An autonomous coverage robot detection system includes an emitter configured to emit a directed beam, a detector configured to detect the directed beam and a controller configured to direct the robot in response to a signal detected by the detector. In some examples, the detection system detects a stasis condition of the robot. In some examples, the detection system detects a wall and can follow the wall in response to the detected signal.

1. An autonomous robot comprising: a body;right and left driven wheels coupled to the body, the robot maneuverable over a cleaning surface by the right and left driven wheels;a vacuum assembly configured to suction waste from the cleaning surface;a collection volume disposed within the body, the collection volume in fluid communication with the vacuum assembly for collecting waste suctioned by the vacuum assembly, and the body defining a first opening through which the collected waste is removable from the collection volume;a seal movable to interrupt at least a portion of the fluid communication between the vacuum assembly and the collection volume; anda biased-to-drop suspension system coupled to the driven wheels, the biased-to-drop suspension system having a top position and a bottom position, and the seal being coupled to the suspension system and movable to interrupt at least a portion of the fluid communication between the vacuum assembly and the collection volume as the biased-to-drop suspension system moves from the top position to the bottom position. 2. The autonomous robot of claim 1, wherein the seal is movable in response to removal of the driven wheels from the cleaning surface. 3. The autonomous robot of claim 2, wherein the seal is movable in response to an electrical signal indicative of the position of the driven wheels. 4. The autonomous robot of claim 2, wherein the seal is holdable in an open position, permitting fluid communication between the vacuum assembly and the collection volume, in response to the driven wheels supporting the robot on the cleaning surface. 5. The autonomous robot of claim 1, wherein the vacuum assembly comprises a fan and the seal is movable to interrupt at least a portion of the fluid communication between the fan and the collection volume. 6. The autonomous robot of claim 1, further comprising a liquid supply volume and a liquid delivery system configured to move fluid from the liquid supply volume to the cleaning surface, wherein the body defines a second opening through which cleaning liquid is deliverable to the liquid supply volume. 7. The autonomous robot of claim 6, wherein the first opening is defined substantially opposite the second opening such that waste is removable from the collection volume while liquid is deliverable to the liquid supply volume. 8. The autonomous robot of claim 6, wherein the body defines a first door and a second door, the first door movable to expose the first opening through which waste is removable from the collection volume, and the second door movable to expose the second opening through which cleaning liquid is deliverable to the liquid supply volume. 9. The autonomous robot of claim 6, wherein all or a portion of the liquid supply volume is a flexible bladder surrounded by the collection volume. 10. The autonomous robot of claim 6, wherein an overall height of the robot is less than about 18 centimeters, a width of the robot is less than about 26 centimeters, and the robot weighs less than 3 kg with the liquid supply volume full of cleaning fluid. 11. The autonomous robot of claim 10, wherein the liquid supply volume is at least about 20 percent of the volume of the robot. 12. An autonomous robot comprising: a body;right and left driven wheels coupled to the body, the robot maneuverable over a cleaning surface by the right and left driven wheels;a collection volume disposed within the body, the collection volume in fluid communication with the cleaning surface collecting waste removed from the cleaning surface as the robot maneuvers over the cleaning surface, and the body defining an opening through which the collected waste is removable from the collection volume;a seal movable, in response to removal of the driven wheels from the cleaning surface, to interrupt at least a portion of the fluid communication between the collection volume and the cleaning surface; anda biased-to-drop suspension system coupled to the driven wheels, the biased-to-drop suspension system having a top position and a bottom position, and the seal being coupled to the suspension system movable to interrupt at least a portion of the fluid communication between the collection volume and the cleaning surface as the biased-to-drop suspension system moves from the top position to the bottom position. 13. The autonomous robot of claim 12, wherein the seal is movable in response to an electrical signal indicative of the position of the driven wheels. 14. The autonomous robot of claim 12, wherein the seal is movable in response to removal of the driven wheels from the cleaning surface. 15. The autonomous robot of claim 12, wherein the seal is holdable in an open position, permitting fluid communication between a vacuum assembly and the collection volume, in response to the driven wheels supporting the robot on the cleaning surface. 16. The autonomous robot of claim 15, wherein the vacuum assembly comprises a fan and the seal is movable to interrupt at least a portion of the fluid communication between the fan and the collection volume. 17. The autonomous robot of claim 12, further comprising a liquid supply volume and a liquid delivery system configured to move fluid from the liquid volume to the cleaning surface, wherein the body defines a second opening through which cleaning liquid is deliverable to the liquid supply volume. 18. The autonomous robot of claim 17, wherein an overall height of the robot is less than about 18 centimeters, a width of the robot is less than about 26 centimeters, and the robot weighs less than 3 kg with the liquid supply volume full of cleaning fluid. 19. The autonomous robot of claim 17, wherein the liquid supply volume is at least about 20 percent of the volume of the robot.
