A cleaning device and a method therefor are provided. The cleaning device includes a vacuum cleaner including a dust collecting container and a docking station to which the dust collecting container is coupled. The docking station includes a suction device configured to move air from the dust collecting container to inside of the docking station, a collector configured to collect a foreign substance that is moved together with the air by driving of the suction device, a suction flow path along which air moves inside the docking station, a flow adjusting device configured to open or close the suction flow path, and at least one processor configured to control the suction device to operate based on the dust collecting container being coupled to the docking station, and control the flow adjusting device to periodically open and close the suction flow path in a state in which the suction device operates.

A vacuum cleaner including a suction inlet, a conduit in fluid communication with the suction inlet, a filter having a valve releasably connected to a filter inlet, the filter configured to collect debris drawn through the suction inlet. The vacuum cleaner further comprising a release mechanism moveable from a first position to a second position. In the first position, the filter is in fluid communication with the conduit to collect debris with the valve being open, and in the second position, the filter is disconnected from the conduit with the valve being closed. Movement of the release mechanism between the first and second positions closes the valve.

An all in the head surface cleaning apparatus can include a surface cleaning head having an air flow path extending from a dirty air inlet to a clean air outlet. The surface cleaning head can include a cyclone assembly comprising a cyclone chamber and a dirt collection chamber. The cyclone chamber may have a longitudinal cyclone axis, a cyclone air inlet and a cyclone air outlet. The dirt collection chamber may be moveable between an in use position and an emptying position. The surface cleaning head may include a pre-motor filter chamber and a suction motor. At least one of the pre-motor filter and a pre-motor filter chamber may be visible when the dirt collection chamber is in the emptying position. An upper portion may be mounted to the surface cleaning head between a storage position and a floor cleaning position, and may include a drive handle.

Disclosed are related to a dust collecting apparatus, a cleaning apparatus, and a method of controlling the cleaning apparatus. The dust collecting apparatus may comprises a dust collecting space configured to collect impurities and a variable body formed to surround the dust collecting space and having one of transparency, shape and color changed by selectively transmitting or reflecting light in response to applied electric power.

A vacuum cleaner includes a dirt separating and collecting system. The dirt separating and collecting system can include an air-permeable filter material, and a helical inlet guide. Dirt entering the helical inlet guide within a working airstream is visible to the user through an at least partially transparent housing.

An autonomous coverage robot includes a chassis, a drive system configured to maneuver the robot, and a cleaning assembly. The cleaning assembly includes a cleaning assembly housing and at least one driven sweeper brush. The robot includes a controller and a removable sweeper bin configured to receive debris agitated by the driven sweeper brush. The sweeper bin includes an emitter disposed on an interior surface of the bin and a receiver disposed remotely from the emitter on the interior surface of the bin and configured to receive an emitter signal. The emitter and the receiver are disposed such that a threshold level of accumulation of debris in the sweeper bin blocks the receiver from receiving emitter emissions. The robot includes a bin controller disposed in the sweeper bin and monitoring a detector signal and initiating a bin full routine upon determining a bin debris accumulation level requiring service.

A robot cleaner is provided that may include a suction motor installed within a main body to generate a suction force, at least two conductive plates spaced apart from each other to form a flow path for external air introduced by the suction force, and a calculator to measure a capacitance value between the at least two conductive plates. Further, provided is a robot cleaner that may include a suction motor installed within a main body to generate a suction force, a porous structure having at least one through hole, through which external air introduced by the suction force may flow, at least one filter disposed on a surface of the porous structure to filter dust contained in the air, and a power supply configured to apply alternating current (AC) power to at least a portion of the surface of the porous structure.
