1. An autonomous cleaning robot, comprising:

  • at least one motorized drive wheel mounted to the robot and arranged to propel the robot across a surface;

    a pair of cleaning rollers mounted to the robot and having outer surfaces exposed on an underside of the robot and to each other, the cleaning rollers drivable to counter-rotate while the robot is propelled, thereby cooperating to direct raised debris upward into the robot between the rollers; and

    a side brush mounted to the robot to rotate beneath the robot adjacent a lateral side of the robot about an upwardly extending side brush axis;

    wherein an outer surface of a first of the cleaning rollers of the pair extends laterally beyond an outer surface of a second of the cleaning rollers and laterally beyond the side brush axis, such that the first cleaning roller defines a cleaning width spanning the side brush axis.
