The short answer: For a home with pets, buy a carpet cleaner with strong suction, a powered rotating brush, heated cleaning, and a pet-specific formula. An upright deep cleaner like the BISSELL ProHeat 2X Revolution Pet Pro Plus is best for whole-room cleaning, while a portable spot cleaner like the BISSELL Little Green Pro is best for accidents on stairs, upholstery, and car seats. Most pet homes need one of each — the upright for weekly deep cleans and the portable for the accidents in between.
What Makes a Pet Carpet Cleaner Different?
Pet messes are not ordinary dirt. Urine soaks deep into carpet fibers and padding, vomit and mud dry into the pile, and pet hair weaves itself into every fiber. A regular carpet cleaner can spread a pet stain around instead of removing it, and a household vacuum cannot reach what has soaked below the surface.
A good pet carpet cleaner is built around four things: suction strong enough to pull dirty water back out of the carpet, a brush that agitates the pile to release embedded hair and dried mess, heat that helps cleaning solution break down stains, and a formula designed for pet messes — usually with enzymes or oxy action that break down the compounds causing stains and odours.
Step 1: Pick the Right Type — Upright, Portable, or Both?
Upright deep cleaners
Upright carpet cleaners are full-size machines that clean wall-to-wall carpet like an upright vacuum. They hold the most cleaning solution, cover large rooms quickly, and deliver the strongest deep-cleaning performance. If you have carpeted bedrooms or a carpeted living room and a dog, this is your main machine.
The downside is weight and storage. Uprights are heavy, take up closet space, and are awkward on stairs. They are also overkill for a single accident — you would not haul out a full-size machine for one spot on the rug.
Portable spot cleaners
Portable spot cleaners are small, handheld machines for accidents: urine spots, vomit, muddy paw prints, and stains on stairs, upholstery, and car seats. They are light, store easily, and are ready in a minute. Every pet home should own one, even if it also owns an upright.
The downside is capacity. A portable cleaner has a small tank and a narrow cleaning path, so cleaning a whole room with one would take forever. Use portables for spots and upholstery, not for deep-cleaning a living room.
The right answer for most pet homes
Buy the upright first if your home is mostly carpeted, and add a portable spot cleaner as soon as you can. If your home is mostly hard floors with a few rugs, buy the portable first and rent or borrow an upright for the occasional deep clean. Our roundup of the best carpet cleaners for pet stains compares the top models in each type side by side.
Step 2: Check Suction and Water Recovery
Suction is the most important spec on a pet carpet cleaner, and it is the hardest to compare because brands measure it differently. Instead of chasing numbers, look for these practical signs of strong suction:
- Two-tank design. Separate clean-water and dirty-water tanks keep dirty water out of the cleaning solution. Every good pet carpet cleaner has this.
- Fast dry time. The BISSELL ProHeat 2X Revolution Pet Pro Plus advertises a 30-minute dry time with its Dual DirtLifter PowerBrush — faster drying means more dirty water was recovered and less moisture was left in the carpet.
- HeatForce or heated cleaning. Heat helps solution break down dried stains and speeds drying. The Hoover PowerDash Pet uses HeatForce fast drying for the same reason.
Wet carpet that stays damp for hours is a problem: it grows mold and mildew, and the smell comes back worse than before. Strong suction and heat are what prevent that.
Step 3: Look at the Brush System
The brush does the work that suction cannot. A powered rotating brush agitates carpet fibers, loosening embedded pet hair and dried mess so the suction can lift it out. Look for:
- Dual rotating brushes. Two brushes clean better than one on pet hair and heavy traffic lanes.
- A pet-specific tool. A tough stain tool or pet upholstery tool with rubber nubs pulls hair off stairs and furniture that a flat nozzle misses.
- An antimicrobial brush roll. The Hoover PowerDash Pet has an antimicrobial brush roll that resists odour-causing bacteria — useful when the machine itself sits damp between uses.
- Self-cleaning tools. The BISSELL Little Green ProHeat Pet includes a self-cleaning tough stain tool that rinses itself after use, so you do not have to scrub pet mess out of the tool by hand.
Step 4: Choose the Right Formula
The machine matters, but the formula does the chemistry. For pet messes, look for a formula labelled for pets that mentions enzymes or oxy action. BISSELL’s Pet Pro Oxy formulas use oxy action to break down stain and odour compounds, and its Pet Pro Oxy Spot & Stain Urine Eliminator is designed specifically for urine.
Never use a non-pet formula on a pet stain and expect the smell to stay gone — ordinary carpet shampoo can mask odour temporarily while the urine compounds remain in the padding. Also, use only formula made for your machine type. Upright formulas and portable formulas are not always interchangeable, and using the wrong one can leave residue that attracts dirt.
