A coverage robot including a chassis, multiple drive wheel assemblies disposed on the chassis, and a cleaning assembly carried by the chassis. Each drive wheel assembly including a drive wheel assembly housing, a wheel rotatably coupled to the housing, and a wheel drive motor carried by the drive wheel assembly housing and operable to drive the wheel. The cleaning assembly including a cleaning assembly housing, a cleaning head rotatably coupled to the cleaning assembly housing, and a cleaning drive motor carried by cleaning assembly housing and operable to drive the cleaning head. The wheel assemblies and the cleaning assembly are each separately and independently removable from respective receptacles of the chassis as complete units.

A method of operating a mobile robot includes generating a segmentation map defining respective regions of a surface based on occupancy data that is collected by a mobile robot responsive to navigation of the surface, identifying sub-regions of at least one of the respective regions as non-clutter and clutter areas, and computing a coverage pattern based on identification of the sub-regions. The coverage pattern indicates a sequence for navigation of the non-clutter and clutter areas, and is provided to the mobile robot. Responsive to the coverage pattern, the mobile robot sequentially navigates the non-clutter and clutter areas of the at least one of the respective regions of the surface in the sequence indicated by the coverage pattern. Related methods, computing devices, and computer program products are also discussed.

A cleaning roller is mountable to a cleaning robot. The cleaning roller includes a sheath comprising a shell, an outer diameter of the shell tapering from a first end portion of the sheath and a second end portion of the sheath toward a center of the roller. The cleaning roller further includes a core including a central portion interlocked with the sheath to rotationally couple the core to the sheath and inhibit relative translation of the sheath and the core along an axis of rotation. An inner surface of the sheath and an outer surface of the core define an air gap therebetween, the air gap extending from the central portion of the core longitudinally along the axis of rotation toward the first end portion or the second end portion.

A method and apparatus for identifying a ground feature by an automatic cleaning device. The method comprises: collecting a rolling-brush current and a side-brush current (S10); performing weighted calculation according to the rolling-brush current and the side-brush current, so as to obtain a ground identification coefficient (S20); and according to the ground identification coefficient, identifying a feature of whether the ground on which the automatic cleaning device is located is carpet or a non-carpet dielectric surface (S30). Software optimization is carried out on the basis of current detection technology, thus reducing the false identification rate without additional cost.

The present invention provides a vacuum cleaner brush head and a dust collection method. The vacuum cleaner brush head includes a brush head body, a front wiping plate, a rear wiping plate, a wiping plate driving device, and a water spraying assembly; a dust collection pipe is provided in the brush head body; the dust collection pipe has a dust collection port formed on the front side of the bottom of the brush head body; a water spraying port of the water spraying assembly is provided on the bottom of the brush head body and located between the front wiping plate and the rear wiping plate; the wiping plate driving device is transmittingly connected to the front wiping plate and the rear wiping plate, and is configured to drive the front wiping plate and the rear wiping plate to move reciprocally in opposite directions

An autonomous cleaning robot includes a drive system to support the autonomous cleaning robot above a floor surface, an image capture device positioned on the autonomous cleaning robot to capture imagery of a portion of the floor surface forward of the autonomous cleaning robot, and a controller operably connected to the drive system and the image capture device. The drive system is operable to maneuver the autonomous cleaning robot about the floor surface. The controller is configured to execute instructions to perform operations including initiating, based on a user-selected sensitivity and the imagery captured by the image capture device, an avoidance behavior to avoid an obstacle on the portion of the floor surface.

An intelligent vacuum device is provided. A main body of the vacuum device has a dust bin and a main vacuum port formed on a bottom side thereof and communicated with the dust bin. An extendable suction arm is switchable relative to the main body between a first position and at least one second position. The extendable suction arm has at least one actuator and at least one arm vacuum port thereon, and the arm vacuum port is communicated with the dust bin. At least one detection sensor is disposed on the main body to detect a surrounding environment of the vacuum device and generate corresponding sensing signals. A controller is used to control movement of the vacuum device based on the sensing signals, and control the at least one actuator to switch the extendable suction arm between the first position and the at least one second position.

A robotic vacuum cleaner includes a main body having an underside configured to face a surface to be cleaned, a suction opening that opens into the underside of the main body and extending transversely to a main direction of travel of the robotic vacuum cleaner; and a first side cleaning member attached at a fixed location on a front part of the main body and located adjacent a first side edge of the main body, the first side cleaning member having a first cleaning part which is flexible and is configured to direct waste, which comes into contact with the first cleaning part when the robotic vacuum cleaner moves in the main direction of travel, toward the suction opening.
