Abstract
An autonomous mobile cleaning robot can include a cleaning assembly and a drive wheel. The cleaning assembly can be configured to lift debris from a surface and direct the debris into a dustpan. The drive wheel can be configured to move the autonomous mobile cleaning robot on the surface. The drive wheel can include a first set of treads configured to climb an obstacle, a second set of treads configured to maintain continuous contact with a surface of a floor, and third set of treads configured to direct water underneath the third set of treads towards a center of the autonomous mobile cleaning robot.