One caution: always test a new formula on a hidden patch of carpet first. Some dyes and wool carpets react badly to oxy cleaners, and a test spot is cheaper than a bleached patch in the middle of the room.
Step 5: Size the Tanks to Your Home
Tank size decides how often you stop to refill and empty. A 0.5-gallon tank, like the one on the Hoover PowerDash Pet, suits apartments and single rooms. Larger uprights hold more and clean a whole floor without stopping, but they are heavier to carry when full.
For pet homes, a larger dirty-water tank matters more than a larger clean-water tank — pet messes produce a lot of dirty water, and stopping to empty mid-room is annoying. Dual tanks also make maintenance easier: knowing how to clean a carpet cleaner tank properly keeps the machine from smelling between uses.
Step 6: Consider Weight, Noise, and Storage
Upright pet carpet cleaners typically weigh 15–25 lb, and more when the tanks are full. If you have stairs, check the weight before buying — you will be carrying it up and down. Portable cleaners weigh far less: the BISSELL Little Green Pro is around 13.25 lb, and smaller portables are lighter still.
Noise matters if you have a nervous pet. Carpet cleaners are louder than vacuums, and some dogs and cats will hide for the duration. Run the machine on a low-traffic day, keep the pet in another room, and reward calm behaviour afterwards.
Storage matters too. Measure your closet before you buy an upright — some models are tall and will not fit under a standard shelf.

What to Avoid
- Single-tank machines. If the clean and dirty water share one tank, you are cleaning with dirty water. Skip them.
- No pet tool included. A machine without a pet upholstery or tough stain tool will struggle on stairs and furniture, where pets spend most of their time.
- Vague “pet” labelling with no enzyme or oxy formula. Marketing words are cheap; check that the included formula actually lists pet-specific stain and odour action.
- A machine too heavy to carry upstairs. The best cleaner is the one you actually use — if it lives in the garage because it is too heavy to fetch, it is not helping.
Maintenance: Keep It Clean or It Will Smell
A pet carpet cleaner that is not cleaned after use becomes a smell problem of its own. After every use, empty both tanks, rinse the dirty-water tank, run clean water through the machine, and let all parts air-dry before storage. Our guide on how to clean a carpet cleaner tank has the full routine. Replace the formula cap tightly, store the machine upright, and check the brush roll for wrapped hair monthly.
The same discipline applies to spot cleaning other messes — the technique in our guide on how to remove coffee stains from carpet works for many fresh pet stains too: blot first, never rub, then extract with the machine.

Frequently Asked Questions
What is the best carpet cleaner for pet urine?
An upright deep cleaner with heated cleaning and a pet oxy formula — such as the BISSELL ProHeat 2X Revolution Pet Pro Plus — removes urine from deep in the pile. For fresh accidents, a portable spot cleaner like the BISSELL Little Green Pro extracts the urine before it soaks into the padding.
Do I need a special formula for pet stains?
Yes. Pet formulas with enzymes or oxy action break down the compounds in urine and vomit that cause stains and odours. Ordinary carpet shampoo can mask the smell temporarily without removing the cause.
Can a carpet cleaner remove old pet stains?
It can improve them, but old, set-in urine that has reached the padding may need multiple passes, an enzyme pre-treatment, and sometimes professional cleaning. Fresh stains are far easier — extract them the same day whenever possible.
How often should I deep-clean carpets with pets?
Every 3–6 months for high-traffic rooms, plus spot cleaning accidents as they happen. Homes with multiple pets or allergy sufferers should deep-clean quarterly.
Are carpet cleaners safe for wool carpets?
Check the label first. Some oxy and enzyme formulas are not safe for wool. Test any new formula on a hidden patch, and use the gentlest setting on delicate fibers.
Upright or portable — which should I buy first?
If your home is mostly carpeted, buy the upright first. If you have mostly hard floors with a few rugs, buy the portable first. Most pet homes end up owning both, so treat the first purchase as the start of a pair.
Final Verdict
Choosing a carpet cleaner for pets comes down to matching the machine to your home: an upright deep cleaner with heat, strong suction, and a pet formula for carpeted rooms, plus a portable spot cleaner for accidents on stairs, upholstery, and car seats. Prioritize two tanks, a powered brush, a pet-specific tool, and a formula with enzyme or oxy action. If you need a single recommendation, start with the BISSELL ProHeat 2X Revolution Pet Pro Plus for whole-room cleaning and add a BISSELL Little Green Pro for spot duty — that pair covers nearly every pet mess a home can produce.
