Rug Doctor and Bissell dominate the home carpet cleaner market, but their approaches are fundamentally different. Rug Doctor built its reputation on rental machines found in grocery stores and hardware stores. Bissell focuses on consumer-owned machines with professional-grade features.
Which one fits your home? That depends on cleaning needs, budget, and how often you plan to deep clean. We tested machines from both brands on embedded dirt, pet stains, and high-traffic areas to find out.

Design and Build Quality
Rug Doctor Deep Carpet Cleaner
Rug Doctor’s Deep Carpet Cleaner brings commercial design thinking to home use. At 18 lbs, it balances weight and maneuverability well. The 10.5-inch cleaning path covers ground quickly, with dual cross-action brushes providing agitation on both forward and backward passes.
Build quality feels utilitarian. The 1-gallon tank works fine but needs frequent refills during whole-house cleaning. Twenty-foot cord, 12-foot hose. Reasonable reach, though open floor plans may need an outlet change.
Fair warning: Rug Doctor has discontinued this model. Remaining inventory exists, but parts availability and warranty support may become limited compared to current Bissell products.
Bissell Big Green Professional 86T3
Bissell’s Big Green is a beast. At 42 lbs, it dwarfs consumer carpet cleaners and approaches commercial rental machine territory. That weight comes from larger tanks (1.75 gallons each for clean and dirty water), a more powerful motor, and heavy-duty construction.
Six rows of DirtLifter PowerBrushes provide more agitation than typical consumer machines. Eighty-five inches of water lift suction extracts more moisture, meaning faster drying times. HeatForce technology speeds drying even further.
Five-year warranty. That says something about Bissell’s confidence. Just make sure you have storage space; this machine demands serious closet or garage real estate.
Bissell ProHeat 2X Revolution Pet Pro 1986
ProHeat 2X Revolution Pet Pro targets pet owners specifically. At 18 lbs, it matches the Rug Doctor Deep for maneuverability while adding pet-focused features. The CleanShot pretreater applies concentrated solution directly to tough stains before the main clean.
HeatWave Technology keeps water temperature consistent throughout the cleaning cycle, which really helps on greasy or oily stains. Dual DirtLifter PowerBrushes provide thorough agitation without being aggressive on carpet fibers.
For pet households, this is the most practical choice. Included pet tools, specialized cleaning formulas, and a 5-year warranty for a machine that’ll see heavy use.
Performance Comparison
Deep Cleaning Power
Deep carpet cleaning requires three things: agitation, solution application, and extraction. Both brands deliver on the fundamentals, but with different emphases.
Rug Doctor uses dual cross-action brushes rotating in opposing directions, agitating carpet fibers from multiple angles to loosen embedded dirt. The 10-amp motor provides adequate extraction, though drying times averaged 6 to 8 hours in our tests.
Big Green takes extraction far more seriously. Eighty-five inches of water lift exceeds the Rug Doctor significantly. In side-by-side testing on identical stains, the Big Green removed more water per pass and carpets dried in 4 to 6 hours. That’s a meaningful improvement if you need quick turnaround.
ProHeat 2X Pet Pro falls between the two on extraction power. Its 12-amp motor and dual brushes clean thoroughly, but the smaller tank means more refills. HeatWave Technology compensates by keeping solution at optimal temperature throughout.
Pet Stain and Odor Removal
Pet stains need enzymes to break down the organic compounds causing odors. Both brands offer pet-specific cleaning formulas, but Bissell’s pet-focused machines integrate stain pretreatment directly into the cleaning process.
Rug Doctor’s Pet Portable Spot Cleaner tackles pet accidents with a motorized brush and antimicrobial surfaces. Its 4.5-inch cleaning path targets spots rather than entire rooms. Good as a complement to a full-size machine for occasional accidents.
Bissell’s ProHeat 2X Pet Pro includes CleanShot pretreater technology. Hit a button on the handle, concentrated solution dispenses directly onto the stain. Brief dwell time, then the machine agitates and extracts. Works on both fresh accidents and set-in stains you didn’t catch in time.
For deep-seated pet odors, the Big Green’s superior extraction pulls out more moisture and dissolved contaminants. But at 42 lbs, it’s impractical for frequent spot cleaning.
Ease of Use and Maintenance
Carpet cleaners need more maintenance than vacuums. Tanks to fill and empty. Brushes to clean. Filters to rinse.
Rug Doctor keeps operation simple. Fill with hot water and solution, empty dirty water when full. Rotating brushes are accessible for cleaning, though hair and debris accumulate around the brush axles over time.
Big Green follows the same workflow with larger capacity. Those 1.75-gallon tanks cut refill frequency significantly, but at 42 lbs, carrying it up stairs isn’t fun. The retractable handle helps with storage. Still, this is not a portable machine.
ProHeat 2X Pet Pro hits a good balance. At 18 lbs, one person can carry it between floors. Clean and dirty water tanks separate for easy filling and emptying, and the included upholstery tool attaches to the 8-foot hose for furniture and stair cleaning.
Value and Pricing
Rug Doctor sits at a mid-range price point, but as a discontinued model, availability varies. Parts and service may get harder to find as inventory depletes.
Big Green costs more upfront but delivers rental-machine performance without rental fees. If you deep clean quarterly, it pays for itself within 2 to 3 years versus renting a Rug Doctor each time.
For pet owners who need regular cleaning, the ProHeat 2X Pet Pro offers the best value. Strong performance, pet-focused features, and a 5-year warranty make it a solid investment for multi-pet households.
On a tight budget? The Bissell TurboClean PowerBrush Pet 2085 is the entry-level option. It lacks heated drying and some premium features but delivers basic carpet cleaning at an accessible price.

