Key takeaways
- Storage: Spot cleaners fit on a closet shelf. Uprights need floor space roughly like a vacuum cleaner, and the Big Green needs a dedicated corner.
- Weight with water: Filled tanks add considerable weight. Check the maker’s listed weight and consider how you will carry it upstairs.
- Solution: Use the formula the maker lists for your machine. Unapproved soaps can foam, clog the recovery path or leave residue that attracts dirt. Pet-specific formulas from the same brand are the safe default.
- Pet safety: Keep pets off damp carpet until it is dry, store solutions out of reach, and read the label for pet-related cautions. If an animal licks or eats cleaning product, contact your veterinarian or a pet poison helpline.
- Drying: Open windows or run fans. Over-wetting can leave carpet padding damp, which risks odor and mildew.
- Old urine stains: Extraction removes liquid, but deep, set-in urine can soak into padding. Machines help, but severe cases may need an enzyme treatment or professional attention.
- Maintenance: Empty and rinse tanks after each use, clear hair from brush rolls, and let parts air dry to prevent smells.
For most pet households, a compact spot cleaner such as the Bissell Little Green or the Rug Doctor Pet handles accident cleanup best, while the Hoover PowerDash Pet suits whole-room washing on a modest budget and the Bissell Big Green Professional or a ProHeat-style upright suits large, heavily used carpet areas. The right choice depends on how much carpet you have, how often accidents happen, and how much storage and lifting you can manage.
Carpet shampooers, more accurately called carpet cleaners or extractors, spray a cleaning solution and water into the pile and pull the dirty liquid back into a recovery tank. For people with dogs and cats, that means urine, vomit, mud and drool are the daily targets. Reviewers from outlets such as HGTV, Good Housekeeping and Reviewed generally split the category into three types: portable spot cleaners, upright household machines, and heavy-duty large-format machines. This guide compares the models that appear most often in 2026 roundups and explains the trade-offs without quoting prices.

At a Glance: Carpet Cleaners Compared
| Model | Type | Best for | Reported strengths | Limits |
|---|---|---|---|---|
| Bissell Little Green (Pet Deluxe, Pro, Max versions) | Portable spot cleaner | Pet accidents, stairs, car seats, upholstery | Light and easy to store; Good Housekeeping named it best portable; Vacuum Wars reports strong stain reduction for the Pro version | Small tanks, so large areas mean many refills |
| Rug Doctor Pet Portable Spot Cleaner | Portable spot cleaner | Set-in stains and wine-type marks | HGTV named it its best portable; Yahoo’s comparison found it close to the Little Green and better on wine | Heavier when tanks are full and louder, according to Good Housekeeping |
| Hoover PowerDash Pet | Upright | Whole rooms on a budget | Widely listed as a value pet upright; makers list heated drying and an antimicrobial brush roll; roughly 12.5 pounds per roundups | Less power and capacity than premium uprights |
| Hoover SmartWash Pet Automatic | Upright, automatic | Buyers who want a simpler cleaning cycle | Good Housekeeping’s best-value pick | Bulkier to store than a spot cleaner |
| Bissell Revolution HydroSteam Pet | Upright with heated cleaning | All-round pet households | Good Housekeeping’s best overall | Larger and heavier than spot cleaners |
| Bissell ProHeat 2X Revolution Pet Pro Plus | Upright | Deep cleaning of pet-soiled carpet | Named best overall pet upright in one roundup | Premium-tier machine; takes space |
| Bissell Big Green Professional | Heavy-duty | Large homes, rental turnovers, frequent use | Favored by Reviewed and others for power | Bulky, heavy, and the priciest of the group |
Portable Spot Cleaners for Pet Accidents
If most of your mess comes from a puppy, a senior dog, or a cat that misses the litter box, a spot cleaner is usually the first thing to buy. These machines are small enough to leave in a closet and pull out within a minute of an accident, which matters because fresh messes come out far more easily than dried ones.
Bissell Little Green
The Little Green is sold in several versions, including Pet Deluxe, Pro and Max variants, and it is the machine most often named when reviewers talk about portable cleaners. HGTV picked it as the most lightweight and portable cleaner on its list. Good Housekeeping’s comparison, as reported on Yahoo, named it best portable. Vacuum Wars measured stain-reduction results and placed the Little Green Pro near the top of its spot-cleaner list, which suggests the extra tools on the Pro are not just marketing. It comes with a hose and a small tool for stairs and upholstery, which is where pets often leave their marks.
The trade-off is capacity. Small tanks mean frequent trips to the sink if you try to clean a whole hallway. Treat it as a stain-and-spot tool rather than a room cleaner.
Rug Doctor Pet Portable Spot Cleaner
The Rug Doctor Pet is the Little Green’s closest rival. HGTV named it best portable because it had more success lifting stains. Yahoo’s broader comparison found the two nearly even on soda and honey, with the Rug Doctor doing better on red wine and the Little Green clearing washable marker faster. Good Housekeeping noted that the Rug Doctor feels heavy when both tanks are full and is louder in use. If you are lifting the machine up stairs frequently, that weight matters.
