Abstract
A floor-cleaning robot includes a wheeled housing having a perimeter, a motor drive operably connected to wheels of the housing to move the robot across a floor surface, and a bumper responsive to obstacles encountered by the robot. A controller is in electrical communication with both the bumper and the motor drive and is configured to control the motor drive to maneuver the robot to avoid detected obstacles across the floor surface during a floor-cleaning operation. A driven cleaning brush, rotatable about an axis substantially parallel to an underside of the housing, is disposed substantially across a central region of the underside and is positioned to brush the floor surface as the robot is moved across the floor surface. Additionally, a driven side brush extending beyond the perimeter is positioned to brush floor surface debris from beyond the perimeter toward a projected path of the driven cleaning brush.
