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.

1. An autonomous coverage robot comprising: a body defining a chamber;a drive system disposed on the body and configured to maneuver the robot over a work surface; anda cleaning assembly carried by the body, the cleaning assembly comprising: first and second cleaning rollers rotatably coupled to the body within the chamber such that a wall of the chamber is positioned above an interface between the cleaning rollers and extends above an adjacent one of the cleaning rollers to define a passage between the chamber wall and the adjacent cleaning roller, wherein a leading portion of the chamber wall, in a direction of forward travel of the body, comprises a curved surface having a substantially constant radius that follows the circumference of the first cleaning roller at a substantially constant clearance;a suction duct in communication with the passage and disposed adjacent at least one of the cleaning rollers, the suction duct configured to receive debris dynamically lifted from the work surface between the cleaning rollers, through the passage towards the suction duct; anda container in fluid communication with the suction duct and configured to collect the debris drawn into the suction duct. 2. The robot of claim 1, wherein the first and second cleaning rollers are driven in opposite directions of rotation. 3. The robot of claim 2, wherein the first and second cleaning rollers are driven so that debris is agitated upward between the two rollers. 4. The robot of claim 1, wherein the suction duct is disposed above an axis of rotation of each of the first and second cleaning rollers. 5. The robot of claim 4, wherein the suction duct creates an air suction stream that conveys debris from the chamber substantially enclosing a top portion of the first and second cleaning rollers. 6. The robot of claim 1, wherein the suction duct is disposed rearward the first and second cleaning rollers in a direction of travel of the body. 7. The robot of claim 1, wherein the cleaning assembly comprises an air suction motor disposed in the container and in communication with the suction duct to convey debris agitated by the cleaning rollers into the container. 8. The robot of claim 1, wherein the container is disposed rearward of the first and second cleaning rollers. 9. The robot of claim 1, wherein one of the cleaning rollers comprises a bristle brush. 10. The robot of claim 1, wherein one of the cleaning rollers comprises a flapper brush. 11. The robot of claim 1, further comprising an edge cleaning head assembly disposed on the body, the edge cleaning head assembly comprising: an edge cleaning head housing;an edge cleaning head rotatably coupled to the edge cleaning head housing and configured to rotate about a non-horizontal axis; andan edge cleaning head motor coupled to the edge cleaning head;wherein the edge cleaning head extends beyond a lateral extent of the body to engage a floor surface while the robot is maneuvered across the floor. 12. The robot of claim 11, wherein the edge cleaning head defines an axis of rotation and is configured to tilt the axis of rotation with respect to a vertical position. 13. The robot of claim 12, wherein the axis of rotation of the edge cleaning head is configured to tilt to about 45° with respect to the vertical position. 14. The robot of claim 11, wherein the edge cleaning head assembly is positioned such that the edge cleaning head a site of contact between the work surface and the forward most cleaning roller of the first and second cleaning rollers, so as to move debris into a cleaning path of the cleaning rollers. 15. The robot of claim 1, wherein a rear wall of the container is positioned behind the first and second cleaning rollers in a direction of travel of the body. 16. The robot of claim 1, wherein at least a portion of the chamber wall is positioned directly above the interface between the cleaning rollers.