Upright Carpet Cleaners for Whole Rooms
An upright cleaner is the better fit when dog hair, tracked-in mud and general traffic wear leave entire rooms looking dull. They hold more solution, cover more floor per pass and usually offer a heated or brush-driven cleaning action.
Hoover PowerDash Pet
The PowerDash Pet is the machine reviewers cite for value. Roundups describe it as light for an upright, around 12.5 pounds, and the maker lists features such as heated drying and an antimicrobial brush roll. Reviewed.com describes it as more affordable than many rivals and well suited to spot stains plus occasional large areas. It is a sensible first extractor for someone who does not want to rent a machine every few months.
Its limits are the ones you would expect at this tier: smaller tanks and less aggressive extraction than premium machines, so heavily soiled carpet may need a second pass and longer drying.
Hoover SmartWash Pet Automatic
Good Housekeeping’s best-value pick leans on automation, which helps people who are unsure how much solution to apply or how many passes to make. The automatic approach reduces the chance of over-wetting, a common reason carpets stay damp and smell musty.
Bissell Revolution HydroSteam Pet and ProHeat 2X Revolution Pet Pro Plus
These are the step-up uprights. Good Housekeeping named the HydroSteam Pet its best overall, and a pet-focused roundup chose the ProHeat 2X Revolution Pet Pro Plus as its best overall upright. Both are heavier and larger than the PowerDash, and both sit in the mid-range to premium tiers. They suit homes with several pets, or owners who expect to deep clean every few months and want strong results without renting.
Heavy-Duty: Bissell Big Green Professional
The Big Green Professional gets repeated praise from Reviewed and other outlets for raw cleaning power and for being built closer to a commercial machine. The same reviewers point out that it is bulky, heavy and more expensive than competing home models. It makes sense for large homes with wall-to-wall carpet, foster households, or anyone who would otherwise hire a professional several times a year. It is overkill for an apartment with one rug.
Fit, Size and Care Notes

Pick X If… Decision Table
| Your situation | Pick | Why |
|---|---|---|
| Puppy, senior dog or cat with occasional accidents | Bissell Little Green | Light, quick to deploy, strong spot-cleaning record |
| Stubborn set-in stains and you can handle extra weight | Rug Doctor Pet | Reviewers report good stain lifting, especially wine-type marks |
| Budget, want to clean whole rooms | Hoover PowerDash Pet | Value pick with a pet-focused brush roll |
| Want a simpler, guided cycle | Hoover SmartWash Pet Automatic | Automatic operation reduces guesswork |
| Multiple pets, regular deep cleans | Bissell HydroSteam Pet or ProHeat 2X | More capacity and cleaning action |
| Large carpeted home, heavy use | Bissell Big Green Professional | Power and capacity close to commercial class |
Budget Tiers
Budget: The Hoover PowerDash Pet and the smaller Little Green versions deliver a lot for the least outlay. Mid-range: Rug Doctor Pet, Hoover SmartWash Pet Automatic and Bissell HydroSteam Pet sit here. Premium: The ProHeat 2X Revolution Pet Pro Plus and Big Green Professional carry the highest costs and the most weight.
Many buyers end up pairing a budget upright with a small spot cleaner. That combination covers both the daily accident and the quarterly refresh without needing a premium machine.
Alternatives to Consider
- Shark StainStriker HairPro: Vacuum Wars reports it edging just ahead of the Little Green Pro in stain reduction, making it a close alternative among portable cleaners.
- Rental machines: If you only deep clean once or twice a year, renting avoids storage and maintenance. Results depend on how well you follow the rental instructions.
- Professional cleaning: Hiring a cleaner suits old, deep odors, delicate rugs, or situations where a machine would risk damage. Ask about pet-safe products.
Frequently Asked Questions
What is the difference between a carpet shampooer and a carpet cleaner?
Shampooer is an older term for machines that applied foaming detergent. Modern products are usually called carpet cleaners or extractors, and they spray solution and suck up dirty water in one pass. Look for the maker’s recommended formula rather than old-style foaming shampoo.
Is a spot cleaner enough for a house with a dog?
For occasional accidents and muddy paw prints, yes. If whole rooms need freshening, a spot cleaner means a lot of refills, so an upright such as the Hoover PowerDash Pet is more practical. Many owners keep both.
How long does carpet take to dry after cleaning?
It varies with the machine, the room’s airflow and how heavily the carpet was soaked. Makers of heated models promote faster drying, but fans and open windows help any machine. Keep pets off until the carpet is completely dry.
Can I use any cleaning solution in my machine?
It is safest to use the formula the maker lists for that model. Other detergents can create excess foam, damage internal parts or leave sticky residue. Check the manual for any warranty conditions tied to solution choice.
Will a carpet cleaner remove old pet urine odor?
It can help with fresh and moderately set stains, but urine that has soaked into the padding or subfloor may remain. Enzyme-based pet treatments, repeated cleaning or professional help may be needed. If odor persists, the padding may need to be replaced.
Which is better, the Little Green or the Rug Doctor Pet?
They are close. The Little Green is lighter and quieter, while reviewers say the Rug Doctor did better on some stains, such as wine. If you lift the machine a lot, the weight difference is likely to decide it.
