Industrial vacuum cleaner configured for servicing at least one construction tool, said vacuum cleaner comprising a vacuum inlet, wherein said vacuum cleaner further comprises a controller and connected to said controller a wireless transceiver, a memory, and at least one location and/or orientation sensor configured for detection of vacuum cleaner location and/or localization of other objects in relation to the vacuum cleaner and wherein the vacuum cleaner further comprises means for propulsion controlled by said controller.

A wheel assembly for a robotic cleaner may include a frame, a moveable arm pivotally coupled to the frame, a driven wheel rotatably coupled to the moveable arm such that the driven wheel pivots with the moveable arm, and a biasing mechanism configured to urge the driven wheel towards an extended position, the biasing mechanism being coupled to the frame and spaced apart from the moveable arm.

A mobile robot includes a body and a rotating plate rotatably installed on the body. A mop portion is attached to a lower surface of the rotating plate. And, a rotating ball that is vertically aligned with a rotating shaft of the rotating plate is rotatably installed on the rotating plate.

An autonomous coverage robot includes a cleaning assembly having forward roller and rearward rollers counter-rotating with respect to each other. The rollers are arranged to substantially maintain a cross sectional area between the two rollers yet permitting collapsing therebetween as large debris is passed. Each roller includes a resilient elastomer outer tube and a partially air-occupied inner resilient core configured to bias the outer tube to rebound. The core includes a hub and resilient spokes extending between the inner surface of the outer tube and the hub. The spokes suspend the outer tube to float about the hub and transfer torque from the hub to the outer tube while allowing the outer tube to momentarily deform or move offset from the hub during impact with debris larger than the cross sectional area between the two rollers.

A Method for cleaning air in a room (1) with a ceiling (3) and a floor (5), comprising moving an ionization unit (13) above the floor (5) along a support structure provided at a distance to the floor (5); and electrically charging particles in the air by the ionization unit (13).

A cleaning robot control method, applicable to a cleaning robot, includes: obtaining a network status of the cleaning robot and performing a preset action when the network status is a network-disconnected state or a network signal intensity is lower than a preset signal intensity threshold. A computer-readable storage medium and a cleaning robot are further provided.

A vehicle includes a wheel to contact a surface having a reference surface plane in operation of the vehicle; a chassis; an axle housing having an axis which is normal to the reference surface plane; and an axle. The axle extends from the axle housing, to couple the wheel to the axle housing and to support rotation of the wheel relative to the axle housing to support motion of the vehicle across the surface in operation of the vehicle. A suspension system couples the wheel to the chassis and includes a linkage assembly having a first end pivotably coupled to the chassis and a second end pivotably coupled to the axle housing. The first end of the linkage assembly is spaced apart laterally from the second end of the linkage assembly along a longitudinal axis of the linkage assembly. The suspension system is configured to maintain the axis of the axle housing at an angle normal to the reference surface plane in response to an angular displacement between the chassis and the reference surface plane.

A mobile disinfection device (200) includes a disinfection chamber (203) coupled to a propulsion system (228) configured for moving along a surface (236) to be disinfected. The disinfection chamber defines a closed distal end (205), an open proximal end (206) and a surrounding wall (207) impervious to the radiation and having opposing front and rear portions and opposing side portions, respective proximal front, rear and side edges of which are propelled by the propulsion system close to the surface to be disinfected. A radiation source (260) is mounted inside the disinfection chamber for irradiating the surface through the open proximal end. The propulsion system includes a peripheral seal (304) surrounding a proximal edge of the wall and configured to obstruct radiation that might otherwise escape from inside the disinfection chamber.

Disclosed herein are a wheel assembly and a robot cleaner including a main body and a wheel assembly coupled to the main body to guide movement of the main body. The wheel assembly has a rotation arm including a first end portion rotatably mounted on the main body, a drive wheel rotatably installed on a second end portion of the rotation arm opposite the first end portion, and an elastic member including a first end installed at the main body and a second end vertically moveably installed at the rotation arm opposite the first end, such that a reduction degree of a contact force due to a descent of the drive wheel.

A method of removing mites includes: acquiring a target path for mite removal and switching from a hibernation state to a crawling state upon receiving a mite removing instruction; in the crawling state, crawling according to the target path and performing mite removal during the crawling process; and after crawling to an end position of the target path, switching from the crawling state to the hibernation state.
