Which Carpet Cleaner Actually Lifts Old Stains?
The Bissell ProHeat 2X Revolution Pet Pro is our top pick for strong suction and pet-focused tools. The Hoover PowerDash Pet is the lightweight value choice, while the Bissell Little Green handles portable spot jobs best.
Homes with kids, pets or high-traffic carpet need a machine that reaches dirt a vacuum leaves behind. The Bissell ProHeat 2X Revolution Pet Pro handles that job first, with the Hoover PowerDash Pet and the portable Bissell Little Green close behind for lighter tasks.
A carpet cleaner can look powerful on paper yet still soak carpets or skip set-in stains entirely. We compared suction and brush design, tank size, weight and drying speed using published specifications, then weighed those against what owners report after months of real use.
The shortlist, ranked
Bissell ProHeat 2X Revolution Pet Pro
Dual DirtLifter brush rolls pair with strong suction and a heated cleaning mode to loosen tough, ground-in stains. Separate clean and dirty water tanks keep the process hygienic throughout a full room. Pet owners rely on the dedicated stain tools for accidents on heavy-traffic carpet.
Pros
- Strong suction and deep cleaning
- Great pet stain tools
- Two-tank system stays hygienic
Cons
- Heavy to carry on stairs
- Bulky to store
Hoover PowerDash Pet
A dual-tank design and spinning HeatForce brush system fit inside a compact, lightweight upright built for pet messes. Maneuvering around furniture and storing it in a closet takes little effort. Smaller homes and quick clean-ups suit this model especially well.
Pros
- Lightweight and easy to steer
- Good value price
- Dries fairly quickly
Cons
- Smaller tanks need refilling
- Less power on deep stains
Bissell Little Green Portable
Sudden spills, car seats and stairs call for a compact machine, and the Little Green pulls strongly for its size. A scrubbing nozzle handles upholstery and tight corners a full-size upright cannot reach. Whole rooms are outside its scope, but for isolated messes it performs well.
Pros
- Excellent for spots and upholstery
- Compact and portable
- Strong suction for its size
Cons
- Not for full rooms
- Manual scrubbing required
Bissell CrossWave Cordless Max
Vacuuming and washing happen in one pass, which suits sealed hard floors as well as area rugs and low-pile carpet. Cordless operation and a self-cleaning cycle add convenience between deeper cleans. Deep carpet restoration still calls for a dedicated upright instead.
Pros
- Cleans floors and rugs
- Cordless convenience
- Self-cleaning brush cycle
Cons
- Not for deep carpet cleaning
- Battery limits run time
Hoover SmartWash Automatic
Mixing and dispensing solution happens automatically, so a push forward pass cleans and a pull back pass dries. Beginners avoid the usual guesswork around solution ratios entirely. Full rooms get even coverage, though the machine itself is large to store between uses.
Pros
- Very easy automatic operation
- Good full-room coverage
- Even drying passes
Cons
- Large and heavy
- Uses solution quickly
Bissell SpotClean Pro
A longer hose and bigger tanks than the Little Green give this portable more reach across stairs, upholstery and car interiors. Heated trigger tools add cleaning strength for frequent spot jobs. Bulk increases over the smaller model, but so does capacity per fill.
Pros
- Long hose and bigger tanks
- Powerful for spots
- Great for cars and stairs
Cons
- Bulkier than the Little Green
- Not for whole rooms
Rug Doctor Deep Carpet Cleaner
Vibrating dual brushes and rental-grade suction restore neglected or heavily soiled carpet that lighter machines cannot touch. Durability holds up under repeated heavy use across large rooms. Weight and drying time both run higher than other picks here, which limits it to occasional deep cleans.
Pros
- Very strong deep-cleaning power
- Durable build
- Large tank for big jobs
Cons
- Heavy and bulky
- Longer drying time
What matters most
Deep cleaner or spot cleaner: which job needs which machine? Full-size uprights like the Bissell ProHeat and Rug Doctor deep-clean entire rooms and restore heavily soiled carpet. Portables like the Little Green instead target spills, stairs and upholstery. Many households own both, running an upright for periodic deep cleans and a portable for accidents in between.
What actually generates cleaning power Suction, brush action and warm water combine to determine how much dirt a machine lifts. Dual rotating or vibrating brushes agitate carpet fibers, while stronger suction pulls more water and grime back out, which speeds drying too. Heated modes help dissolve grease and pet stains, though the water gets warmed rather than truly heated.
Why tanks, weight and drying time all connect Two-tank systems keep clean and dirty water separate, so grime never gets spread back onto the carpet. Bigger tanks mean fewer refills but add weight, which matters when carrying a machine up stairs. Strong suction leaves carpets damp instead of soaked, and owners report machines that dry within a few hours avoid musty smells.
Choosing pet-specific tools and staying on top of maintenance Households with animals should look for pet-specific tools, tough stain modes and odor-focused formulas, as offered on the Pet Pro and PowerDash Pet. Whatever machine you buy, rinse the tanks and clean the brush roll after every use. Leftover water and hair breed odors and shorten a machine’s working life.

Common questions
Is a carpet cleaner better than steam cleaning for carpet?
Carpet cleaners inject a water and detergent solution, agitate with brushes, then extract the mixture, which lifts embedded grime effectively. True steam cleaners rely on hot vapor and suit sanitizing hard surfaces better. For carpet specifically, an extraction machine does more work.
How often should I deep clean my carpet?
Most homes benefit from a deep clean every 6 to 12 months, and more frequently with pets, kids or allergies present. Spot cleaning spills immediately, combined with regular vacuuming, keeps carpets fresher between deep cleans.
Do I need a separate carpet cleaner just for pet stains?
Not necessarily, though pet-focused models like the Bissell Pet Pro and Hoover PowerDash Pet add tools and formulas aimed at odors and set-in accidents. A good portable spot cleaner handles occasional pet messes just fine.
How long does carpet take to dry after cleaning?
Machines with strong suction typically leave carpet dry within 2 to 6 hours, depending on airflow and how much water was used. Opening windows and running fans speeds drying and helps prevent musty odors from setting in.
Can a carpet cleaner be used on upholstery?
Yes, most models include a hose attachment built for upholstery, and portables like the Little Green excel at it. Always check the furniture’s cleaning code first, then test a hidden area before treating the whole piece.
What separates a portable cleaner from an upright?
Uprights are large machines built for cleaning entire rooms and deep-soiled carpet. Portables are compact units meant for spots, stairs, upholstery and car interiors. Many households keep one of each for different jobs.
Do carpet cleaners work on high-traffic hallway stains?
Machines combining strong suction, dual brushes and a slow cleaning pass remove most high-traffic grime in one or two passes. Very old or set-in stains sometimes need a repeat pass or a dedicated pre-treatment solution.
How should I maintain a carpet cleaner between uses?
Empty and rinse both tanks after every use, then clean hair and debris from the brush roll before storage. Letting parts air dry fully prevents odors, mold and clogs, keeping the machine performing well for years.
Our pick
For homes needing genuine deep-cleaning power, the Bissell ProHeat 2X Revolution Pet Pro remains our top recommendation thanks to its suction and dedicated pet tools.
