A vacuum cleaner includes an improved dual-action filter cleaning mechanism using both a rotational flicking action and a vertical shaking action. A debris removal assembly of the vacuum cleaner can include a filter assembly having a first filter and a second filter arranged in a nested configuration, and a filter cleaning mechanism configured to impart a combination of vertical shaking of the first filter and rotational flicking of the second filter. The filter cleaning mechanism can include a camming mechanism configured to simultaneously move the first filter along the axis and rotate the first filter about the axis while the second filter remains stationary.

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 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.

A stand for a cleaner is capable of holding and charging selectively a cleaner body or a battery. The stand for a cleaner includes a first charging terminal configured to be electrically connected to a cleaner body, a second charging terminal configured to be electrically connected to a battery, and a battery guide configured to guide the battery. The battery guide guides the cleaner body to be connected to the first charging terminal when the battery is mounted to the cleaner body, and is configured to guide the battery to be connected to the second charging terminal when the battery is separated from the cleaner body.

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.

A vacuum cleaner assembly basically includes a vacuum body, a first power source, an accessory, and a second power source. The first power source is configured to create flow through a suction path. The accessory is configured to be removably connected to the vacuum body. The second power source is configured to power the accessory. Each of the first and second power sources is configured to share power with the other of the first and second power sources.

A cleaner, according to one embodiment of the present invention, comprises: a cleaner main body comprising a suction motor, a dustbin and a battery; a suction nozzle having formed thereon an opening part for suctioning in external air; and an extension tube for connecting the cleaner main body and the suction nozzle. The suction nozzle comprises: a housing forming the exterior and the opening part of the suction nozzle; a rotational cleaning unit accommodated in the housing and cleaning a surface being cleaned by means of a rotational operation; a motor inserted in one side of the rotational cleaning unit so as to rotate same; a suction nozzle battery for supplying power for driving the motor; and a wireless power receiving unit connected to the suction nozzle battery so as to provide same with power supplied by an external wireless power transmission unit.

A backpack dust collector includes a housing, a slit portion, and a noise-absorbing member. The housing includes a suction port, a dust collecting chamber, a motor chamber, and an exhaust port. The dust collecting chamber is connected to the suction port and configured to accommodate a dust collecting bag. The motor chamber is connected to the dust collecting chamber and accommodates a fan and a motor. Through the exhaust port, air from the motor chamber is discharged. The slit portion is disposed in a flow path between the motor chamber and the exhaust port and includes at least one slit-shaped vent through which air from the motor chamber passes. The noise-absorbing member is disposed in at least part of a flow path between the vent and the exhaust port.
