Provided is a cleaning system including: a robot cleaner including a dust collecting device having a dirt outlet and an outlet door configured to open and close the dirt outlet; and a station including a collecting device configured to generate a suction force to suction dirt of the duct collecting device and a lever device provided with a lever configured to be fixable to the outlet door as the outlet door is being opened to allow the collecting device and the dust collecting device to communicate with each other, and a lever driving source configured to generate power for driving the lever.

A docking station, a mobile robot, and a mobile robot management method for controlling a docking station and a mobile robot are provided. The mobile robot includes a management method wherein, in order to display information associated with a docking station to an output device of a mobile robot or transmit the information to a user terminal device connected to the mobile robot, the mobile robot transmits, to the user terminal device, information received from the docking station.

An artificial intelligence (AI) cleaner according to an embodiment of the present invention may include a memory, a movement detect sensor, a driving unit configured to allow the AI cleaner to be moved, and a processor configured to control the movement sensor to sense a movement of the AI cleaner by a user and acquire a position to which the AI cleaner has moved while the AI cleaner operates at a first cleaning mode and control the driving unit to allow the AI cleaner to clean a priority cleaning area corresponding to the position at a second cleaning mode.

An optical beacon may include a housing, an optical emitter at least partially disposed within the housing, and an optical identifier generator optically coupled to the optical emitter. Light incident on the optical identifier generator may be shaped into at least one optical identifier. The optical identifier may be associated with an action capable of being carried out by a robotic cleaner such that detection of the optical identifier by the robotic cleaner causes the robotic cleaner to carry out the action.

An air purifying system includes a robot cleaner configured to generate map information during vacuum cleaning and at least one air purifier that is operated based on the generated map information. Air purifying is performed using updated map information acquired by the robot cleaner during cleaning. The at least one air purifier includes two portable air purifiers mounted on a base air purifier. The two portable air purifiers are configured to be lifted from the base air purifier and moved to separate indoor rooms. The base air purifier includes a controller that determines, based on the generated map information and other information, which rooms the two portable air purifiers should be placed in so that air purifying may be efficient.

The disclosure relates to a cleaning robot, controlling method thereof, and cleaning robot charging system, and more particularly, to a technology for a cleaning robot to select a charging device by taking into account whether the charging device is occupied and a distance to the charging device when the charging device is returning to the charging device for charging. The cleaning robot includes a main body; a movement module moving the main body; a communication module configured to request identification information of a charging device occupied by another cleaning robot to the other cleaning robot; and a controller configured to determine a charging device not occupied by the other cleaning robot based on the identification information of the charging device received from the other cleaning robot through the communication module, and to control the movement module to move the main body to the non-occupied charging device.

Provided is a charging device for charging a wireless manual cleaner and a robot cleaner. The charging device includes a first charger comprising a first charging terminal connected to a charging terminal of the manual cleaner, and a first transceiver configured to transmit and receive information to and from the manual cleaner; a second charger comprising a second charging terminal connected to a charging terminal of the robot cleaner, and a second transceiver configured to transmit and receive information to and from the robot cleaner; and a communication line configured to electrically connect the first transceiver and the second transceiver to each other.

Some aspects include a schedule development method for a robotic floor-cleaning device that recognizes patterns in user input to automatically devise a work schedule.

A mobile robot and a control method therefor, according to the present invention, are configured to determine whether a received signal is a pre-set signal and distinguish noise caused by overlapping of signals to control the operation of a sensor for detecting an obstacle according to an operation state of a main body such that transmission of a detection signal is limited, and thus has effects of the obstacle being easily detected by distinguishing each signal, the main body returning to a charging stand, and signal interference being minimized for a plurality of sensors using a signal of the same wavelength band.

A multi-robot system includes a first a mobile cleaning robot that has a local storage device to store a persistent map of an environment, at least one sensor to sense the environment, and a control module. The control module is configured to: control the mobile cleaning robot to navigate in the environment using the persistent map and sensing data provided by the at least one sensor, share the persistent map with a second mobile cleaning robot, and coordinate with the second mobile cleaning robot to perform cleaning tasks.
