Bissell Dirty Water Tank Float for TurboClean Upright 3746 3738 3748 3745

The float inside a Bissell TurboClean's dirty water tank is a small but important safety part: as the tank fills, it rises with the water level until it seats against the suction port and cuts off airflow, so the motor never draws in water while the tank is full. This cobalt blue float is part 164-1207.

A float that has cracked, absorbed water, or lost buoyancy will not rise properly, and the result is either an overfilled tank or suction that cuts out early even when the tank still has room left. A float that has come loose from its cage can also rattle audibly inside the tank.

• Part: 164-1207 dirty tank float
• Fits: Bissell TurboClean upright, models 3738, 3745, 3746, 3748 and 3748N
• Color: Cobalt Blue
• Function: shuts off suction when the dirty tank reaches full

Match the number on your TurboClean unit to the models listed above to make sure part 164-1207 is the right float.

A quick way to test a suspect float without removing the tank is to run the machine with the dirty tank completely empty; if suction cuts out or behaves inconsistently with nothing inside, the float itself is usually the problem rather than the tank seal. A float that rattles when you shake the empty tank has likely come loose from its cage.
