Autonomous coverage robot
First Claim
1. A mobile surface cleaning robot comprising:
- a robot body having a forward drive direction;
a drive system supporting the robot body above a floor surface for maneuvering the robot across the floor surface;
a robot controller in communication with the drive system;
a collection volume supported by the robot body;
a cleaning cartridge releasably supported by the robot body and arranged to clean the floor surface, the cleaning cartridge comprising;
a first vacuum squeegee having a first duct;
a driven roller brush rotatably supported rearward of the first vacuum squeegee;
a second vacuum squeegee disposed rearward of the roller brush and having a second duct; and
a third duct in fluid communication with the first and second ducts, the third duct connectable to the collection volume at a fluid-tight interface formed by selectively engaging the cartridge with the robot body;
a liquid applicator supported by the robot body rearward of the second vacuum squeegee;
a fluid accumulator supported by the robot body and in fluid communication with the liquid applicator; and
a smearing element suspended from the robot body by the fluid accumulator, the smearing element delivering fluid from the fluid accumulator onto the floor surface, wherein the fluid accumulator extends along the length of the smearing element.

Abstract
A mobile surface cleaning robot including a robot body having a forward drive direction, a drive system supporting the robot body above a floor surface for maneuvering the robot across the floor surface, and a robot controller in communication with the drive system. The robot also includes a collection volume supported by the robot body and a cleaning module releasably supported by the robot body and arranged to clean the floor surface. The cleaning module includes a first vacuum squeegee having a first duct, a driven roller brush rotatably supported rearward of the first vacuum squeegee, a second vacuum squeegee disposed rearward of the roller brush and having a second duct, and a third duct in fluid communication with the first and second ducts. The third duct is connectable to the collection volume at a fluid-tight interface formed by selectively engaging the cartridge with the robot body.

19. A mobile surface cleaning robot comprising:
-
a robot body having a forward drive direction; a drive system supporting the robot body above a floor surface for maneuvering the robot across the floor surface; a wet cleaning system supported by the robot body and arranged to clean the floor surface; and a robot controller in communication with at least one of the drive system or the cleaning system; wherein the cleaning system comprises; a liquid collection volume defining at least one fluid orifice and a shaft aperture; and an anti-spill device in communication with the robot controller, the robot controller causing the anti-spill device to open and close the at least one orifice based on a robot state, the anti-spill device comprising; at least one orifice sealer supported inside the liquid collection volume to move between an open position that allows fluid through the least one fluid orifice and a closed position that seals the at least one fluid orifice closed; an actuator shaft coupled to the at least one orifice sealer and supported to move through the shaft aperture defined by the liquid collection volume; and an orifice opener actuator coupled to the actuator shaft and in communication with the robot controller, the orifice opener actuator configured to move the actuator shaft to cause movement of the at least one orifice sealer between the open and closed positions.
