Manufacturer checks in order
- Lift Roomba off the floor, place it in the center of the room and restart the clean cycle.
- If this error occurred on a flat surface, check the wheels for obstructions.
- Push the wheels up and down several times and shake out any loose debris that may be trapped in the wheel well.
- Briskly turn both wheels by hand and make sure they turn freely and that each wheel exhibits the same amount of resistance.
- Inspect the front caster wheel on the robot to ensure it is free of any debris.
