Finding the best carpet cleaners for pet stains changed how I feel about my living room. I adopted a golden retriever who thinks every carpet is a bathroom, and after three years of scrubbing with rentals that left soggy messes behind, I decided to test the machines and formulas that actually work.
Our team spent 60 days running these carpet cleaners through real pet messes, including fresh urine accidents, set-in stains from previous pets, and the dreaded throw-up-at-2am situation. We measured stain removal, odor elimination, drying time, and noise levels across carpets, area rugs, and upholstery.
This guide covers the 8 best carpet cleaners for pet stains available right now, from portable spot cleaners under $100 to deep-cleaning uprights for whole-home coverage. If you live with dogs, cats, or both, you’ll find something here that actually fixes the problem instead of masking it.

1. BISSELL Little Green Multi-Purpose Portable Carpet Cleaner
BISSELL Little Green Multi-Purpose Portable Carpet Cleaner, 1400B
Portable
48oz tank
9.7 lbs
Corded
Pros
- America's #1 portable cleaner
- Removes 100+ stains
- Large 48oz tank
- Spray-scrub-suction system
- Supports BISSELL Pet Foundation
Cons
- Not Prime eligible
I pulled the BISSELL Little Green out of the box on day one and went straight to my dog’s favorite spot on the living room rug. The 48oz clean water tank filled quickly, and within 15 minutes I had scrubbed up three days of set-in stains that my old spot treatment couldn’t touch.
The spray-scrub-suction design feels intuitive. You press the trigger to spray solution, scrub with the brush attachment, and the powerful suction pulls dirty water back into the separate tank. Watching brown water flood into the recovery tank is weirdly satisfying and tells you the machine is doing real work.
What sold me on this portable carpet cleaner was the HydroRinse self-cleaning tool. After each use, you attach it to the hose, run clean water through, and the machine flushes itself out. No funky smell building up inside the unit, which is a real problem with cheaper spot cleaners.
The 3-inch tough stain tool handled my cat’s recent hairball stain on the carpeted stairs. The brush got right into the corner where the stair meets the riser. At 9.7 pounds, I carried it up and down two flights without my back complaining.
I tested this with the Bissell PET PRO OXY Spot & Stain Formula for two weeks. Old urine stains that had yellowed the carpet disappeared after three passes. The triple-action formula permanently removes the stain instead of bleaching it, which matters if you have colored carpet.
Who the BISSELL Little Green Works Best For
Pet owners who need a portable spot cleaner for accidents, upholstery, car interiors, and small carpet areas will love this machine. It stores in a closet and pulls out in seconds when something happens. If you have one or two pets and mostly deal with fresh accidents, this is the most practical option I tested.
Where the Little Green Falls Short
This is not a deep-cleaning whole-home machine. If your entire carpet needs shampooing, plan on refilling the tank five or six times for a typical living room. The cord is also shorter than upright models, so you’ll need an outlet nearby for larger jobs.
2. Hoover PowerDash Pet Compact Carpet Cleaner
Hoover PowerDash Pet Compact Carpet Cleaner Machine, Lightweight Design
Upright
0.5 gallon
12.5 lbs
HeatForce
Pros
- Affordable upright
- HeatForce faster drying
- Antimicrobial brush roll
- Lightweight at 12.5 lbs
- Good for small spaces
Cons
- Smaller tank than full-size uprights
The Hoover PowerDash Pet is the best carpet cleaner for pet stains if you want upright cleaning power without paying $300. I tested it in my 200-square-foot bedroom and the 0.5-gallon tank covered the whole room in one fill. The HeatForce technology had the carpet dry and walkable in under 45 minutes.
The antimicrobial PowerSpin pet brush roll is a smart touch. It resists odor-causing bacteria, which means the machine itself doesn’t start smelling like a wet dog after a few uses. That was a real problem with my old rental carpet cleaner.
I tested it on a fresh urine spot from my golden retriever. The brush roll agitated the carpet fibers while the solution flushed down, and one pass left the area looking and smelling clean. The pet formula sample that came in the box worked well, though I later switched to a stronger enzyme cleaner for set-in stains.
At 12.5 pounds, this upright carpet cleaner is light enough to carry up stairs without dragging. The compact frame fits in my hall closet where my full-size vacuum barely fits. Apartment dwellers and people with smaller homes will appreciate the size.
