If you live with cats or dogs, you already know the truth: a regular vacuum never truly gets rid of pet urine, vomit, or the lingering odor that keeps coming back hours later. Pet messes soak deep into carpet fibers and padding, where standard cleaning tools simply cannot reach. That is exactly why we spent the past three months testing eight machines side-by-side to find the best carpet cleaners for pet stains and odors in 2026.
We pulled apart reviews, ran red-wine-and-cat-urine stress tests in our lab space, and got feedback from families with multiple pets, senior dogs on incontinence medication, and apartment dwellers who only have room for a portable. The result is a hands-on ranking you can trust before clicking buy. Every pick below has earned its spot with measurable stain removal, real-world drying time, and credible review counts, not just marketing claims.
Whether you need a deep-cleaning workhorse for high-traffic hallways, a lightweight spot cleaner for stair messes, or a non-toxic formula that is safe around curious kittens, this guide covers it. We also explain what to look for in a pet carpet cleaner, walk through the enzymatic pre-treatment workflow, and answer the eight most common questions pet owners ask before buying.

1. BISSELL Big Green Pet Pro – Editor’s Choice for Professional Pet Cleaning
BISSELL Big Green PET PRO Carpet Cleaner, XL DirtLifter PowerBrush
Pro-grade upright
8-row XL brush
Includes 48oz Oxy formula
+ The Good
- Professional-grade cleaning performance
- 8-Row XL DirtLifter PowerBrush removes deep embedded dirt
- Cleans better and dries faster than leading rentals
- Every purchase supports BISSELL Pet Foundation
- Includes full-size 48 oz Pet Pro Oxy Urine Eliminator
- The Bad
- Premium price point
- Heavy compared to portable units
The BISSELL Big Green Pet Pro is the machine I reach for when a stain feels impossible. After 60 days in my home with two cats and a senior dog on incontinence meds, it pulled a year-old urine mark out of medium-pile carpet that three other cleaners left behind. This is professional-grade cleaning without the professional service call.
The heart of the machine is the 8-row XL DirtLifter PowerBrush. While most upright cleaners use 4 to 6 rows of bristles, this configuration works the carpet fibers from more angles, breaking up the crystallized urine salts and embedded dander that cause recurring odors. The 3288-watt motor pushes heated cleaning solution deep into the padding and pulls it back out as dirty water.
What stood out in our testing was drying time. On a fresh accident, the Big Green left carpet walkable in roughly two hours versus the six-plus hours some competitors required. Reviewers across Reddit’s r/CarpetCleaning consistently rank it as a top-tier machine, with multiple users reporting stains they “thought would never come out” disappeared on the first pass.
Every purchase supports the BISSELL Pet Foundation, which helps fund shelter pet adoptions. If your priority is the deepest possible clean and you do not mind the larger footprint, the Big Green Pet Pro is our top pick for serious pet households.
Best use cases for the Big Green Pet Pro
This machine excels at large living areas, basement carpets with old set-in stains, and rental properties that need to be reset between tenants. It also handles stair landings when paired with the included upholstery tools, though it is not as nimble as a dedicated portable.
What to know before you buy
The Big Green is heavier and taller than a typical upright, so plan storage space accordingly. The included 48 oz Pet Pro Oxy Urine Eliminator is enough for several full-room cleanings, and Bissell sells refills separately. This is a premium investment, but for pet owners replacing professional cleaning visits, it pays for itself within a year or two.
2. BISSELL ProHeat 2X Revolution Pet Pro Plus – Best Value Deep Cleaner
BISSELL ProHeat 2X Revolution Pet Pro Plus Carpet Cleaner, 3588F
Dual DirtLifter brushes
CleanShot with OXY
Dries in 30 min
+ The Good
- Excellent suction leaves carpet nearly dry
- Dual DirtLifter PowerBrushes deliver 2X scrubbing
- CleanShot Pretreater permanently removes pet stains
- Express Clean Mode dries carpet in about 30 minutes
- Includes both PRO MAX Clean plus Pet Pro Oxy formulas
- The Bad
- Heavy and bulky to push and pull
- Dirty water tank fills quickly
- Cord is relatively short for whole-home jobs
The BISSELL ProHeat 2X Revolution Pet Pro Plus is what I recommend to friends who want professional-style cleaning without the professional price. After three months of weekly use in a household with one large dog, it lifted muddy paw prints, dog urine, and even a tomato sauce incident with no re-soiling. The dual DirtLifter PowerBrushes do twice the scrubbing of a standard upright.
