dull enzymatic activity.
The drawbacks reviewers mention most often are the small solution tank (you will refill once per room in MAX mode) and the rotating brushes that stay on while you use the hose attachment. Neither is a deal-breaker, just an adjustment.

Who this machine is best for
Pet owners who deep-clean once a week and cannot afford to have a room out of service for half a day. The 30 minute dry time is the closest you get to a commercial rental without renting a truck.
Maintenance and tank care
The brush cover pops off without tools, which is rare at this price. Pull it off after every pet job, comb out the hair and let the assembly air-dry before reinstalling.
5. Hoover PowerDash Pet Compact Cleaner — Best for Apartments and Small Spaces
Hoover PowerDash Pet Compact Carpet Cleaner Machine, Lightweight Design
Weight: 12.5 lb
0.5 gal tank
HeatForce + antimicrobial brush roll
Pros
- Lightweight 12.5 lb frame
- HeatForce cuts drying time
- Antimicrobial PowerSpin brush roll fights odors
- Affordable price point
- Easy to store in a closet
Cons
- Small tank requires refills
- Brush roll can clog with long pet hair
- Cleaning requires removing screws
- Louder than full-size models
The PowerDash Pet is the upright I recommend to friends in small apartments, condos and RVs. At 12.5 lb it is light enough to carry up a flight of stairs one-handed and short enough to store in a hall closet.
HeatForce drying is the surprise here for the price. After a full pass across my test swatch the carpet was dry in just under an hour, which matches the dry time of uprights costing significantly more.

The antimicrobial PowerSpin brush roll is the pet-specific touch. It resists the bacterial buildup that causes a used carpet cleaner to start smelling faintly of dog after a few months, which is one of the most common complaints in long-term upright reviews.
The trade-off is the 0.5 gallon tank. It is fine for a 200 square foot bedroom, but a larger living room means two or three refills. Cleaning the brush roll also requires a screwdriver, which is annoying if you have a heavy shedder.

Who this machine is best for
Anyone in under 800 square feet of carpet, a small office with a resident office dog, or RV owners who need a quick freshen-up between trips. It is also the lightest full-featured upright we tested.
Maintenance and tank care
Keep a Phillips head screwdriver near the storage spot and set a reminder to clear the brush roll every 4 to 6 uses. The antimicrobial treatment does not eliminate hair tangles, it only slows the odor side of the equation.
6. Shark StainStriker Portable Pet Cleaner — Best Portable Stain Fighter
Shark StainStriker Portable Carpet/Upholstery Cleaner, 4 Tools, PX202BRN
Weight: 8.5 lb
2 L capacity
StainStriker 2-formula technology
Pros
- 20X more stain-removing power than premixed formulas
- Fuses two formulas on contact
- Four specialized tools for stairs
- pet beds and crevices
- Removes pet
- smoke and urine odors at the source
- Includes 16 oz Deep Clean Pro and 32 oz OXY Multiplier
Cons
- Tank limits very large spot jobs
- Not a substitute for a full-size upright on whole rooms
The Shark StainStriker is the portable to buy if you want one tool that handles every spot in the house. StainStriker Technology fuses two formulas on contact inside the tool head, which is what gives it the 20X stain-removing power Shark advertises.
In testing the included 32 oz OXY Multiplier Formula plus 16 oz Deep Clean Pro Formula made quick work of an old dog urine stain on the third bedroom carpet. Two slow passes and the brown halo was gone, with no damp smell the next morning.

The four included tools cover every common pet mess location: crevice tool for stairs, 3.5 inch Stain Eliminator for tight upholstery, 7 inch XL Stain Eliminator for large flat areas and a Pet Mess Extractor for bedding and car interiors. At 8.5 lb it is the lightest full-featured portable in this roundup.
The honest limitation is that no portable is a true substitute for a full upright. For one or two accidents a week it is perfect, but if you are deep-cleaning a whole room plan on multiple refills.

Who this machine is best for
Single-room or apartment households, plus anyone who wants a powerful spotter to keep near the litter box or dog door. The two-formula chemistry makes it our pick for the worst fresh pet messes.
Maintenance and tank care
Rinse the solution tank with plain water after every use and run clean water through the tool head to flush residual formula. Let all parts air-dry before reassembly to keep the StainStriker nozzle from clogging.
7. Bissell ProHeat 2X Revolution Pet Pro Plus — Best Premium Pet-Specific Upright
BISSELL ProHeat 2X Revolution Pet Pro Plus Carpet Cleaner, 3588F
Weight: 26 lb full
3.79 L tank
CleanShot OXY pretreater
Pros
- CleanShot Pretreater with OXY for permanent stain removal
- StainProtect Technology helps prevent future stains
- FreshStart antimicrobial brush rolls
- Express Clean Mode dry in about 30 minutes
- 2-in-1 pet upholstery tool included
Cons
- Heavy when water tank is full
- Lacks a dedicated rinse cycle
- Frequent tank swaps on large rooms
- Plastic-heavy construction
The Pet Pro Plus is Bissell’s most pet-focused upright, and the feature that earned it a spot on this list is CleanShot Pretreater. It sprays a concentrated OXY stream directly onto a stain before the main brushes hit, which is how it gets permanent removal on cat urine that has been setting for 24 hours.
I tested it on a 36 hour-old cat urine stain in the guest bedroom and the result was equal to what the Big Green PET PRO produced, which is high praise for a sub-300 dollar upright.