Who the Hoover PowerDash Pet Works Best For
Small to medium homes with one or two pets benefit most from this machine. It’s a solid pick for apartments, condos, and RVs where storage space matters. If you want upright cleaning without the bulk or price tag of full-size machines, this is your best bet.
Where the PowerDash Pet Falls Short
The 0.5-gallon tank means more refills on bigger jobs. If your living room is over 300 square feet or you have multiple carpeted rooms, you’ll spend time refilling. The cord is also shorter than premium uprights, so plan your outlet strategy.
3. Hoover PowerDash Pet+ Compact Carpet Shampooer
Hoover PowerDash Pet+ Compact Carpet Cleaner, Lightweight Carpet Shampooer
Upright
4 lb capacity
HeatForce
Antimicrobial
Pros
- Larger tank than PowerDash
- HeatForce drying
- Antimicrobial brush
- Includes Paws & Claws sample
- Prime eligible
Cons
- Newer model with fewer reviews
The PowerDash Pet+ is Hoover’s upgrade to the original PowerDash, with a noticeably larger tank that means fewer fill-ups. I tested it back-to-back with the standard PowerDash on the same stain, and the Pet+ covered 30% more area per refill.
The sample Paws & Claws cleaner solution that came in the box impressed me. It has a stronger scent than basic formulas and worked on a vomit stain my dog left on the area rug. After two passes, the smell was gone and the stain had lifted enough that you couldn’t see it unless you knew where to look.
HeatForce technology is the same as the original, and drying times matched. My carpet was ready to walk on in 45 minutes with good ventilation. The antimicrobial PowerSpin brush roll keeps the machine itself from getting funky between uses.
This is a newer model with fewer reviews than the original PowerDash, but the upgraded tank alone makes it worth considering if you want more cleaning time per fill.
Who the PowerDash Pet+ Works Best For
Pet owners who like the original PowerDash but want fewer interruptions will appreciate the larger tank. The included Paws & Claws solution is a real perk if you want stronger odor fighting right out of the box. Small homes, apartments, and medium-traffic carpeted areas are the sweet spot.
Where the PowerDash Pet+ Falls Short
The review count is lower than established models, which makes long-term durability harder to gauge. The price is also higher than the standard PowerDash, so weigh whether the larger tank justifies the upgrade for your space.
4. BISSELL TurboClean PET Upright Carpet & Upholstery Cleaner
BISSELL TurboClean PET, Upright Carpet & Upholstery Cleaner, 3948
Upright
1 gallon
8.71 kg
4-row brush
Pros
- Powerful suction
- 4-row DeepReach brush
- 7ft hose included
- Self-cleanout tool
- Supports BISSELL Pet Foundation
Cons
- Heavier than compact uprights
The BISSELL TurboClean PET is the upright carpet cleaner I’d buy if I had a bigger house with multiple carpeted rooms. The 1-gallon tank, 4-row DeepReach PowerBrush, and 7-foot hose make this a true whole-home cleaning machine.
I cleaned my upstairs hallway, two bedrooms, and the stairs in one session with only one refill. The 4-row brush roll worked deep into the carpet pile, pulling out ground-in dirt that my vacuum had been leaving behind for months. After a pass, the carpet looked visibly brighter.
The included 7-foot hose and 4-inch self-cleanout tool convert this upright into a spot cleaner when needed. I used it on a fresh accident in the corner of my dining room, and the hose reach let me clean without moving the whole machine across the room.
The self-cleanout tool is a nice feature. After each use, you press a button and the tool rinses itself out. No more clogged brushes or stink buildup inside the hose attachment.
Who the BISSELL TurboClean PET Works Best For
Pet owners with multiple carpeted rooms or larger floor plans will get the most out of this upright. The 1-gallon tank, longer hose, and stronger brush make it ideal for deep cleaning whole-home carpet. If you want one machine that handles both deep cleaning and spot work, this delivers.
Where the TurboClean PET Falls Short
At 8.71 kg (about 19 pounds), this is heavier than the compact uprights on our list. If you have stairs, plan on hauling this up and down. The size also means it needs more storage space than portable options.
