    iRobot's steps: press the bin release button to remove the bin, open the bin door and empty it, take the filter out from the left side of the bin and tap the debris off it (filters are not designed to be washed or to touch liquid), put the filter back and slide the bin in. If it persists, remove the filter and rinse the bin with warm water, letting it dry completely; the bin is rinsed by hand only and is not dishwasher safe. The j Series and s Series charts word this error the same way.

Model-specific

What is true of this model and not of its siblings

Filters are not washable
iRobot's filters are not designed to be washed or to touch liquid; tapping off the debris is the method. A wet filter can damage the motor.
A blocked path
If the filter is clean, look for debris in the airway behind the bin, using a flashlight.
Regular care
Empty the bin after each run and replace the filter on iRobot's schedule.
Filter life
iRobot recommends replacing the filter on a regular schedule, commonly every couple of months with normal use. A filter that keeps clogging or looks permanently gray has done its job and needs replacing.
A gentle test
Run the robot with the bin removed and listen: a healthy motor spins up evenly. A grinding or silent motor points to a part that needs service rather than cleaning.
Keeping suction up
Run the robot only with the filter and the bin correctly seated, empty the bin each run on a pet household and replace the brush rolls when they are worn. Weak suction from a clean filter often means a worn brush roll or a blocked airway.