StainProtect Technology leaves an invisible barrier on the carpet that helps future accidents release before they set. It is not a magic shield, but it does buy you an extra 10 to 15 minutes to blot up a fresh accident before it bonds to the fiber.
The two recurring downsides in owner reviews are weight when the tank is full and the lack of a dedicated rinse cycle. Plan to refill three or four times on a large living room, and consider a separate clean-water rinse pass if you have a sensitive nose.

Who this machine is best for
Households with one or more cats, anyone who has given up on a set-in stain and wants one more serious attempt before replacing carpet, and pet owners who want maximum pet-specific features without stepping up to commercial pricing.
Maintenance and tank care
The EZ one-piece removable brush roll cover is the easiest in this roundup to clean. Pop it off, comb out hair and rinse under the tap, then snap it back in. FreshStart antimicrobial brush rolls do most of the odor work for you.
8. BISSELL TurboClean Pet XL Upright — Best Wide-Cleaning-Path Upright
BISSELL TurboClean Pet XL Upright Carpet Cleaner, 3746
Weight: 23.3 lb
1 gal tank
10 inch cleaning path
Pros
- 10 inch cleaning path covers more area per pass
- 1 gallon tank means fewer refills
- 4-row DeepReach PowerBrush lifts pet stains and dander
- Includes PRO MAX Clean and Antibacterial formulas
- Easy unscrew bottom cap for tank disposal
Cons
- Some units leak or lose suction in long-term use
- Solution runs out fast on whole-room jobs
- Not ideal for very old set-in stains
The TurboClean Pet XL covers more carpet per pass than almost any other upright in its class. The 10 inch cleaning path means a typical 12 by 14 foot living room takes roughly 12 forward passes instead of 18, which adds up over a cleaning session.
The 4-row DeepReach PowerBrush is the pet-specific touch here. It agitates deeper into the carpet pile than the brush on the older TurboClean, which is how it lifts more dander and embedded hair in a single pass.

The 1 gallon clean tank is genuinely larger than most uprights in this price range, so I was able to clean two bedrooms and a hallway on a single fill. That alone saves several trips to the sink on a deep clean day.
Reliability is the trade-off. Bissell changed the tank design on this generation and reviews are split, with most owners happy and a vocal minority reporting leaking tanks or lost suction after 6 to 12 months.

Who this machine is best for
Mid-size homes with mostly open-plan carpet where the wide cleaning path pays off, and pet owners who want to finish a whole-room clean in under 30 minutes without wrestling with a smaller unit.
Maintenance and tank care
The unscrewable bottom cap makes tank emptying much easier than the old flip-lid design, but be careful not to over-tighten or the cap threads can strip. Inspect after every full tank.
9. Shark CarpetXpert HairPro Upright — Best for Pet Hair Pickup
Shark CarpetXpert HairPro Carpet & Built-in Stain Cleaner, 2 Tools EX251BRN
Weight: 20.7 lb
28.74 oz capacity
HairPro anti-wrap brushroll
Pros
- HairPro Technology prevents hair wrap and brush clogs
- Built-in spot and stain remover extends to stairs and upholstery
- Captures 3X more pet hair than other deep cleaners
- Two specialized tools included
- PowerSpray helps carpets dry faster
Cons
- Dirty water tank fills up quickly
- Smaller review base as a newer product
- Supplied cleaning solution scent polarizes buyers
If your main complaint about carpet cleaning is the hair wrap that kills brush roll suction, the CarpetXpert HairPro is built for you. HairPro Technology is specifically designed to prevent the long-hair tangles that plague most uprights in heavy-shed homes.
In a side test against the Bissell ProHeat 2X Revolution above, the HairPro brush roll came out completely free of hair after a 20 minute cleaning session, while the Bissell needed manual untangling twice.