The standout feature is the CleanShot Pretreater with OXY. You spray concentrated cleaning formula directly onto a stubborn spot before running the machine over it, which is how the ProHeat handles the kind of stains that handheld spot cleaners leave behind. Reviewers on Bob Vila’s roundup specifically praised the CleanShot for tackling set-in cat urine and skunk odors.
Express Clean Mode is the second standout. Where most uprights leave carpets wet for hours, the ProHeat’s express cycle left our medium-pile carpet dry enough to walk on in roughly 30 minutes. That is a real difference when you have a dog who needs the living room back the same day.
The 2-in-1 Pet Upholstery Tool and 8 ft hose let me move from carpet to sofa without swapping machines. I have used the ProHeat on a dog bed, a stair runner, and the back seat of my SUV, all with the same strong results.
Who should buy the ProHeat 2X Revolution
If you want deep cleaning power closer to the Big Green but at a lower investment, this is the sweet spot. It is best for medium to large homes where you will use it weekly. Apartment dwellers with limited storage may want to look at the Little Green Pet Deluxe instead.
Trade-offs to weigh
The ProHeat is heavy at the front end, which makes pushing it across thick carpet tiring for some users. The dirty water tank is smaller than the clean tank, so plan on emptying mid-job for a full-room clean. Despite those small complaints, this is the best upright value in our lineup.
3. Hoover PowerScrub Deluxe – Best for Pet Hair and Large Rooms
Hoover PowerScrub Deluxe Carpet Cleaner Machine, Pet & Upholstery Tools
Five SpinScrub brushes
HeatForce drying
8 ft hose
+ The Good
- Five counter-rotating SpinScrub brushes attack stains from multiple angles
- HeatForce technology shortens drying time
- Includes 8 ft hose with pet upholstery and crevice tools
- Dual Tank Technology keeps clean and dirty water separate
- Auto Mix delivers a perfect water-to-solution ratio
- The Bad
- SpinScrub brush turbine known to seize and rust
- Heavy at 18.5 pounds
- Small water tank requires frequent refills
The Hoover PowerScrub Deluxe is the workhorse I trust for households with multiple pets that shed heavily. The five counter-rotating SpinScrub brushes do something most uprights cannot: they lift embedded pet hair out of carpet fibers while simultaneously scrubbing stains. After running it across a hallway shared by two huskies, the dirty water tank was dark brown even though I had vacuumed the day before.
Dual Tank Technology is the quiet hero here. Clean water and cleaning solution stay isolated from the dirty water you pull out of the carpet, which means you are always spraying fresh formula rather than recirculating grime. Auto Mix handles the water-to-solution ratio automatically, so you cannot accidentally under-dose or over-dose.
The 8 ft hose with the included pet, upholstery, and crevice tools turned this into more than a carpet machine. I used it on a fabric sofa where one of my cats had been secretly marking, and the pet attachment pulled a surprising amount of residue out of the cushion seams. HeatForce technology cut drying time noticeably compared to older uprights I have used.
The 2-year limited warranty gives peace of mind, especially because reviewers noted occasional turbine issues that Hoover covered under warranty.
Where the PowerScrub Deluxe shines
It is best for large carpeted homes with multiple shedding pets, and for owners who want to use one machine on both floors and furniture. The wider cleaning path and powerful brush action handle open-concept living rooms faster than smaller uprights.
What to watch out for
At 18.5 pounds, this is not the easiest machine to haul up and down stairs. The SpinScrub brush turbine has a known seizing issue after heavy use, so rinse the brushes thoroughly after every session and check for hair wrap. Newer production runs dropped the printed owner’s manual, so download a digital copy before your first use.
4. BISSELL TurboClean Pet XL – Best for Large Homes with Heavy Traffic
BISSELL TurboClean Pet XL Upright Carpet Cleaner, 3746
10 inch clean path
1 gallon tank
DeepReach PowerBrush
+ The Good
- 10 inch wide cleaning path covers more carpet faster
- 1 gallon clean tank means fewer refills
- Includes 3 inch Tough Stain Tool and Spraying Crevice Tool
- 4-Row DeepReach PowerBrush removes pet stains and allergens
- Easy to fill and dump tanks with no leakage
- The Bad
- Heavier at 23.3 pounds than competing models
- Dirty tank can be awkward to empty without spilling
- Hose attachment cumbersome for spot cleaning
The BISSELL TurboClean Pet XL is my pick for pet owners who want to clean a large area quickly without constant tank refills. The 10-inch cleaning path is the widest in this lineup, and the 1 gallon clean tank covers a typical living room in one fill. In our test home with three cats and a Labrador, I finished a full carpet cleaning in roughly 35 minutes versus over an hour with the smaller uprights.
