Abstract

An autonomous coverage robot includes a body having at least one outer wall, a drive system disposed on the body and configured to maneuver the robot over a work surface, and a cleaning assembly carried by the body. The cleaning assembly includes first and second cleaning rollers rotatably coupled to the body, a suction assembly having a channel disposed adjacent at least one of the cleaning rollers, and a container in fluid communication with the channel. The container is configured to collect debris drawn into the channel. The suction assembly is configured to draw debris removed from the work surface by at least one of the cleaning rollers into the channel, and the container has a wall common with the at least one outer wall of the body.