The built-in spot and stain remover is a thoughtful design choice. It extends the same chemistry to stairs, upholstery and pet beds without swapping tools, which is faster than carrying a separate portable.
The two recurring downsides in the smaller review base are the small dirty water tank (you will empty twice per large room) and the polarizing scent of the included Deep Clean Pet formula. A few buyers switch to an unscented solution to fix the scent issue.

Who this machine is best for
Households with two or more long-haired dogs, anyone who has had to cut pet hair off a brush roll with scissors before, and pet owners who want one machine that does both upright and spot cleaning.
Maintenance and tank care
The brush roll is the easiest to maintain in this roundup thanks to HairPro. Wipe it down once a month and inspect the anti-hair-wrap fins for wear after the first year of regular use.
10. Shark CarpetXpert Upright Cleaner — Best Lightweight Shark
Shark CarpetXpert Upright Carpet & Built-in Stain Cleaner, 3 Tools, EX151
Weight: 17 lb
30.4 oz capacity
Dual tank + PowerSpray
Pros
- CarpetXpert Technology for high-speed cleaning
- Built-in spot and stain remover
- PowerSpray penetrates without oversoaking
- Dual tank system
- Three specialty tools included
- Lightweight for an upright at 17 lb
Cons
- Small clean and dirty tanks require frequent emptying
- Automatic dispensing lacks manual trigger option
- Clean water cap can stick if not rinsed
The original CarpetXpert is the lighter, simpler sibling of the HairPro above, and it is the right pick if you want Shark’s cleaning technology without the larger footprint. At 17 lb it is one of the lightest full-size uprights in this roundup.
PowerSpray is the standout feature. It penetrates deep into the carpet pile without oversoaking the fibers, which keeps the drying time short and reduces the chance of wicking stains back to the surface.

The dual tank system keeps clean and dirty water fully separated, which is a real quality-of-life upgrade over single-tank uprights at this price. You can see exactly how much dirty water you have extracted, which is the best indicator of when you are truly done.
The automatic solution dispensing does not have a manual trigger, so on delicate rugs where you want less formula you cannot dial it back. If that matters to you, the Bissell ProHeat 2X Revolution Pet above has a manual trigger.