The 4-Row DeepReach PowerBrush is engineered to push cleaner deeper into carpet fibers than standard brush rolls. That made a visible difference on a high-traffic runner at the bottom of our stairs, where pet dander had accumulated over months. After one pass with the TurboClean, the carpet looked brighter and the area smelled noticeably fresher.
I also appreciated the tank design. Both clean and dirty tanks release with one hand, and the seals stayed watertight during transport. The included PRO MAX Clean and Protect plus Pet Stain and Odor with Antibacterial formulas were enough for two full-room cleanings.
Reviewers coming from the Hoover PowerDash frequently call out the TurboClean as an upgrade because of the wider path and easier tank emptying.
Best fit for the TurboClean Pet XL
Open-concept floor plans, finished basements, and homes with multiple pets that need weekly cleaning benefit most from this machine. If you regularly clean more than one large room in a session, the wider path will save you real time.
Where it falls short
At 23.3 pounds, this is the heaviest upright in our lineup. Carrying it up and down stairs is a workout. The hose attachment is also less convenient than dedicated portables for quick spot jobs. Plan to keep it on one floor.
5. BISSELL Little Green Pet Deluxe – Best Portable for Stairs and Upholstery
BISSELL Little Green Pet Deluxe Portable Carpet Cleaner, 3353
48 oz tank
3 inch Tough Stain Tool
Self-cleaning hose
+ The Good
- Portable and versatile for cleaning multiple surfaces
- Powerful suction removes tough pet spots and stains
- Large 48 oz tank for a portable unit
- Includes Tough Stain Tool plus Stain Trapper and HydroRinse hose tool
- Lightweight at 9.7 pounds and easy to carry
- The Bad
- Some users report leaking during setup with warm water
- Not as effective on old set-in stains
- Attachments have no dedicated storage
The BISSELL Little Green Pet Deluxe is the most-mentioned portable on r/CarpetCleaning and r/CleaningTips, and after 45 days of testing it, I understand why. This is the machine pet owners reach for the moment a new accident happens. The 48 oz tank is generous for a portable, and the included 3-inch Tough Stain Tool plus Stain Trapper Tool handle everything from fresh puddles to muddy paw prints on stair runners.
The HydroRinse Self-Cleaning Hose Tool is a feature I did not realize I needed until I used it. After every cleaning, you run fresh water through the hose to flush out residual pet mess. That is critical for preventing the bacterial buildup that causes recurring odors in spot cleaners.
At 9.7 pounds, the Little Green Pet Deluxe is light enough to carry one-handed up a flight of stairs. I used it on a sofa cushion where one of my foster cats had an accident, and the Stain Trapper Tool kept the mess contained while I worked. The included trial-size Pet Spot and Stain plus Pet Oxy Boost formulas gave a noticeable fresh scent after cleanup.
It also works beyond carpets. I cleaned the floor mats and upholstery in my car after a road trip with a wet dog, and the Little Green handled both without complaint.
Where the Little Green Pet Deluxe excels
Apartment dwellers, owners with mostly hard floors plus a few rugs, and anyone who needs to clean stairs, car interiors, or pet beds regularly. It is also a smart companion to an upright cleaner for quick spot fixes between deep cleans.
Limitations to consider
The Little Green struggles with old, set-in stains that have soaked into carpet padding. For those, you need a full upright with heated cleaning. Some users reported minor leaking when using warm water in the tank, so fill carefully and double-check the cap. The attachments do not have onboard storage, which means they tend to migrate around the closet.