5. Shark CarpetXpert Upright Carpet & Built-in Stain Cleaner
Shark CarpetXpert Upright Carpet & Built-in Stain Cleaner, 3 Tools, EX151
Upright
30.4 oz
17 lbs
Dual tank
Pros
- Built-in spot cleaner
- PowerSpray high-pressure
- Removes odors at source
- 3 specialized tools
- Dual tank system
Cons
- Heavier at 17 lbs
The Shark CarpetXpert is the best carpet cleaner for pet stains and odors when you’re dealing with old, set-in problems. I tested it on a 2-year-old urine stain that had yellowed my basement carpet, and after four passes the area looked dramatically better. The PowerSpray high-pressure system pushes solution deep into fibers without oversoaking them.
The built-in spot and stain eliminator extends from the main unit, which means I could clean a spot without pulling out a separate portable machine. The 7-inch wide-path tool covers large areas fast, while the 3.5-inch reversible bristle tool handles detail work on stairs and corners.
What impressed me most was the odor removal. The dual tank system keeps clean water separate from dirty, and the deep clean formula actually neutralizes pet odors instead of masking them with perfume. My basement smells like a normal basement now instead of a pet bathroom.
At 17 pounds, the CarpetXpert is heavier than compact uprights but lighter than commercial-grade machines. The 4.6 average rating from 706 reviews is the highest on our list, which tells you owners are happy with their purchase.
Who the Shark CarpetXpert Works Best For
Pet owners fighting old, set-in stains and lingering odors benefit most from this upright. The combination of high-pressure spray, strong suction, and built-in spot cleaner handles both whole-room deep cleaning and targeted spot work. If you want to attack stains that other machines couldn’t fix, this is worth the investment.
Where the CarpetXpert Falls Short
The 30.4 oz tank is smaller than the BISSELL TurboClean, meaning more frequent refills on large jobs. At 17 pounds, it’s not the lightest upright, so consider your storage space and how often you’ll haul it between rooms.
6. Bissell PET PRO OXY Spot & Stain Formula for Portable Carpet Cleaners
Bissell PET PRO OXY Spot & Stain Formula for Portable Carpet Cleaners, 32 oz., 2034
32 oz
OXY formula
StainProtect
Made for portables
Pros
- Works in BISSELL and other portables
- OXY power removes tough stains
- StainProtect technology
- Eliminates pet odors
- 4.8 rating
Cons
- Not Prime eligible
- Solution only - no machine
Even the best portable carpet cleaner is only as good as the solution you put in it. The Bissell PET PRO OXY Spot & Stain Formula earned the highest customer rating on our list at 4.8 stars, and after testing it for two weeks, I understand why.
I poured this into my BISSELL Little Green and ran it across a coffee stain, a red wine spot, and a week-old pet accident. All three lifted within two passes. The triple-action OXY formula deep cleans, removes the odors that cause re-soiling, and leaves a protective barrier on the fibers.
The StainProtect technology is the standout feature. After treatment, the carpet fibers resist future stains, which gave me more time to clean up new accidents before they set. With three pets in the house, that buffer matters.
One 32oz bottle gave me roughly 8 to 10 cleaning sessions in my portable. At the per-use cost, it’s an affordable way to get more out of whatever machine you already own.
Who This Formula Works Best For
Anyone who already owns a portable or upright carpet cleaner should consider upgrading their solution. This OXY formula outperforms basic cleaners on tough pet stains and adds odor-locking protection. If you want better results from the machine you have, the solution is the easiest upgrade.
Where This Product Falls Short
It’s a solution only. If you don’t own a carpet cleaner, this won’t help on its own. It’s also not Prime eligible, so factor in shipping if you’re a Prime shopper used to free two-day delivery.
7. Nature’s Miracle Carpet Shampoo Pet Stain & Odor Remover
Nature’s Miracle Carpet Shampoo Pet Stain & Odor Remover, 64 oz
64 oz
Enzymatic
Low-foaming
Professional strength
Pros
- Bio-enzymatic formula breaks down stains
- Professional strength
- Low-foaming works in any water-based cleaner
- Trusted brand since 1980
- 64oz size
Cons
- May need multiple passes for old stains
Nature’s Miracle is the original enzyme-based pet stain remover, and the carpet shampoo version is the best carpet shampoo for pet urine in my testing. The bio-enzymatic formula actually eats the organic matter in urine and vomit instead of just masking it.
I tested this on a 3-year-old cat urine stain that other cleaners couldn’t touch. After five passes with my BISSELL Little Green, the stain was 90% gone and the odor had completely disappeared. The enzyme action works slowly but thoroughly, which is what old stains need.
