An autonomous coverage robot includes a chassis, a drive system to maneuver the robot, an edge cleaning head carried, and a controller. The controller is configured to monitor motor current associated with the edge cleaning head and to reverse bias the edge cleaning head motor in response to an elevated motor current, while continuing to maneuver the robot across the floor. In another aspect, an autonomous coverage robot includes a drive system, a bump sensor, and a proximity sensor. The drive system is configured to reduce a speed setting in response to a signal from the proximity sensor indicating detection of a potential obstacle in a forward direction, while continuing to advance the robot according to a heading setting. Furthermore, the drive system is configured to alter the heading setting in response to a signal received from the bump sensor indicating contact with an obstacle.