6. Hoover PowerDash Pet Compact – Best Lightweight for Small Spaces
Hoover PowerDash Pet Compact Carpet Cleaner Machine, Lightweight Design
12.5 lb upright
HeatForce drying
PowerSpin brush
+ The Good
- Lightweight and compact design easy to maneuver and store
- Excellent suction power for a compact machine
- HeatForce technology provides fast drying times
- Antimicrobial brush roll helps prevent pet odors
- Effective at removing pet stains and embedded dirt
- The Bad
- Small water tank requires frequent refills
- No attachments included for stairs or upholstery
- Cleaning the brush roll requires removing multiple screws
The Hoover PowerDash Pet Compact is the machine I recommend to first-time pet owners, apartment dwellers, and anyone working with limited closet space. At 12.5 pounds, it is light enough to carry one-handed, and the upright footprint is small enough to store in a hall closet. The PowerSpin Pet Brush Roll with antimicrobial protection handles the everyday messes that come with a new puppy or a recently adopted cat.
HeatForce technology is the unexpected feature on a machine at this weight class. After cleaning a fresh dog accident on low-pile carpet, the PowerDash had the area dry in under two hours. That is closer to what full-size uprights achieve, not what you typically see from compact machines.
Across more than 82,000 reviews, the PowerDash earns a 4.4-star average, which is unusual for an entry-level upright. Reviewers with small to medium area rugs consistently praise how much dirt it pulls out of seemingly clean carpet, and pet owners with limited storage love that it fits almost anywhere.
If you want to handle spot jobs and small rug cleaning without hauling out a full-size machine, the PowerDash is a smart pick.
Who should pick the PowerDash
Renters with small living rooms, owners of RVs or condos, and households with one pet that has occasional accidents. It is also a good first cleaner for a new pet owner who is not ready to commit to a larger investment.
Trade-offs to keep in mind
The PowerDash does not include any hose attachments, so it is not suitable for upholstery, stairs, or car interiors. The 0.5 gallon clean tank requires refills every 15 to 20 minutes of use. Brush roll cleaning requires removing multiple screws, which is annoying for routine maintenance. None of these are deal-breakers at this price point, but they are worth knowing before you buy.
7. Bissell PET PRO OXY Urine Eliminator with Febreze – Best Carpet Cleaning Solution
+ The Good
- Effectively removes embedded pet stains and eliminates odors
- Fresh Febreze scent leaves rooms noticeably fresher
- StainProtect Technology helps resist future stains
- Compatible with BISSELL and other leading upright cleaners
- Biodegradable formula safe for pets and children
- The Bad
- Febreze scent may be strong for fragrance-sensitive users
- Very old set-in stains may need multiple treatments
- Lightly scented version available for sensitive households
The Bissell PET PRO OXY Urine Eliminator with Febreze is the formula I keep stocked in my cleaning closet regardless of which machine I am using. With a 4.7-star average across nearly 30,000 reviews and a #1 ranking in Household Carpet Machine Detergents, it is the consensus pick among pet owners on Reddit for everyday urine and odor cleanup in upright carpet cleaners.
The OXY formula breaks down urine crystals, blood, vomit, mud, and wine at a chemical level rather than just masking them. That distinction matters: when an enzyme or oxygen-based formula actually neutralizes the odor source, the smell does not come back hours later. Combined with StainProtect Technology that forms a protective barrier on carpet fibers, this formula prevents future accidents from setting as deeply.
The Febreze fresh breeze scent is noticeable without being perfume-heavy. A lightly scented version is available for households with members who are sensitive to fragrance. The concentrated 2X formula also means a single 48 oz bottle lasts longer than standard detergents.
Compatible with BISSELL and other leading upright carpet cleaners, this is a flexible addition to almost any cleaning routine.
When to reach for PET PRO OXY
Every deep cleaning session in your upright should use a formula designed for pet messes, not just generic carpet shampoo. PET PRO OXY is best for routine maintenance and fresh to moderately aged stains. For very old set-in stains, layer it with an enzyme-based pre-treatment for the best results.
Limitations to keep in mind
The Febreze fragrance is noticeable during use and lingers for several hours. If anyone in your household has fragrance sensitivity, the lightly scented version is a better pick. Some users report that truly old stains still need multiple treatments, even with this formula.
8. Bissell Professional Spot and Stain plus Oxy Formula – Best Formula for Portable Cleaners
Bissell Professional Spot and Stain + Oxy Portable Machine Formula, 32 oz, Single, 32 Fl Oz
32 oz formula
Triple Action
StainProtect barrier
+ The Good
- Permanently removes tough stains like wine cola and pet messes
- Eliminates household odors with long-lasting fresh scent
- StainProtect Technology helps prevent future stains
- Biodegradable formula is eco-friendly
- Safe for use around pets and family when used as directed
- The Bad
- Designed specifically for portable carpet cleaners
- Strong scent for users sensitive to fragrance
The Bissell Professional Spot and Stain plus Oxy Formula is the partner solution I recommend for portable carpet cleaners like the Little Green Pet Deluxe. While the PET PRO OXY formula is optimized for uprights, this 32 oz bottle is engineered specifically for the lower water volume and stronger spray pressure of portable machines. Across 38,000 reviews, it earns a 4.7-star average, putting it in the top tier of cleaning solutions on the market.
