Roomba i4 i4+ Clean Base won't empty the robot
Symptom: On the i4+, the robot docks but the Clean Base never runs its loud evacuation, so the robot bin stays full; the app may report the bin is full or the base couldn't empty. Likely root causes: Robot not seated squarely on the Clean Base contacts; Clean Base dirt-disposal bag full or not seated (see FM-23); Evacuation port in the BOTTOM of the robot bin blocked by hair/debris; Clean Base evacuation tube / dock funnel clogged (see FM-24); Clean Base unplugged or on a switched/dead outlet; Bag not detecting (lid not fully closed, or a non-genuine bag without the sensor tab) Next steps if owner-level checks fail: Base still won't run the evacuation motor with power, a good bag, a clear port and a square dock — the Clean Base motor or sensor may be faulty; contact iRobot Customer Care 1-877-855-8593
