The short version: our #1 pick is the Bissell ProHeat 2X Revolution Pet Pro, and it suits a household with animals and carpet in more than one room — pet accidents soak into the pad beneath the carpet, and this pulls more liquid back out of that layer than anything else at domestic prices. If over-wetting is your failure mode, the Hoover SmartWash+ automates the dry pass and prevents it. And whatever full-size machine you buy, keep a portable like the Little Green Max Pet for accidents caught in the first ten minutes.
The most important thing on this page is not a machine, though. Urine odour lives in uric acid crystals that water extraction does not remove. Enzyme cleaner first, machine second, or the smell comes back on the first humid day. One caveat worth carrying through this whole category: EPA registers disinfectants and the product label governs what it may claim, so a cleaner disinfects only to the extent its registration and directions say it does.
Top Picks at a Glance
Our #1 Pick: Bissell ProHeat 2X Revolution Pet Pro
Understanding what a pet accident actually is changes what you should buy. A cup of liquid on carpet does not stay in the carpet. It passes through the pile, through the backing, into the foam pad underneath, and spreads outward as it goes — a visible six-inch stain on the surface is routinely a twelve-inch contaminated area in the pad. In older or repeat cases it reaches the subfloor. Anything that cleans only the pile is treating the smallest part of the problem.
The ProHeat 2X Revolution Pet Pro is the machine most consistently described in the owner-review record as recovering that lower layer. Heatwave technology keeps the water hot throughout the clean rather than letting it cool in the tank, which matters because warm water carries more soil and evaporates faster. The deep-reach pet tool is specifically shaped to pull liquid up from the pad. And the express mode dries carpet in about half an hour, which limits the window in which damp padding can start smelling.
The removable brush roll deserves a mention of its own. In a home with a shedding animal, hair wraps the brush and is the first thing to degrade performance. Being able to take it out and cut the hair off in two minutes is the difference between a machine that works for years and one that quietly gets worse.
Honest caveats: it is heavy, and awkward on stairs. It is the most expensive option here. Cleaning the unit after a pet job is a genuine chore, and skipping it leaves the machine itself smelling. And no machine, this one included, removes uric acid crystals — that is an enzyme job. EPA lists dust mites in carpets and upholstered furniture among the common asthma triggers and recommends vacuuming carpets and furniture every week.
The Ranked Field
Best for a household with animals and more than one room of carpet
- Heatwave technology keeps the water hot through the whole clean
- Express clean mode dries carpet in about 30 minutes
- Pet-specific tools including a deep-reach tool for accidents
- Removable brush roll for hair, which is the part that clogs first
Why buy it: urine soaks into the pad beneath the carpet, and this is the domestic machine that pulls the most liquid back out of that layer.
Best for anyone who over-wets carpet and then wonders why it smells
- Automatic mixing and dispensing — push forward to wash, pull back to dry
- No trigger to hold, so the dose is consistent across the room
- Wide cleaning path covers a room quickly
- Separate upholstery hose and tools included
Why buy it: the automatic dry-pass is the single best defence against the over-wetting that causes stains to wick back and odour to return.
Best for spot accidents dealt with in the first ten minutes
- Small enough to keep in a hall closet and grab immediately
- Larger tanks than the original Little Green
- Works on stairs, car seats and upholstery as well as carpet
- Tough stain tool with scrubbing bristles
Why buy it: a pet accident cleaned in ten minutes is a non-event; the same accident cleaned next weekend is a permanent odour problem.
Best for apartments, small homes and a first full-size machine
- Light and compact for a full-size cleaner — easy on stairs
- HeatForce speeds drying
- Dual-tank system keeps clean and dirty water apart
- Cheapest credible upright with a real pet tool
Why buy it: it is the least expensive way to own a proper upright extractor, and weight is the reason people actually use it.
Best for quick refreshes on high-traffic areas between deep cleans
- Under 13 lb, genuinely carryable up a staircase
- Powered brush roll with a stain trapping tool
- Small footprint for closet storage
- Uses standard Bissell formulas
Why buy it: the machines people actually use are the ones they can lift, and this is the lightest full-size option that still scrubs.
Best for the same spot, over and over, with an older or unwell animal
- Deep-reach tool designed to extract from carpet padding
- Stiffer pet stain tool for ground-in hair and dander
- Larger dirty tank for messy jobs
- Long hose for stairs and awkward corners
Why buy it: repeat accidents saturate the pad and the subfloor, and this is the tool built to pull liquid back out of that lower layer.

How We Rank
We do not buy these machines or clean carpet with them. We read the owner-review record at volume, because pet stain recovery is judged weeks later — whether the smell came back is the only question that matters, and only owners can answer it. Four things carry the weight. Extraction depth, inferred from reviewers describing odour recurrence and drying time, which is the honest proxy for how much liquid the machine recovers from the pad. Hair handling, because a wrapped brush roll degrades every other capability. Weight and deployment speed, since a machine that is a project to set up does not get used on a fresh accident. And durability, particularly pump failures in the second year. Prices were checked at the time of writing. Full method on how we rank.