The Bottom Line
Bissell wins this comparison for most buyers. Current product availability, strong warranties, and a diverse product range make it the more practical choice.
Big Green Professional 86T3 delivers exceptional deep cleaning for large homes and frequent cleaners. ProHeat 2X Revolution Pet Pro 1986 offers the best combination of pet-focused features and everyday usability.
Rug Doctor’s legacy products perform well but face availability challenges. For spot cleaning, the Pet Portable remains solid for pet owners who already have a full-size machine.

Frequently Asked Questions
- Is Rug Doctor better than Bissell for deep cleaning?
- Both brands offer excellent deep cleaning performance. The Bissell Big Green Professional matches Rug Doctor rental machines in cleaning power with its 6-row DirtLifter PowerBrushes and 85 inches of water lift suction. For home ownership, Bissell offers better warranty coverage (5 years vs 1 year for Rug Doctor) and easier parts availability.
- Can I use Rug Doctor cleaning solution in a Bissell carpet cleaner?
- Technically yes, but manufacturers recommend using their branded solutions for optimal results and warranty compliance. Bissell and Rug Doctor formulations are pH-balanced for their specific machines. Using cross-brand solutions may affect cleaning performance or leave residue. Both brands offer specialized formulas for pet stains and odors.
- Which carpet cleaner is best for pet stains?
- The Bissell ProHeat 2X Revolution Pet Pro 1986 is specifically designed for pet households with its CleanShot pretreater and pet-focused tools. The Rug Doctor Pet Portable Spot Cleaner excels at targeted spot cleaning for accidents. For whole-house deep cleaning with pets, the Bissell offers better coverage.
- How often should I deep clean my carpets?
- For homes with pets or children, deep clean carpets every 3 to 6 months. Homes without pets or heavy foot traffic can extend to every 12 to 18 months. High-traffic areas may need quarterly cleaning regardless of household composition.
- Are rental carpet cleaners better than owning one?
- Rental machines like commercial Rug Doctor units offer powerful extraction but cost $30 to $50 per day plus solution. If you deep clean quarterly or have pets requiring frequent spot cleaning, owning a quality machine like the Bissell Big Green pays for itself within 2 to 3 years. Ownership also allows immediate response to spills and accidents.
