A guide-type virtual wall system is provided. The system comprises a beacon (11, 44) and a robot (12), wherein a transmission module of the beacon (11, 44) directionally transmits a first signal, and an area covered by the first signal defines a beacon signal area (13). The robot (12) comprises a beacon signal receiving module corresponding to the beacon signal transmission module. When the robot (12) enters the beacon signal area (13) and the beacon signal receiving module detects the first signal, the robot (12) advances towards the direction of the beacon (11, 44) until it detects a second signal, and then the robot (12) crosses over or exits from the beacon signal area (13). The system can restrict the robot (12) from entering a certain area, wherein the area where a virtual wall is located is not missed, and the robot (12) is also enabled to cross over the virtual wall to enter the restricted area when required.

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 cleaning device for cleaning a surface is described. The cleaning device includes at least one cleaning element and a wetting system to supply a cleaning liquid to the at least one cleaning element. The wetting system is operable in one of at least one normal operation mode and a boost operation mode involving an increased supply rate of the cleaning liquid with respect to the at least one normal operation mode. During start-up of the cleaning device in a wet cleaning mode thereof, a start-up operation mode of the wetting system is determined to be one of the normal operation mode or the boost operation mode on the basis of assessment of an actual value of at least one parameter that is indicative of whether or not the at least one cleaning element is in a wet cleaning condition.