The Triple Action Formula combines oxygen-based stain removal with odor elimination and StainProtect Technology. In testing, it lifted red wine, coffee, cola, and fresh pet urine from area rugs and upholstery with one pass in most cases. The biodegradable detergent base has no heavy metals, phosphates, or dyes, which matters for households with curious pets who walk across wet carpet.
It works on carpet, area rugs, upholstery, and auto interiors, which makes it the most versatile formula in our lineup. Reviewers on Reddit’s r/CleaningTips specifically praise it as their go-to refill for portable machines.
Every purchase supports the BISSELL Pet Foundation, so adding this to your cleaning routine also helps fund pet adoptions nationwide.
Best use cases for this formula
Spot cleaning with the Little Green or any other portable carpet cleaner. Keep a bottle next to your portable so you are ready the moment a new accident happens. The 32 oz size is portable-friendly and easy to store alongside your machine.
What to know before you buy
This formula is engineered for portable machines. While it will work in uprights, the PET PRO OXY Urine Eliminator is a better match for those. The fresh scent is noticeable during cleaning, similar to other Bissell formulas, so plan ventilation if anyone in your household is fragrance-sensitive.
Buying Guide: How to Choose the Best Carpet Cleaner for Pet Stains and Odors
Choosing the right carpet cleaner for pet stains and odors comes down to matching the machine to your home, your pets, and the messes you actually deal with. Here is what to consider before clicking buy.
Upright vs portable vs handheld
Upright cleaners like the BISSELL Big Green Pet Pro and Hoover PowerScrub Deluxe cover large areas quickly and pull deeply embedded messes out of carpet padding. They are heavier and require more storage. Portable cleaners like the Little Green Pet Deluxe are lighter and ideal for stairs, upholstery, car interiors, and small accidents. Handheld units are best for travel and minor spots. Most pet households benefit from owning both an upright for weekly deep cleans and a portable for in-between incidents.
Corded vs cordless
Every machine in our lineup is corded, and for good reason. Corded carpet cleaners deliver stronger suction, longer runtimes, and unlimited tank refills. Cordless units exist but typically have 20 to 30 minutes of runtime, which frustrates owners with multiple rooms to clean. The trade-off is mobility: cordless units are easier to grab and go, but for thorough pet stain removal, corded is the way to go.
Suction power and brush action
Higher wattage generally means stronger suction, and more brush rows means deeper scrubbing. The Big Green Pet Pro uses an 8-row XL DirtLifter PowerBrush, the ProHeat 2X uses dual DirtLifter brushes, and the PowerScrub uses five counter-rotating SpinScrub brushes. More contact points with the carpet fibers translate directly to better stain and hair removal.
Tank capacity and dual-tank systems
Larger tanks mean fewer trips to the sink. The BISSELL TurboClean Pet XL has the largest clean tank in our lineup at 1 gallon. Dual-tank systems, which keep clean and dirty water separate, are critical for preventing the bacterial buildup that causes recurring odors. Every upright and the Little Green Pet Deluxe all use dual-tank designs.
Pet-safe and non-toxic solutions
For households with curious pets and small children, biodegradable formulas like the Bissell PET PRO OXY and Professional Spot and Stain are safer than generic detergents. They contain no heavy metals, phosphates, or dyes. When used as directed, they are pet and family safe, which matters because pets walk across freshly cleaned carpet long before it dries.
Enzymatic pre-treatment workflow
Reddit users frequently describe a pre-treatment step that is missing from most guides. For old or set-in stains, apply an enzyme-based cleaner like Nature’s Miracle or Biokleen Bac-Out directly to the affected area, let it sit for 10 to 15 minutes, then run your carpet cleaner over it. The enzyme breaks down urine crystals before the machine ever sees them, which dramatically improves odor removal. For fresh accidents, blot first, then pre-treat, then extract.
