The invention is in the field of a cleaning machine for a road or pavement or gutter. These machines are used to remove objects, such as small items, such as leaves, and dirt from a road or the like, using a broom system for cleaning the road or the like, and typically a storage for removed objects and dirt.

A cleaner hanger assembly, comprising a hanger (30), a charging bottom plate (20), an accessory frame (40), a hanger column (50) and a base (60). The charging bottom plate (20) can be used in cooperation with the hanger (30), so that a charging operation can be performed while the cleaner is hung on the hanger (30) whether when the cleaner is in a hanging state or in a floor-standing state, and the charging bottom plate (20) can also be detached for separate use. The hanger (30) can be connected to the accessory frame (40) to form a wall hanger assembly; or the hanger (30) can be connected to the base (60) by means of the hanger column (50), and the accessory frame (40) is fixed in the middle of the hanger column (50) to form a floor-standing hanger assembly.

Disclosed are a cleaning module and a cleaner comprising same. The cleaning module, according to one aspect of the present specification, comprises: a housing communicating with a suction port of a main body of the cleaner, and comprising a suction space exposed to a bottom surface; a first hole disposed on one side surface, perpendicular to a cleaning direction, of the housing; and a first opening/closing device comprising a first shielding member for enabling communication with the suction space by selectively opening/closing the first hole.

A portable surface cleaning apparatus has a main body and air treatment member assembly is removably mounted to the main body. The air treatment member assembly air outlet and/or the suction motor inlet end is provided at the lower end of the air treatment member assembly when the surface cleaning apparatus is located on a floor and a pre-motor filter underlies the air treatment member assembly and/or the suction motor.

A method of controlling movement of a robotic cleaning device over an area to be cleaned. The method includes acquiring a visual representation of the robotic cleaning device on a display of a wireless communication device, identifying the robotic cleaning device in the visual representation, computing a coordinate transform between the visual representation and a robotic cleaning device coordinate system, creating an instruction by receiving user-indicated spatial information on the display or how the robotic cleaning device should move over the area to be cleaned, applying the transform to the spatial information, transforming the spatial information to the robot coordinate system, and sending the instruction to the robotic cleaning device via wireless communication, to cause the robotic cleaning device to move over said area in accordance with the transformed spatial information.

A mobile cleaning robot can include a body, a drive wheel, and a plurality of skids. The drive wheel can be connected to the body and can be engageable with a floor surface of an environment. The drive wheel can be operable to move the mobile cleaning robot about an environment. The skids can be separate skids that can be connected to the body and can be engageable with the floor surface to support, together with the drive wheel, the mobile cleaning robot with respect to the floor surface.

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.

An optical navigation device comprising: a processing circuit; a first light source, configured to emit first light; a cover; at least one second light source, configured to emit second light toward the cover; and an first optical sensor, configured to sense first optical data generated according to the first light and to sense second optical data generated according to the second light on the cover. The processing circuit determines a dirtiness level of the cover based on the second optical data sensed by the first optical sensor. The optical navigation device can further comprise a second optical sensor. Also, an optical navigation device which can avoid the interference of another optical navigation device is also disclosed.

The invention pertains to a system consisting of a first floor treatment apparatus that is exclusively guided manually within an environment by a user and a second floor treatment apparatus that is exclusively operated automatically, wherein the second floor treatment apparatus is designed for orienting and localizing itself within an environment. The first floor treatment apparatus is designed for detecting a movement path of the first floor treatment apparatus during a movement of the first floor treatment apparatus that is manually guided by a user, as well as for transmitting information on the detected movement path to the second floor treatment apparatus by means of wireless communication. The second floor treatment apparatus is designed for receiving the information and for autonomously traveling along the movement path within the environment based on the received information.

A cleaner holder comprises a base, a stand coupled to the base and extending upward from the base, a support body coupled to an upper portion of the stand and configured to support a cleaner, and a cleaning module support coupled to the stand and configured to support a cleaning module of the cleaner. The cleaning module may be detachably coupled to an extension tube of the cleaner.
