A water supply mechanism and an automatic cleaning apparatus are provided. The water supply mechanism is applicable for a wet cleaning assembly of a cleaning device, comprising a water outlet device, wherein the water outlet device is connected to a cleaning liquid outlet of a water tank, and a cleaning liquid in the water tank flows to the water outlet device through the cleaning liquid outlet of the water tank and is transported to a surface to be cleaned through the water outlet device.

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.

A detachable structure and a self-moving robot are provided. The detachable structure is provided in a self-moving robot including a wet cleaning apparatus. The wet cleaning apparatus includes a housing and a cleaning assembly disposed in the housing, and the detachable structure includes: a pressure plate having a connection end and a movable end. The movable end is adjustably clamped to the housing. When the movable end and the housing are in a clamped state, the movable end blocks a partial structure of the cleaning assembly such that the cleaning assembly abuts against the housing; and when the movable end and the housing are in a non-clamped state, the cleaning assembly is removable from the housing.

Disclosed is a robot cleaner including: a main body forming an outer shape; a pair of rotary mops moving the main body while rotating in contact with a floor; a drive motor rotating the pair of rotary mops; a pump connected to a water tank and driving a nozzle for spraying water to the rotary mop; and a controller for determining water content of the rotary mop in a preliminary step before wet cleaning, and controlling to start the wet cleaning after driving the pump until the water content of the rotary mop satisfy a certain level. Accordingly, it is possible to detect a change in the output current of the motor of the rotary mop of the robot cleaner and determine the water content according to the change in the current value.

An autonomous apparatus, such as an autonomous robot, maintains wood decks by automatically cleaning and staining the deck while traversing the deck in a manner so that the cleaning and staining is performed in accordance with an organized navigation pattern along the deck boards.

Disclosed are a cleaning roller and a rolling steam mop. The cleaning roller includes a central shaft capable of rotating, a steam channel, and a cleaning layer. The steam channel is provided with a steam inlet and a plurality of first steam outlets; the steam inlet is used for communicating with a steam generation device: the plurality of first steam outlets are distributed in an axial direction of the central shaft. The cleaning layer is provided around the central shaft; and the steam flowing out from the first steam outlets can be diffused outwards through the cleaning layer When in use, the steam generated by the steam generation device enters the steam channel through the steam inlet, and then flows out from the first steam outlets, and is diffused outwards through the cleaning layer, so that the steam can be diffused to an object to be cleaned.

A mobile mechanism, a mobile robot having the mobile mechanism and a method for moving the mobile robot are disclosed. The mobile mechanism includes a housing in which a guide portion is provided, a sliding seat mounted on the guide portion and movable along the guide portion, a moving wheel fixed on the sliding seat and partially protruding beyond a surface of the housing, a pressing portion pressing against the sliding seat and moving the sliding seat toward the surface of the housing; and a deformation portion mounted on the housing and connected with the pressing portion, exerting a force for moving the sliding seat towards the surface of the housing through the pressing portion when deformed.

A cleaning machine may include: a drive shaft; a rotation transmitting mechanism configured to transmit rotation of the drive shaft; a brush attaching member configured to rotate about a rotation axis; a clutch mechanism coupling the rotation transmitting mechanism with the brush attaching member; a brush attached to the brush attaching member; and a brush moving mechanism configured to move the brush attaching member between an adjacent position adjacent to a working plane and a distant position distanced from the working plane. The clutch mechanism may be configured to transmit the rotation from the rotation transmitting mechanism to the brush attaching member when the brush attaching member is at the adjacent position and cut off transmission of the rotation from the rotation transmitting mechanism to the brush attaching member when the brush attaching member is at the distant position.

Provided is a method for operating a robot, including capturing images of a workspace, comparing at least one object from the captured images to objects in an object dictionary, identifying a class to which the at least one object belongs using an object classification unit, instructing the robot to execute at least one action based on the object class identified, capturing movement data of the robot, and generating a planar representation of the workspace based on the captured images and the movement data, wherein the captured images indicate a position of the robot relative to objects within the workspace and the movement data indicates movement of the robot.

A self-propelled object-gathering apparatus includes a chassis, a drive system coupled to the chassis and configured to traverse the apparatus over a surface, and a receptacle coupled to the chassis. The apparatus also includes a sweep assembly coupled to the chassis and rotatable with respect to the chassis. The sweep assembly is configured to transfer objects from the surface into the receptacle by mechanical action on the objects, and without the use of negative pressure or vacuum suction acting on the objects during the transfer, in response to rotation of the sweep assembly.