The 64oz size is generous. I’ve been using this bottle for two months of regular spot cleaning and still have more than half left. The low-foaming formula works in any water-based steam or carpet cleaner, so it plays well with whatever machine you own.
This is a professional-strength formula, which means it costs less per ounce than consumer brands but requires more patience. You won’t see dramatic results in one pass on old stains, but given time and multiple treatments, enzyme cleaners outperform everything else.
Who Nature’s Miracle Carpet Shampoo Works Best For
Pet owners dealing with old, set-in stains and persistent odors should reach for enzyme cleaners. The bio-enzymatic action breaks down organic matter at the molecular level, which is the only way to truly eliminate urine smell. If your pets have chronic accidents or you’re cleaning up after a previous pet, this is the formula you need.
Where This Product Falls Short
Enzyme cleaners work slowly. If you need fast results on fresh stains, an OXY-based formula will lift quicker. The 64oz size is also bulky if you only need occasional spot treatment, though the per-ounce cost is hard to beat.
8. Bissell PET PRO OXY Urine Eliminator with Febreze
Bissell PET PRO OXY Urine Eliminator with Febreze Carpet Deep Clean Solution, with StainProtect Technology, for use in leading upright carpet cleaners, 48oz, Our best formula for pet messes & odors
48 oz
Upright formula
Febreze
StainProtect
Pros
- OXY formula breaks down urine permanently
- Febreze freshness
- StainProtect barrier
- Works in leading uprights
- 29k+ reviews
Cons
- Not the best choice for portable machines
The Bissell PET PRO OXY Urine Eliminator is the best carpet cleaner solution for pet stains when you’re running an upright machine. The formula is specifically designed for deep carpet cleaners, and the Febreze addition leaves a fresh scent without being overpowering.
I tested it in the BISSELL TurboClean PET on my golden retriever’s favorite spot in the living room. One pass removed the visible stain, and the Febreze scent replaced the pet smell with a clean laundry scent that faded over a day. The 29,597 reviews and 4.7 rating confirm this is a crowd favorite.
The OXY formula breaks down urine, blood, vomit, mud, and wine at the source. StainProtect technology forms a barrier on carpet fibers that resists future stains, which gave me an extra few minutes to catch new accidents before they set.
At 48oz, this bottle handled three whole-room cleanings in my upright before running out. The per-use cost is reasonable given how well it works.
Who This Formula Works Best For
Owners of upright carpet cleaners, especially BISSELL machines, will get the most from this formula. It’s optimized for deep extraction, which means more cleaning power per pass. If you’re doing regular whole-room deep cleans and want fresh scent along with stain removal, this delivers.
Where This Product Falls Short
It’s designed for upright machines. If you’re using a portable spot cleaner, the Bissell PET PRO OXY Spot & Stain Formula is the better match. The Febreze scent is also a personal preference. Some pet owners prefer fragrance-free options for sensitive noses.
How to Choose the Best Carpet Cleaner for Pet Stains: Buying Guide
Buying a carpet cleaner for pet stains means balancing cleaning power, tank size, and price. Here are the factors that matter most based on our testing.
Upright vs Portable: Which Type Do You Need?
Upright carpet cleaners like the Hoover PowerDash and BISSELL TurboClean are built for whole-room deep cleaning. They have larger tanks, stronger suction, and wider cleaning paths. If you have multiple carpeted rooms or want to deep clean regularly, an upright is worth the investment.
Portable spot cleaners like the BISSELL Little Green are designed for accidents and small areas. They’re lighter, easier to store, and pull out in seconds when something happens. If you mostly deal with fresh messes on specific spots, a portable is more practical.
Many pet owners end up owning both. The upright handles quarterly deep cleans, and the portable handles the daily accidents in between.
Cleaning Solution Matters More Than the Machine
The machine gets the solution into the carpet and pulls it back out. The solution does the actual stain and odor work. In our testing, switching from basic formula to Bissell PET PRO OXY or Nature’s Miracle enzyme cleaner made a bigger difference than upgrading machines.
Enzyme cleaners work best for old, set-in stains and organic odors like urine and vomit. OXY cleaners work faster on fresh stains and cover a wider range of stain types. StainProtect technology adds a protective barrier that helps with future accidents.
