When the brush roll on a BigGreen ProCup upright stops turning, or the belt indicator lights up, this is the part. It is the toothed drive belt for the Bissell BigGreen Commercial ProCup uprights, listed as 2037771 and carried by Bissell under the current number 40332-01, and it fits the BGUPRO14T and the BGUPRO18T.
This is a cogged belt, not a stretch flat belt, and the difference shows up in the middle of a shift. A flat belt slips a little more as it heats, brush RPM drops, and agitation quietly fades even though the machine sounds fine. Molded teeth mesh instead of gripping by friction, so brush speed stays where the design intends it. On a dual-motor machine that is the whole point, since the separate brush motor is what delivers the one-pass result the ProCup line is sold on.
In-house janitorial teams and building service contractors are the usual buyers, and the ones who run these fleets well buy belts in multiples. Repair guidance across the trade agrees on the leading avoidable cause of belt failure: debris jamming the brush roll. A cord, a length of string, or a plastic strap wraps the brush, the belt heats and stretches against the obstruction, and it snaps, often with a burnt rubber smell as the warning. Clearing the brush roll and checking bearings when you change the belt is what keeps the next one from failing the same way.
Service guidance on machines in this class suggests planning belts on roughly a six-month cycle and brush rolls annually under normal commercial use, adjusted for how abrasive your floors are. Keeping a belt in the stockroom turns an out-of-service machine into a five-minute repair.

Frequently asked questions
Is 2037771 the same as 40332-01?
Yes. 40332-01 is the current Bissell number for this belt and 2037771 is the legacy number that many dealers and parts lists still show. They are the same part for the BGUPRO14T and BGUPRO18T.
Does one belt fit both the 14 inch and the 18 inch machine?
Yes. Bissell lists this belt for both the BGUPRO14T and the BGUPRO18T.
How often should we replace it?
Service guidance for machines in this class points to roughly every six months under normal commercial use, with brush rolls annually. Abrasive soil and long daily run times shorten that, so inspect the belt whenever the base plate is off.
My belt keeps breaking. What am I missing?
Almost always a jammed brush roll. Pull the base plate, cut away wrapped string, hair and strapping, and spin the brush by hand to confirm the bearings turn freely. A brush that binds will destroy every belt you put on it.
Will the belt-break sensor reset after I replace it?
The sensor reports the condition it detects, so once the belt is properly seated and the brush turns freely, the fault indication should clear on restart. If it does not, the brush roll or its bearings are still binding.
