An autonomous floor cleaning robot includes a transport drive and control system arranged for autonomous movement of the robot over a floor for performing cleaning operations. The robot chassis carries a first cleaning zone comprising cleaning elements arranged to suction loose particulates up from the cleaning surface and a second cleaning zone comprising cleaning elements arraigned to apply a cleaning fluid onto the surface and to thereafter collect the cleaning fluid up from the surface after it has been used to clean the surface. The robot chassis carries a supply of cleaning fluid and a waste container for storing waste materials collected up from the cleaning surface.

1. A surface treatment robot comprising: a robot body having a forward portion and a rear portion;a differential drive system mounted on the robot body and configured to maneuver the robot over a cleaning surface;a controller in communication with the drive system and configured to differentially steer the robot;a proximity sensor responsive to an obstacle forward of the robot, wherein the controller is configured to alter a heading setting in response to a signal received from the proximity sensor indicating a potential obstacle;a cliff sensor responsive to a potential cliff, wherein the controller is configured to alter the heading setting in response to a signal received from the cliff sensor indicating a potential cliff; anda passive scrubbing element disposed across a cleaning width of about 10 cm to 40 cm such that a shear force is generated between the passive scrubbing element and the cleaning surface as the robot moves over the cleaning surface, wherein an average drag force between the surface treatment robot and the cleaning surface is up to about 40% of the weight of the surface treatment robot and the surface treatment robot has a mass of less than about 10 kg. 2. The surface treatment robot of claim 1, further comprising a liquid applicator supported on the robot body to distribute cleaning fluid onto the cleaning surface across the cleaning width. 3. The surface treatment robot of claim 2, wherein the liquid applicator is a spreader brush or a wiper arranged to apply cleaning fluid directly to the cleaning surface. 4. The surface treatment robot of claim 1, wherein the cleaning width is disposed along a portion of the robot body having a height less than a portion of the robot body away from the cleaning width. 5. The surface treatment robot of claim 4, wherein the height of the robot body is less than 4 inches and the robot body fits within a diameter of about 20-50 cm. 6. The surface treatment robot of claim 1, wherein the differential drive system comprises first and second drive wheels disposed rear of the passive scrubbing element as the robot moves in the forward direction. 7. The surface treatment robot of claim 6, wherein the first and second drive wheels are each disposed rear of a center point of the robot body as the robot moves in the forward direction. 8. The surface treatment robot of claim 6, wherein the first and second drive wheels are each positioned at an outer edge of the robot body. 9. The surface treatment robot of claim 6, wherein the first and second drive wheels each support no more than 3 to 4 kg. 10. The surface treatment robot of claim 1, wherein the differential drive system comprises first and second drive wheels each biased to move toward the cleaning surface when the respective wheel loses contact with the cleaning surface. 11. The surface treatment robot of claim 10, wherein the cliff sensor is configured to sense the loss of contact between the respective wheel and the cleaning surface. 12. The surface treatment robot of claim 1, wherein the proximity sensor responsive to the obstacle forward of the robot comprises a displaceable bumper disposed along the forward portion of the robot body. 13. The surface treatment robot of claim 12, wherein the ground clearance of the displaceable bumper is about 2 mm to 5 mm. 14. The surface treatment robot of claim 1, wherein the passive scrubbing element is releasably supported across the cleaning width. 15. The surface treatment robot of claim 1, wherein the passive scrubbing element is configured to agitate a cleaning fluid dispensed on the cleaning surface. 16. The surface treatment robot of claim 15, further comprising a reservoir defining a volume for storing the cleaning fluid. 17. The surface treatment robot of claim 16, wherein the reservoir is releasably attachable to the robot body. 18. The surface treatment robot of claim 16, wherein at least a portion of the reservoir is disposed above the passive scrubbing element as the robot move across the cleaning surface. 19. The surface treatment robot of claim 1, wherein the passive scrubbing element is a passive scrubbing element including one or more of the following: a scrub brush, wiper, and a wipe cloth.
