Coverage robot mobility
First Claim
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; and
a 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; and
a container in fluid communication with the suction duct and configured to collect the debris drawn into the suction duct.

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.