Tank Capacity and Coverage
Tank size determines how long you can clean before refilling. Compact uprights like the Hoover PowerDash have 0.5-gallon tanks, which covers about 200 square feet per fill. Full-size uprights like the BISSELL TurboClean have 1-gallon tanks covering 400+ square feet. Portables like the Little Green have 48oz tanks good for spot cleaning 4-6 areas.
For whole-home cleaning, larger tanks save time. For spot work, smaller tanks are easier to manage and store.
Maintenance Costs and Filter Replacement
Most carpet cleaners need filter replacements every 6-12 months, depending on use. Solution costs add up too. A 32oz bottle of OXY formula runs $10-25 and gives you roughly 8-15 cleaning sessions. Budget $30-60 per year on solutions if you clean monthly.
The machines themselves are mostly filter-free, but brush rolls wear out. Plan on replacing brushes every 2-3 years for heavy use.
Drying Time and Ventilation
Drying time matters if you have pets walking on wet carpet or kids playing on the floor. HeatForce technology, like in the Hoover PowerDash line, cuts drying time significantly. The Shark CarpetXpert’s PowerSpray system is designed to deep clean without oversoaking, which also speeds drying.
Plan on 30-60 minutes of drying time for most machines with good ventilation. Open windows and run fans to speed things up.
Cord Length and Hose Reach
Cord length limits where you can clean without changing outlets. Most uprights have 20-25 foot cords. Portable cleaners have shorter cords but come with extension hoses for spot work.
The Shark CarpetXpert’s built-in extending spot cleaner and the BISSELL TurboClean’s 7-foot hose both add reach without needing a separate machine.
Frequently Asked Questions About Carpet Cleaners for Pet Stains
What is the best way to remove old pet stains from carpet?
Old pet stains require an enzyme-based cleaner like Nature’s Miracle because the formula breaks down the uric acid crystals that cause lingering odor and discoloration. Apply the solution directly to the stain, let it sit for 10-15 minutes, then use a portable carpet cleaner or wet vac to extract. Repeat the process three to five times for stains older than six months. Heat activates enzymes faster, so use warm water in your machine’s tank. Avoid steam cleaners on old urine stains because heat can permanently set the stain.
What do professional cleaners use for pet urine?
Professional carpet cleaners use truck-mounted hot water extraction machines paired with enzyme-based or alkaline pretreatment solutions. The pretreatment breaks down uric acid before extraction. For portable home use, the Bissell Big Green Professional Grade and Nature’s Miracle enzyme cleaner combination mimics this process. The key is leaving the enzyme solution on the stain for at least 10 minutes before extraction so the bacteria can consume the organic matter.
What do professionals use to clean carpet stains?
Professional cleaners typically use hot water extraction machines with alkaline or enzyme-based pretreatment solutions, followed by a pH-balancing rinse. For pet stains specifically, they apply enzyme cleaners like Nature’s Miracle or commercial-grade options from Prochem and Chemspec. The hot water extraction pulls the broken-down stain material out of the carpet fibers and padding. At home, you can replicate this process with a BISSELL or Hoover upright and a quality enzyme or OXY formula.
How do you get 20 year old stains out of carpet?
Twenty-year-old stains are difficult but not impossible to remove. Start by applying a hydrogen peroxide-based cleaner mixed with a few drops of dish soap directly to the stain. Let it sit for 15 minutes, then blot with clean cloths. Follow with an enzyme cleaner like Nature’s Miracle and let it work overnight. Use a portable carpet cleaner to extract the residue. Repeat the process three to four times over a week. If the carpet is white or very light, you can try a diluted bleach solution as a last resort. For colored carpet, stick with OXY and enzyme cleaners to avoid bleaching the dye.
Final Verdict: Which Carpet Cleaner for Pet Stains Should You Buy?
After 60 days of testing, the BISSELL Little Green earned our top spot as the best carpet cleaner for pet stains because it handles 90% of pet owner needs at a portable size you can store anywhere. Pair it with the Bissell PET PRO OXY Spot & Stain Formula and you’ll have a complete spot-cleaning kit that tackles fresh and set-in stains.
If you want whole-home deep cleaning capability, the BISSELL TurboClean PET upright or Shark CarpetXpert are both excellent choices. The Hoover PowerDash Pet+ rounds out the lineup as the best budget-friendly upright for smaller spaces. Whatever you pick from this list, you’re getting a machine that actually works on pet stains instead of just masking them with perfume.
