Error one (1) means Roomba i Series is on an obstacle or an uneven surface and the left wheel is stuck. If this is the case, 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 left wheel for obstructions.
Use a Virtual Wall® to keep Roomba® away from problem areas.
-
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.
