Main trade-off
BISSELL Big Green Professional Carpet Cleaner
The commercial-style body is heavy to carry and takes substantial closet space.
Head-to-head
BISSELL Big Green vs Rug Doctor Pro Deep: Big Green includes a hose tool, Rug Doctor’s powered upholstery tool is extra
The short answer
Choose BISSELL Big Green for a large clean-water tank and an included hose and stain tool. Choose Rug Doctor Pro Deep if you want its back-and-forth rental-style workflow and clear tank or brush warnings. Check the accessory bundle carefully because Rug Doctor's motorized upholstery tool is sold separately.

About this comparison

Before you choose
How they fit your plans
Big Green's professional size does not mean onboard heating
BISSELL explicitly says Big Green has no heater. If your purchase depends on a machine actively heating the solution, its large tanks and professional branding do not meet that requirement. The reviewed Pro Deep evidence also does not establish the required heating function, so verify it before choosing. If heated solution is not essential, compare the existing reach and tank differences using the manufacturers' filling instructions.
Facts behind this advice
This rules out an unsupported capability rather than ranking cleaning quality. Water temperature permitted at filling is different from a machine that maintains or generates heat while cleaning.
A supplied upholstery nozzle and an optional powered tool differ
Big Green's included six-inch stain tool makes the selected package ready for permitted upholstery extraction without another basic accessory purchase. Pro Deep's motorized upholstery tool is optional. Choose Big Green if the included nozzle covers the job. Choose Pro Deep only after confirming and budgeting for the powered attachment if that specific mechanism is why you prefer it. Neither package proves better fur removal from fabric.
Facts behind this advice
This goes beyond tool presence by separating supplied nozzle extraction from an optional motorized mechanism. The floor brush on the main machine does not become a powered sofa brush when a hose is attached.

What matters in practice
The differences that matter
The clean-tank increase is 16.7%
Big Green carries a quarter gallon more solution.
How we reached this conclusion
(1.75 − 1.5) ÷ 1.5 × 100 = 16.67%. Cleaning coverage depends on application rate.
One fewer fill only appears at some job sizes
A 3.5-gallon solution job needs two Big Green fills or three Pro Deep fills.
How we reached this conclusion
Ceiling(3.5 ÷ 1.75)=2. Ceiling(3.5 ÷ 1.5)=3. Excludes separate recovery-tank stops.
The included tool changes the purchase
Big Green already covers hand-tool cleaning in its listed kit.
How we reached this conclusion
Manufacturer lists a nine-foot hose and six-inch stain tool. Pro Deep lists the motorized tool separately.

Meaningful differences
What changes the fit
| What changes | BISSELL Big Green Professional Carpet Cleaner | Rug Doctor Pro Deep with Oxy Bundle | Why it matters |
|---|---|---|---|
| Clean-water capacity | 1.75 gallons | 1.5 gallons | Big Green holds an extra quarter gallon per fill. |
| Upholstery setup | 9-foot hose and 6-inch tool included | Motorized upholstery tool sold separately | Compare the full kit if furniture cleaning matters. |
| Cleaning direction | Forward and backward passes | Back-and-forth cleaning motion | Neither forces a pull-only whole-room workflow. |
| Status guidance | Conventional operating checks | Solution-empty and brush-jam lights | Rug Doctor makes two interruptions more obvious. |
| Clean-water weight added | About 14.6 pounds at full fill | About 12.5 pounds at full fill | Tank size affects handling as well as capacity. |
What you give up
Every choice has a cost
If you choose BISSELL Big Green Professional Carpet Cleaner
- Its wide commercial-style head is slower to turn in a small furnished room.
If you choose Rug Doctor Pro Deep with Oxy Bundle
- A 1.5-gallon fill makes the machine substantially heavier during use.
What matters in practice
How to make the call
A bigger tank reduces only some interruptions
Big Green holds 1.75 gallons of clean solution against 1.5 gallons for Pro Deep. For a job using exactly three gallons, both need two fills. For exactly 3.5 gallons, Big Green still needs two while Pro Deep needs three. Dirty-tank emptying, overlap and your spraying habits can create extra stops, so capacity cannot be converted straight into rooms cleaned.
Price the complete floor-and-sofa kit
Big Green includes a nine-foot hose and six-inch stain tool. Rug Doctor lists its motorized upholstery tool as a separate purchase. If sofas and stairs are part of your regular routine, compare the combined basket cost instead of the washer alone. If you only need open-floor cleaning, an unused tool kit should not decide the purchase.
The water makes a heavy appliance heavier
Big Green weighs 42 pounds empty. Filling its 1.75-gallon clean tank adds about 14.6 pounds of water, giving roughly 56.6 pounds before recovered water or extra accessories. Pro Deep's 1.5-gallon fill adds around 12.5 pounds to its empty body. These are floor-cleaning machines to position thoughtfully, not portable stain cleaners to carry from spill to spill.
What this comparison cannot tell you
- Fill examples assume a specified solution volume, not a measured room size.
- No matched extraction or dry-time test establishes a performance winner.
