International Classification:

A47L 7/00
B08B 3/04
G01C 21/00
A47L 13/16
A47L 9/10

US Classification:

15320, 134201, 15347, 701200, 15245, 901 47

Abstract:

A surface treatment robot includes a chassis having forward and rear ends and a drive system carried by the chassis. The drive system includes right and left driven wheels and is configured to maneuver the robot over a cleaning surface. The robot includes a vacuum assembly, a collection volume, a supply volume, an applicator, and a wetting element, each carried by the chassis. The wetting element engages the cleaning surface to distribute a cleaning liquid applied to the surface by the applicator. The wetting element distributes the cleaning liquid along at least a portion of the cleaning surface when the robot is driven in a forward direction. The wetting element is arranged substantially forward of a transverse axis defined by the right and left driven wheels, and the wetting element slidably supports at least about ten percent of the mass of the robot above the cleaning surface.

International Classification:

G06F 17/00

US Classification:

700259, 700258, 901 1, 901 47

Abstract:

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.