The Machines, Reviewed
1. Bissell ProHeat 2X Revolution Pet Pro — Best Overall
Covered above. What owners like: that odour genuinely stays gone when the process is followed; the deep-reach tool; the removable brush roll for hair; and fast drying in express mode. Recurring complaints: weight and stair handling; the after-use cleaning routine; price; and reports of the pump failing in year two, usually in machines used with high-foam formulas. Check price.
2. Hoover SmartWash+ Automatic — Best Automatic
The automatic dispensing is a better idea than it sounds. On a conventional machine you hold a trigger to spray and release it to extract, and almost everyone sprays too much and extracts too little — which is the direct cause of over-wetting, wicking and returning odour. The SmartWash reverses the ergonomics: push forward and it washes, pull back and it dries, with no decision to make.
Across the review record, the people most positive about it are those who had previously soaked a carpet and regretted it.
Recurring complaints: it is large and awkward to store. The automatic system removes the option to concentrate solution on a bad patch. It is expensive. And several reviewers report that the mixing system needs careful rinsing to avoid clogging. Check price.
3. BISSELL Little Green Max Pet — Best Portable
Included in a full-size roundup because for pet accidents specifically, response time beats machine capability. An accident found within minutes and extracted immediately usually leaves nothing behind; the same accident discovered hours later has already reached the pad. A portable that lives in a hall closet is the machine that gets to it in time.
The Max version fixes the tank-size complaint that dogged the original, and it handles stairs, upholstery and car seats too.
Recurring complaints: it is not a room-cleaning machine and buyers expecting that are disappointed. Post-use cleaning is essential and tedious. And a large accident will fill the dirty tank. Check price.
4. Hoover PowerDash Pet Compact — Best Value Upright
The cheapest credible upright extractor with a proper pet tool, and unusually light for a full-size machine. Weight matters more than the spec sheet suggests: a heavy machine stays in the basement and a light one gets used, and used often is what actually keeps a carpet clean in a pet household.
HeatForce speeds drying, which is the second-most-important variable after extraction.
Recurring complaints: suction is noticeably weaker than the ProHeat, so carpet stays damper longer. The tanks are small for a full-size unit. And the plastic construction feels less durable, with the review record showing more second-year failures than the Bissell. Check price.
5. Bissell TurboClean PowerBrush Pet — Best Lightweight
Under thirteen pounds, which puts it in genuine carry-up-the-stairs territory, with a powered brush roll that still scrubs properly. For high-traffic areas that need a refresh between deep cleans, it is the machine most likely to be pulled out on a Tuesday evening.
Recurring complaints: it leaves carpet wetter than the larger machines, so drying takes longer and fans are advisable. The small tanks mean frequent stops on a whole room. And the hose for tools is short. It is a maintenance machine, not a rescue one. Check price.
6. BISSELL SpotClean Pet Pro 2458 — Best for Repeat Accidents
Where the same spot is being hit repeatedly — an older dog, an unwell cat, a puppy in training — the pad and sometimes the subfloor stay contaminated, and each new accident lands on old residue. The deep-reach tool on this model is built to extract from that lower layer rather than the surface, and the stiffer pet tool copes with matted hair and dander.
Recurring complaints: severe long-standing contamination is beyond any extractor — at some point the pad has to be replaced, and reviewers who reached that point say so. The machine needs thorough rinsing after pet work or it develops its own odour. And the included solution sample is a token amount. Check price.
What Owners Actually Complain About
Five themes, and four have straightforward answers.
The smell came back. Uric acid crystals in the pad, not removed by water. Enzyme cleaner, applied generously, left for hours, then extracted.
The stain reappeared as it dried. Wicking — residue in the pad travelling back up. Extract more thoroughly and dry faster with fans.
The machine smells. Dirty water left in the tank. Empty, rinse and air-dry every tank and hose after every use.
The brush stopped turning. Hair wrapped around the roll. Buy a machine with a removable brush roll if you own an animal that sheds.
The carpet got dirty faster afterwards. Detergent residue attracting soil. Finish with a plain-water pass and never use dish soap in the tank.
How to Choose a Carpet Cleaner for Pet Stains
Match the machine to the pattern of the problem. Occasional accidents, one animal, small home: a portable is enough and it will get to accidents faster than an upright ever will. Multiple rooms of carpet and a shedding animal: a full-size upright with a removable brush roll. A tendency to over-wet: the automatic machine, which removes the decision. Repeat accidents on the same spot: a deep-reach portable plus a serious enzyme routine, and a realistic conversation about replacing the pad.
Then follow the process that actually works. Blot fresh accidents with towels and body weight before anything else — you can remove most of the liquid this way in the first minute. Saturate with an enzyme cleaner and give it the hours on the label. Extract, then make two or three dry passes with no solution. Finish with a plain-water pass. Run fans and open windows until the carpet is dry through its depth, not just at the tips. And clean the machine before you put it away.

The Verdict
For a home with pets and carpet, the Bissell ProHeat 2X Revolution Pet Pro is what the owner-review record supports: the deepest extraction at domestic prices, a removable brush roll that survives shedding, and fast drying that keeps odour from returning. Add the Little Green Max Pet for immediate response, and remember that no machine removes uric acid — enzyme cleaner first, every time. Check price on Amazon →
