A cleaning system includes: a cleaning appliance comprising a base member, which is provided with a mechanical cleaning arrangement, and a fluid tank; and a cleaning apparatus for cleaning the mechanical cleaning arrangement of the cleaning appliance, the cleaning apparatus including: a container having a recess for receiving the base member; and a nozzle arrangement associated with the recess. The nozzle arrangement is connected to an inlet in a flow-conducting manner. The fluid tank has an outlet which, to clean the cleaning arrangement, is connectable to the inlet of the cleaning apparatus.

A cleaning area estimation device (30) includes an estimation unit (33) that estimates dirt information (D2) about an inside of a cleaning area on the basis of image information (D1) obtained by imaging a cleaning area by an imaging device (10), and a generation unit (34) that generates map information (D3) indicating a map of the dirt information about the cleaning area on the basis of the estimated time-series dirt information (D2).

Disclosed is a robot cleaner including a main body forming an outer shape, a water tank including a water level sensor and storing water, a pair of rotary mops to which a cleaning cloth is attached, and that moves the main body while rotating in contact with a floor, a drive motor rotating the pair of rotary mops, a nozzle supplying water from the water tank to the cleaning cloth of the rotary mop, and a controller periodically determining an abnormality in water supply to convert to a wet mop mode or to a dry mop mode to proceed with cleaning. Therefore, in the present disclosure, the sensor may be provided in the water tank to detect the water shortage in the water tank for supplying water to the rotary mop, thereby determining whether to change modes by the robot cleaner itself.

A robot device includes: a sensor configured to generate sensing data related to an action of the robot device; a communication interface configured to communicate with a server; a memory storing instructions; and a processor configured to execute the instructions to: based on the action of the robot device changing, store action data in the memory, the action data including instruction data corresponding to the action, the sensing data related to the action, and map data related to the action, transmit, to the server via the communication interface, the action data stored in the memory, receive, from the server via the communication interface, threshold data corresponding to the action, and based on identifying that the sensing data is outside of a threshold range based on the threshold data received from the server, generate an event.

Some autonomous cleaning robots include a drive configured to maneuver the autonomous cleaning robot about a floor surface. The robots include a cleaning system to clean the floor surface as the autonomous cleaning robot is maneuvered about the floor surface. The robots include a robot button positioned on the autonomous cleaning robot. The robots include a controller in electrical communication with the drive and the robot button. The controller is configured to perform operations including selecting a behavior of the autonomous cleaning robot from a plurality of behaviors of the autonomous cleaning robot responsive to a duration of actuation of the robot button and causing the autonomous mobile robot to initiate the behavior.

A self-cleaning automatically-stored electrical mop includes a mop rod assembly, a mop head assembly, and a cleaning base assembly used for storing and cleaning the mop head assembly. The mop head assembly is arranged at the lower end of the mop rod assembly and includes a mop head shell which is provided with a rotatable cleaning roller and a motor used for driving the cleaning roller. The cleaning base assembly includes a shell part. A cleaning groove used for cleaning the cleaning roller is formed in the shell part, and a cleaning assembly used for scrubbing the cleaning roller is arranged in the cleaning groove. The shell part is provided with a sewage discharge system used for discharging sewage.

A cleaning robot includes a main body having an exterior portion extending along a perimeter of the main body; wheels that are drivable to move the robot; a rotation shaft; and a holder coupled to the rotation shaft to support a cleaning pad. The rotation shaft and the holder are rotatable along a rotation axis that is perpendicular to the surface to be cleaned, and the rotation shaft is laterally movable in a direction perpendicular to the rotation axis to: a pop-in position in which the rotation shaft and the holder are under the main body and not protruding beyond the exterior portion of the main body, and a pop-out position in which the rotation shaft is under the main body and not protruding beyond the exterior portion and the holder is partially under the main body and partially protruding beyond the exterior portion of the main body.

There is provided a cleaning robot including a light source module, an image sensor and a processor. The light source module projects a line pattern and a speckle pattern toward a moving direction. The image sensor captures an image of the line pattern and an image of the speckle pattern. The processor calculates one-dimensional depth information according to the image of the line pattern and calculates two-dimensional depth information according to the image of the speckle pattern.
