The catch
BISSELL Big Green Professional Carpet Cleaner
It's a heavy, commercial-style machine to haul around, and it claims a lot of closet space.
Side by side
BISSELL Big Green vs Rug Doctor Pro Deep Compared: Rug Doctor’s powered upholstery tool is extra, whereas Big Green includes a hose tool
Quick verdict
Go with BISSELL Big Green for its large clean-water tank and the hose and stain tool that come with it. Go with Rug Doctor Pro Deep for its back-and-forth, rental-style workflow and its clear warnings about the tank or brush. Look closely at the accessory bundle, because Rug Doctor's motorized upholstery tool is sold separately.
Before you buy
Why, and what it costs you
The clean tank is 16.7% bigger
Big Green takes an extra quarter gallon of solution.
Where this comes from
(1.75 − 1.5) ÷ 1.5 × 100 = 16.67%. How much area that covers depends on how heavily you apply it.

What this page compares
Big Green 86T3 and Rug Doctor Pro Deep, compared on tank refills, the upholstery tools in the box and how heavy the machine gets during a full cleaning session.
Day to day
How each one fits your routine
A professional size on Big Green does not come with onboard heating
BISSELL states outright that Big Green has no heater. When you are buying a machine specifically to heat the solution as it cleans, big tanks and professional branding do not satisfy that need. The Pro Deep evidence that was reviewed does not confirm a heating function either, so check before you choose. When heated solution is not essential, weigh the reach and tank differences that are there, following the manufacturers' filling directions.
Where this comes from
The aim here is to exclude a capability nobody has shown. It does not rank cleaning quality. Water temperature allowed at filling is not the same as a machine that keeps or makes heat during cleaning.
An upholstery nozzle in the box and an optional powered tool are not the same thing
The six-inch stain tool that comes with Big Green means the package you chose can extract from upholstery that allows it, with no basic accessory to buy afterward. Pro Deep's motorized upholstery tool is optional. Go with Big Green if the nozzle in the box handles the job. Go with Pro Deep only if that powered mechanism is the reason you prefer it, and only after you confirm the attachment and budget for it. Neither package has been shown to remove fur from fabric better.
Where this comes from
This looks past whether a tool is present and separates extraction through a supplied nozzle from an optional motorized mechanism. Attaching a hose does not turn the main machine's floor brush into a powered sofa brush.

In practice
Differences you will notice
The clean tank is 16.7% bigger
Big Green takes an extra quarter gallon of solution.
How we worked this out
(1.75 − 1.5) ÷ 1.5 × 100 = 16.67%. How much area that covers depends on how heavily you apply it.
Needing one less fill depends on the size of the job
Big Green handles a 3.5-gallon solution job in two fills, while Pro Deep needs three.
How we worked this out
Ceiling(3.5 ÷ 1.75)=2. Ceiling(3.5 ÷ 1.5)=3. Stops to empty the recovery tank are not counted.
The tool in the box affects what you are buying
The kit listed for Big Green already handles hand-tool cleaning.
How we worked this out
The manufacturer lists a nine-foot hose and a six-inch stain tool. For Pro Deep, the motorized tool is listed as a separate item.

Spec by spec
Where they really differ
| Spec | BISSELL Big Green Professional Carpet Cleaner | Rug Doctor Pro Deep with Oxy Bundle | In practice |
|---|---|---|---|
| Clean-water capacity | 1.75 gallons | 1.5 gallons | Each Big Green fill gets you an additional quarter gallon. |
| Upholstery setup | 9-foot hose and 6-inch tool included | Motorized upholstery tool sold separately | If you will clean furniture, compare what the whole kit includes. |
| Cleaning direction | Forward and backward passes | Back-and-forth cleaning motion | Neither locks you into pull-only room cleaning. |
| Status guidance | Conventional operating checks | Solution-empty and brush-jam lights | With Rug Doctor, two kinds of interruption are easier to spot. |
| Clean-water weight added | About 14.6 pounds at full fill | About 12.5 pounds at full fill | Besides capacity, tank size changes how the machine handles. |
Trade-offs
What each pick costs you
With BISSELL Big Green Professional Carpet Cleaner
- The wide commercial-style head is slow to turn around in a small furnished room.
With Rug Doctor Pro Deep with Oxy Bundle
- While in use, the machine gets much heavier once a 1.5-gallon fill goes in.
Decision guide
How to decide
A large clean-water tank plus an included hose and stain tool point to BISSELL Big Green. A back-and-forth, rental-style workflow with clear tank and brush warnings points to Rug Doctor Pro Deep. Verify the accessory bundle, since Rug Doctor's motorized upholstery tool is sold separately.
Some interruptions go away with a bigger tank, not all
Big Green's clean tank holds 1.75 gallons, compared with 1.5 gallons on Pro Deep. A job that uses exactly three gallons takes two fills on both. At exactly 3.5 gallons, Big Green still takes two fills and Pro Deep takes three. Emptying the dirty tank, overlap and how you spray can add extra stops, so you can't turn capacity directly into rooms cleaned.
Add up the cost of the full floor-and-sofa kit
A nine-foot hose and a six-inch stain tool come with Big Green. On Rug Doctor, the motorized upholstery tool is listed as a separate purchase. When sofas and stairs are part of your routine, compare the cost of the full basket, tools included. When all you need is open-floor cleaning, a tool kit you won't use shouldn't drive the decision.
Water adds to an already heavy appliance
Empty, Big Green weighs 42 pounds. Fill its 1.75-gallon clean tank and about 14.6 pounds of water go on top, which brings it to roughly 56.6 pounds before any recovered water or extra accessories. A 1.5-gallon fill adds around 12.5 pounds to the empty body of Pro Deep. Treat these as floor-cleaning machines you place with care. They are not portable stain cleaners to carry from spill to spill.
What this page can’t tell you
- The fill examples start from a set solution volume. They do not use a measured room size.
- Without a matched extraction or dry-time test, no performance winner can be named.
