About the Bissell CrossWave 1785

The Bissell CrossWave 1785 wet-dry cleaner uses a filter in its air path to trap fine debris and protect the motor. Because the CrossWave runs wet, keeping this filter clean is key to steady suction and pickup.

Step-by-Step: Replacing the Bissell CrossWave 1785 HEPA Filter

1
Power off and unplug
Switch off and unplug the CrossWave 1785 and empty the dirty-water tank.
2
Access the filter
Open the tank/air-path assembly to reach the washable filter.
3
Remove the old filter
Take out the filter and clear trapped debris.
4

Seat the new filter; if reusing, confirm it's dry.
5
Reassemble and test
Refit the tank, run briefly to confirm strong pickup.

⚠ Common mistakes on the CrossWave 1785

The CrossWave mistake is never rinsing the filter between cleans, so it clogs and pickup fades. The second is sealing a damp filter back into the tank, which traps odour — air-dry it first.
