Abstract: A roller assembly for a mobile cleaning system for cleaning a work surface can include a drive shaft, a sheath, a bushing, and a bushing shroud. The drive shaft can be rotatable about a drive axis, and the drive shaft can include a driven end and an opposite bushing end. The sheath can be supported by the drive shaft and the sheath can be rotatable with the drive shaft. The sheath can include a shell engageable with the work surface. The bushing can be located about the bushing end of the drive shaft. The bushing shroud can be connected to the bushing. The sheath and the drive shaft can be together rotatable with respect to the bushing and the bushing shroud, the bushing shroud can include an outer portion defining a first radius of curvature and a recessed portion connected to the outer portion.

Abstract: A mobile robot includes a recessed well in a top surface of the mobile robot, at least one capacitive sensor underlying the recessed well and having a first region and a second region, one or more mobility sensors, and a controller coupled to the at least one capacitive sensor and the one or more mobility sensors. The controller is configured to determine an operating status of the mobile robot responsive to output signals from the one or more mobility sensors, and selectively disregard an input at a first portion of the recessed well corresponding to the first region of the at least one capacitive sensor based on the operating status of the mobile robot.

Abstract: A mobile cleaning robot can include a body, a drive wheel, and a wheel stop. The drive wheel can be connected to the body and can be operable to move the mobile cleaning robot about an environment. The wheel stop can be movable with respect to the body and the drive wheel between a stop position and a release position. The wheel stop can be engageable with the drive wheel in the stop position to limit vertical travel of the drive wheel with respect to the body.

CPC classification number: A47L9/0494 , A47L2201/00
Abstract: A mobile cleaning robot can be movable within an environment. The mobile cleaning robot can include a body, a cleaning head, a biasing element, and a linkage. The cleaning head can be operable to extract debris from a floor surface and can be configured to move vertically relative to the body between an extended position and a retracted position. The biasing element can be connected to the body and can be movable with the cleaning head. The linkage can be connected to the cleaning head and the biasing element. The linkage can be rotatably connected to the body to, together with the biasing element, bias the cleaning head toward the retracted position.
