A robot cleaner according to the present invention includes a body provided with a driving unit for movement, a position recognition unit provided in the body to recognize a position of the body, a storage unit configured to store, on a map, a region cleaned while the body is moving by the driving unit, and a control unit configured to control the driving unit, wherein the control unit determines whether a charging stand exists in a cleaning completed region on the map stored in the storage unit when a return condition that the body returns to the charging stand is satisfied, searches for an uncleaned region when the charging stand is not located in the cleaning completed region, and controls the driving unit such that the body moves from a current position to a point in a found uncleaned region or a point around the found uncleaned region.

A docking station for a mobile cleaning robot can include a base portion configured to receive the mobile cleaning robot. The docking station can include a housing connected to the base portion and a pad cleaning system. The pad cleaning system can be connected to the housing and can include a cleaning head engageable with a cleaning pad of the mobile cleaning robot to remove debris from the cleaning pad, the cleaning head can include a nozzle configured to discharge a fluid onto the cleaning pad.

A docking station for a mobile cleaning robot can include a housing. The housing can define or comprise a pad receptacle and a pad dispenser. The pad receptacle can be configured to receive a soiled pad from a pad tray of the mobile cleaning robot. The pad dispenser can be configured to provide a fresh pad to the pad tray of the mobile cleaning robot.

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.

An apparatus for use with a plurality of robotic appliances, the apparatus comprising a plurality of receiving spaces each configured to receive at least one robotic appliance, wherein each of the receiving spaces comprises: a shelf comprising an upper surface on which a robotic appliance can be located; a charging element configured to charge a robotic appliance when it is located on the shelf; and one or more locating formations arranged to abut said robotic appliance, such that the one or more locating formations provide support against movement of the robotic appliance when the robotic appliance is located on the shelf, wherein the one or more locating formations are provided at or above the upper surface of said shelf.

A vacuum cleaner assembly includes a vacuum body, a suction wand removably connected to the vacuum body, and an accessory removably connected to the suction wand. A suction motor is disposed in the vacuum body and is configured to create flow through a suction path. An accessory motor is disposed in the accessory. A first power source is configured to supply power to the suction motor and to the accessory motor. A second power source is configured to supply power to the suction motor and to the accessory motor when the first power source falls below a predetermined charge level.

A cleaner performing autonomous traveling includes a main body, a driving unit moving the main body, a battery supplying power to the driving unit, a communication unit performing communication with a charging station to charge the battery, a sensor sensing a signal emitted from the charging station, and a controller controlling the driving unit such that the main body is docked to the charging station on the basis of the signal sensed by the sensor, wherein when the main body starts to move to dock to the charging station, the controller determines a kind of the signal sensed by the sensor and controls the driving unit such that the main body moves along a traveling path corresponding to a circle centered on a predetermined point on the basis of the determined kind of the signal.

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.
