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 86T3 vs ProHeat 2X Pet Pro Plus 3588F, Compared: Before filling, Big Green weighs 24.5 lb more, though it holds 75% more solution
Quick verdict
Big Green suits cleaning several rooms on the same floor with fewer refills. ProHeat Pet Pro Plus 3588F suits you if the cleaner gets carried upstairs or you want a lighter maintenance-cleaning mode. Big Green holds 75% more clean solution, yet its empty body is 24.5 lb heavier.
Before you buy
Why, and what it costs you
A single Big Green fill equals 1.75 ProHeat fills
Repeated refills interrupt a multi-room job, and that is where the extra three quarters of a gallon matters.
Where this comes from
1.75 ÷ 1 = 1.75, or 75% more clean capacity. Coverage varies with how much you spray, the mode, repeated passes and stops to empty the recovery tank.
The catch
BISSELL ProHeat 2X Revolution Pet Pro Plus
You have to measure the solution into the clean tank yourself.

I haul the cleaner upstairs

I want a quick upkeep wash
Express Clean on the 3588F is described in the manual as a lighter clean. Save the deeper modes for jobs that call for them.

In practice
Differences you will notice
A single Big Green fill equals 1.75 ProHeat fills
Repeated refills interrupt a multi-room job, and that is where the extra three quarters of a gallon matters.
How we worked this out
1.75 ÷ 1 = 1.75, or 75% more clean capacity. Coverage varies with how much you spray, the mode, repeated passes and stops to empty the recovery tank.
A lighter body shifts the decision about going upstairs
Without water, ProHeat weighs about 58% less.
How we worked this out
42 - 17.5 = 24.5 lb. 24.5 divided by 42 is 58.3%. Compare empty weight to empty weight and leave shipping weight out.
Big Green gains reach at the hose and not at the outlet
You get one more foot of hose, with the same 25-foot cord.
How we worked this out
9 - 8 = 1 ft, which makes the hose 12.5% longer than ProHeat's. The cords are the same length.

Spec by spec
Where they really differ
| Spec | BISSELL Big Green Professional Carpet Cleaner | BISSELL ProHeat 2X Revolution Pet Pro Plus | In practice |
|---|---|---|---|
| Clean solution capacity | 1.75 gallons | 1 gallon | Big Green carries 75% more solution, but that does not guarantee 75% more carpet gets covered. |
| Empty carrying weight | 42 lb | 17.5 lb | ProHeat takes 24.5 lb off the empty lift, before any water or accessories are added. |
| Power cord | 25 ft | 25 ft | Between these two, the bigger machine does not get you farther from the outlet. |
| Attachment hose | 9 ft | 8 ft | A safely parked machine gets one extra foot with Big Green. |
| Floor cleaning path | 10.5 inches | 11 inches | ProHeat's head is a half-inch wider, which does not show that whole rooms get cleaned faster. |
| Heat and pretreatment | No heater, warm tap water | Heatwave temperature maintenance and CleanShot | ProHeat is not steam. CleanShot applies pretreatment solution. |
| Lighter cleaning mode | No comparable Express mode listed | Express Clean, about 30-minute drying claim | Per the manual, Express is a lighter clean and not a quicker take on MAX cleaning. |
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 BISSELL ProHeat 2X Revolution Pet Pro Plus
- After each use, you still have to pull hair and formula residue out of the nozzle and brush area.
Change of plan
When the answer changes
The machine never leaves a single floor, and long sessions get interrupted by refilling.
Go with BISSELL Big Green Professional Carpet Cleaner. The larger clean tank deals with those interruptions, and you do not have to carry its 42 lb body upstairs.
You put cleaning off mainly because of the weight to carry.
Go with BISSELL ProHeat 2X Revolution Pet Pro Plus. A 17.5 lb empty body makes far more practical difference than the half-inch gap in path width.
Decision guide
How to decide
Big Green is the choice when several rooms on the same floor need cleaning and fewer refills matter. ProHeat Pet Pro Plus 3588F is the choice when the cleaner is carried upstairs or a lighter maintenance-cleaning mode appeals. The 75% extra clean solution in Big Green comes with an empty body that weighs 24.5 lb more.
Settle where the machine will be kept
A larger tank pays off during the cleaning, and a heavier body shows up before and after it. Big Green's weight may be acceptable if the cleaner is kept upstairs next to the rooms it washes. When every session begins with a staircase, ProHeat's lighter body is a more useful advantage than a slight difference in cleaning-path width.
Tank size is not a room count
Gallons can't honestly be converted into bedrooms unless you know how much solution you apply and how often you repeat a pass. Big Green gives you a bigger liquid reserve, but that does not prove a stain disappears sooner or that the recovery tank never interrupts the job.
Keep the drying claim tied to its mode
The approximate 30-minute figure for ProHeat applies to Express Clean, a lighter wash with its own pace and passes. It does not promise that deeply soaked carpet dries in half an hour. Choose that feature if maintenance washes are in your plans, and let the carpet dry completely before walking on it.
What this page can’t tell you
- Dimensions and capacities from the manufacturer can't pick a winner on stain removal.
- Express drying time is a claim the manufacturer makes for that mode only, and it is no guarantee for your carpet or your humidity.
