Abstract
An autonomous cleaning robot includes a drive configured to move the robot across a floor surface, a brush proximate a lateral side of the robot, and a motor configured to rotate the brush about an axis of rotation. The brush includes a hub configured to engage the motor of the robot and arms each extending outwardly from the hub away from the axis of rotation and each being angled relative to a plane normal to the axis of rotation of the brush. Each of the arms include a first portion extending outwardly from the hub away from the axis of rotation and a second portion extending outwardly from the first portion away from the axis of rotation. An angle between the first portion of each of the arms and the plane is larger than an angle between the second portion of the each of the arms and the plane.
