Abstract: An autonomous cleaning robot comprises a chassis, at least one motorized drive wheel mounted to the chassis and arranged to propel the robot across a surface, and a pair of cleaning rollers mounted to the chassis and having outer surfaces exposed on an underside of the chassis and to each other. The cleaning rollers are drivable to counter-rotate while the robot is propelled, thereby cooperating to direct raised debris upward into the robot between the rollers. A side brush is further mounted to the chassis to rotate beneath the chassis adjacent a lateral side of the chassis about an upwardly extending side brush axis, and the outer surface of a first of the cleaning rollers of the pair extends laterally beyond the outer surface of a second of the cleaning rollers of the pair and laterally beyond the side brush axis, such that the first cleaning roller defines a cleaning width spanning the side brush axis.
