When the lid on your Big Green Machine's dirty water tank cracks, warps, or stops sealing, you notice it fast: water seeps from the recovery tank, suction drops off, and the carpet stays wetter than it should after a pass. This genuine Bissell Dirty Tank Lid Assembly is the fix for owners of the Big Green carpet cleaner who want to restore a tight seal and proper water separation rather than retire an otherwise good machine. It is the same lid Bissell ships from the factory, complete with the built-in carry handle, so your cleaner goes back to pulling dirty water cleanly into the recovery tank and lifting moisture out of the carpet the way it did when new. For households, rental fleets, and cleaning crews alike, a fresh lid is the difference between a leaky, weak-suction machine and one that finishes the job dry.
Use cases
- Replace a cracked, warped, or leaking dirty-tank lid that is letting recovery water escape during use.
- Restore lost suction and proper air-water separation when the old lid no longer seals against the tank.
- Swap in a fresh handle assembly when the original lid handle has broken or pulled loose.
- Keep a commercial or rental Big Green Machine in service with a genuine OEM replacement instead of a guess-fit aftermarket part.
- Stock a spare lid for high-use professional and pet-cleaning machines that see heavy daily duty.

Frequently asked questions
Which Bissell models does this lid fit?
It fits the Big Green Carpet Cleaner Machine line, including the BG10, BG10N2, and 86T3, as well as the Big Green Professional, Commercial, and PET PRO machines that use part 2037449 or 1605234.
Is this the lid for the dirty tank or the clean-water tank?
This is the dirty (recovery) water tank lid, the one with the carry handle that seals the tank holding the soiled water pulled up from the carpet.
Will replacing the lid stop my machine from leaking?
If the leak comes from a cracked, warped, or poorly sealing dirty-tank lid, a fresh assembly with an intact seal commonly resolves it. Leaks from the tank body, hoses, or clean-water side are separate parts.
Do I need tools to install it?
No. Remove the old lid from the dirty water tank and seat the new assembly in its place, then confirm it sits flat and sealed before running the machine.
Is this a genuine Bissell part?
Yes. This is the authentic Bissell dirty tank lid assembly, not a generic substitute, so it matches the original fit and seal.