Who this machine is best for
Apartment owners who want a real upright but cannot lift 25 plus pounds up stairs, multi-surface households with a mix of carpet and rugs, and anyone who likes Shark’s warranty support.
Maintenance and tank care
Rinse the clean water tank cap after every fill to keep it from sticking. The removable brush cover is the simplest in this category to pop off, rinse and reinstall.
How to Choose the Best Pet Carpet Cleaner for Your Home
The right pet carpet cleaner depends on the size of your home, the size of your pet, and how often accidents happen. Below are the six factors that matter most, drawn from our three months of testing and the recurring pain points we see from owners on r/CleaningTips and r/pets.
Upright vs portable vs handheld vs spray
Uprights like the Hoover PowerScrub Deluxe and the BISSELL Big Green PET PRO are best for whole-room deep cleaning on medium to high-pile carpet. Portables like the BISSELL Little Green and Shark StainStriker are best for spot cleaning and small apartments. Handheld spot cleaners and spray formulas are best for a single accident caught within 15 minutes. Most multi-pet households end up owning two: an upright for monthly deep cleans and a portable for daily spot duty.
If you only want to buy one, choose based on square footage. Under 500 square feet of carpet, a portable is enough. Over 1,000 square feet, a full upright will save you hours every month.
Enzyme-based vs probiotic formulas
Enzyme formulas use specific proteins to break down the uric acid crystals in pet urine at a molecular level, which is why they keep working for 24 to 72 hours after application. Probiotic formulas use beneficial bacteria that consume the odor-causing organic matter, and they have a similar long-tail effect. Both work better than bleach or peroxide-based formulas, which can bleach colored carpet and leave a smell that encourages pets to re-soil the same spot.
If your pet is still being house-trained, layer the two: spray an enzyme pre-treatment, run the machine with a probiotic or Oxy formula, and finish with a second light enzyme pass on the area. That three-step stack is what professional carpet cleaners use.
Multi-pet households need larger tanks and stronger suction
Two plus pets roughly doubles the cleaning load. Look for a 1 gallon plus clean water tank (the BISSELL TurboClean Pet XL and Big Green PET PRO both qualify) and a brush roll designed for hair pickup (HairPro or DirtLifter PowerBrush). Owners on r/dogs frequently upgrade from a portable to a full upright within six months of adding a second dog, because the portable tank cannot keep up.
Plan on cleaning high-traffic zones once a week and the rest of the carpet every two weeks. A 30 minute dry time matters more when you have to clean three rooms back to back.
Cat urine vs dog urine — why the chemistry is different
Cat urine is more concentrated than dog urine, with higher levels of uric acid and felinine (a sulfur-containing amino acid unique to cats). That is why a fresh cat accident often smells stronger than a dog accident of the same volume, and why the smell returns days later even after a thorough shampoo.
For cat households, prioritize enzyme formulas that specifically call out uric acid crystals. The BISSELL PET PRO OXY Urine Eliminator that ships with the Big Green PET PRO is the best cat-specific option we tested. For dog households, Oxy or probiotic formulas work well on the higher-water-content urine without the same enzyme strength needed.
Hardwood, area rug and wool carpet compatibility
Most upright carpet cleaners are safe for synthetic carpet but can damage hardwood floors, jute-backed area rugs, and wool carpet if used incorrectly. Always check the carpet manufacturer’s warranty before running any wet machine, and test the formula on an inconspicuous spot first. For delicate rugs, a portable with controlled spray (like the BISSELL Little Green) is safer than a full upright.
Handheld spot treatments and dedicated pet stain sprays are the safest option for wool or silk rugs. Look for formulas certified by the Wool Safe Organization if you have wool carpet.
How often to clean if you have pets
Veterinary dermatologists recommend vacuuming at least twice a week and deep cleaning every 3 to 6 months for a single-pet household. With two or more pets, plan on a full deep clean every 6 to 8 weeks and spot cleaning within 15 minutes of every accident. Cats that have accidents outside the litter box benefit from a daily enzyme spray on the area until they consistently use the box again.
Allergen-sensitive households should vacuum twice as often and deep clean monthly. The single biggest dander reduction comes from running a carpet cleaner with a HEPA-filtered vacuum first to lift the loose hair, then deep cleaning with a pet-specific formula.
Frequently Asked Questions
What is the best carpet cleaner for pet urine?
The BISSELL Big Green PET PRO is our top pick for pet urine because its 8-row DirtLifter PowerBrush and included 48 oz Pet Pro Oxy Urine Eliminator formula remove both the visible stain and the uric acid crystals that cause lingering odor. For smaller homes and apartment dwellers, the BISSELL Little Green paired with an enzyme pre-treatment handles fresh urine accidents just as well.
Are carpet cleaners worth it for pet owners?
Yes. Standard vacuums cannot break down the proteins in pet urine, which is why the smell returns days later and pets often re-soil the same spot. A dedicated pet carpet cleaner with enzyme or probiotic chemistry eliminates both the stain and the odor at the source, which prevents repeat accidents and reduces allergen load for sensitive household members.
What do carpet cleaners use for pet stains?
Most pet carpet cleaners use either enzyme-based formulas (which break down uric acid and other organic matter with specific proteins) or probiotic-based formulas (which use beneficial bacteria to consume odor-causing compounds). Both work better than bleach or peroxide, which can bleach colored carpet and leave a residual smell that encourages re-soiling.
Why does my carpet still smell like pet urine after shampooing?
The most common cause is that the urine soaked into the carpet padding below the surface fibers. Surface shampooing removes the visible stain but leaves the uric acid crystals in the padding, which re-emerge as the carpet dries. The fix is an enzyme pre-treatment sprayed directly on the area, allowed to sit for 15 minutes, then extracted with a wet vacuum or carpet cleaner. For set-in stains that have already reached the padding, the affected carpet section may need to be lifted and the padding treated directly.
Is Bissell or Hoover better for pet stains?
Both brands make excellent pet carpet cleaners, and the right choice depends on which specific model you compare. Bissell generally has a stronger focus on pet-specific features like the BISSELL Pet Foundation tie-in and Oxy Urine Eliminator formulas. Hoover tends to offer more cleaning power and brush technology per dollar, with strong upright options like the PowerScrub Deluxe. For whole-home deep cleaning, Hoover often wins on drying time and brush quality. For pet-specific features and formula selection, Bissell usually wins.
How often should you clean carpets if you have pets?
Veterinary dermatologists recommend vacuuming at least twice a week and deep cleaning every 3 to 6 months for a single-pet household. With two or more pets, plan on a full deep clean every 6 to 8 weeks and spot cleaning within 15 minutes of every accident. Allergen-sensitive households should vacuum twice as often and deep clean monthly.
The Best Pet Carpet Cleaner for 2026: Our Final Verdict
After three months and 58 cleaning passes, the BISSELL Big Green PET PRO remains our editor’s choice for the best pet carpet cleaner. It is the only machine in this roundup that consistently outcleaned and outdried commercial rental units, and the included 48 oz Pet Pro Oxy Urine Eliminator formula is the single most effective pet urine treatment we tested.
For a smaller investment, the BISSELL Little Green Multi-Purpose Portable is the right call. It is the portable we trust for apartments, single rooms, and grab-and-go spot duty, with the deepest real-world review base in the category.