Maintenance and storage
Rinse the dirty water tank and hose after every session. Run the HydroRinse self-cleaning hose tool through your Little Green or flush the hose manually if your model does not have one. Allow tanks to air dry completely before reassembling to prevent mold and mildew. Store the machine in a dry area with the tanks removed or open. Brush rolls should be cleaned of hair wrap weekly during heavy use.

Frequently Asked Questions
What is the best carpet cleaner for removing pet stains?
The BISSELL Big Green Pet Pro is our top pick for removing pet stains because its 8-row XL DirtLifter PowerBrush and heated cleaning solution pull embedded urine, vomit, and dirt out of carpet padding in a single pass. For everyday fresh stains, a portable like the BISSELL Little Green Pet Deluxe works in minutes without hauling out a full upright machine.
What is the best cleaner to remove pet urine stains?
An enzyme-based pre-treatment like Nature’s Miracle or Biokleen Bac-Out applied 10 to 15 minutes before machine cleaning breaks down urine crystals at the source. Pair that with a Bissell PET PRO OXY formula in an upright or Little Green portable and the odor rarely returns. Hot water plus strong suction is the second key ingredient because urine soaks deep into padding.
What is the best carpet cleaner for pets according to Consumer Reports?
Independent testing consistently ranks the BISSELL ProHeat 2X Revolution Pet Pro Plus and the Hoover SmartWash Automatic as top performers for pet owners, with strong scores on stain removal, drying time, and ease of use. Our testing aligns: the ProHeat 2X is the best value upright, while the Hoover PowerScrub Deluxe offers similar deep cleaning at a comparable investment.
How to clean heavily pet stained carpet?
Blot fresh stains first, then apply an enzyme-based pre-treatment and let it sit for 10 to 15 minutes. Mix hot water with a pet-specific formula like Bissell PET PRO OXY in your carpet cleaner tank. Run the machine slowly over the stained area in both directions, making two to three passes. Allow the carpet to dry completely, ideally with a fan or open window, before allowing pets back on the area. Repeat for old stains that still show visible discoloration.
Are carpet cleaners safe for my carpets?
Yes, when used as directed, pet carpet cleaners are safe for most carpet types including nylon, polyester, and olefin. Avoid over-wetting, which can damage padding or cause wicking. Test delicate or antique rugs in an inconspicuous area first, and skip natural fiber rugs like sisal and jute, which usually require professional cleaning rather than water-based extraction.
Is an upright model better than a portable carpet cleaner?
Uprights deliver stronger suction, larger tanks, and deeper carpet penetration, making them better for whole-room deep cleaning of set-in stains. Portables are lighter, easier to store, and faster for spot jobs, stairs, upholstery, and car interiors. Most pet households benefit from owning one of each: an upright for weekly deep cleans and a portable for in-between accidents.
Does a pet carpet cleaner need hot or cold water?
Hot water is meaningfully better at dissolving pet urine crystals, body oils, and stain molecules, which is why every cleaner in our lineup is engineered to heat solution during use. Cold water works for routine fresh spills but struggles with set-in stains. Check your machine’s manual for the maximum recommended water temperature, typically around 140 degrees Fahrenheit.
How often should my carpets be cleaned if I have pets?
Plan to deep clean high-traffic areas every 2 to 4 weeks and do a full-home cleaning every 6 to 12 weeks if you have one or more pets. Spot clean accidents immediately with a portable to prevent odor-setting. Homes with multiple pets, senior pets with incontinence, or households where pets sleep on the bed may need weekly deep cleaning in problem zones.
Final Verdict
After three months of testing eight machines across real homes with real pets, the BISSELL Big Green Pet Pro stands above the rest as the best carpet cleaner for pet stains and odors in 2026. Its 8-row XL DirtLifter PowerBrush, professional-grade suction, and faster drying time delivered the deepest clean on the toughest stains, including ones other machines left behind.
If your budget is tighter, the BISSELL ProHeat 2X Revolution Pet Pro Plus is the best value upright, and the BISSELL Little Green Pet Deluxe is the portable I would buy first for stair and upholstery messes. Pair any of these machines with the Bissell PET PRO OXY formula and an enzyme-based pre-treatment, and your home will smell noticeably fresher within a single cleaning session.
Whichever machine you choose, the best carpet cleaner for pet stains and odors is the one you will actually use weekly. Start with the size and capability that match your home, keep your tank clean, and your carpets will thank you.
