PROBLEM TO BE SOLVED: To provide an improved cleaning head for a robotic vacuum.SOLUTION: An autonomous coverage robot has a chassis having a forward portion and a rearward portion. A drive system is mounted to the chassis and configured to maneuver the robot over a cleaning surface.. A cleaning assembly is mounted on the forward portion of the chassis and has two or more counter-rotating rollers mounted therein for retrieving debris from the cleaning surface, the longitudinal axis of the forward roller lying in a first horizontal plane positioned above a second horizontal plane on which the longitudinal axis of the rearward roller lies.. The cleaning assembly is movably mounted to the chassis by a linkage affixed at a forward end to the chassis and at a rearward end to the cleaning assembly. When the robot transitions from a firm surface to a compressible surface, the linkage lifts the cleaning assembly from the cleaning surface.SELECTED DRAWING: Figure 1 |
