A method for operating a base station for a cleaning device is proposed, wherein exclusively by means of a pressure sensor and/or by means of a differential pressure the filling level of the container is determined as state of the base station and additionally at least one further state of the base station is determined and/or wherein on reaching a predefined filling level the maximum number of still possible extraction processes with-out emptying a container is limited.

A handheld vacuum cleaner includes: a suction unit provided with an air outlet end; a dust-gas separation unit detachably connected to one end of the suction unit; a handle connected to another end of the suction unit; and an air outlet filter unit detachably disposed on an outside of the suction unit along an axial direction of the handle; wherein the air outlet filter unit is disposed at the air outlet end.

A cleaning device including a cleaner and a station on which the cleaner is mounted is provided. The cleaner includes a suction head, a dust container to collect dust contained in air vacuumed through the suction head, and an extension tube connecting the suction head with the dust container. The station includes a main body configured to suck dust of the dust container of the cleaner and contain the dust, a support configured to support the main body and guide rotation of the main body, and a rotation driving device disposed in the support and configured to transmit a rotational force to the support.

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 cleaner includes a housing, a body slidably coupled to the housing, a dust container mountable to the housing and detachable from the housing, and a pushing device slidably coupled to the dust container and mountable to the body and detachable from the body.

A vacuum cleaner comprises: a housing and a motor fan assembly mounted in the housing, the motor fan assembly arranged to generate an air flow. A removable dirt container is mountable on the housing and in fluid communication with a dirty air inlet and the motor fan assembly. A moveable dirt compactor is mounted in the dirt container and moveable between a stowed position and a dirt compacting position wherein the moveable dirt compactor is closer to one end of the dirt container in the dirt compacting position than in the stowed position. Wherein the dirt container comprises a primary handle for actuating the moveable dirt compactor with a first hand and a first auxiliary handle for allowing the user to grip with a second hand.

Disclosed is a linkage limiting assembly applied in a vacuum cleaner, which is mounted within a frame of the vacuum cleaner. The linkage limiting assembly includes a triggering button arranged at the rear end of the frame, a pushing member configured to push an electric fan assembly or a dust barrel of the vacuum cleaner upwards, a limiting member configured to limit the maximum stroke of the electric fan assembly or the dust barrel, and a linking member connecting the triggering button with the limiting member in a force transmission manner.

A cleaner is provided. The cleaner includes a transfer device, and a dust collecting apparatus connectable to the transfer device and configured to filter out rubbish transferred from the transfer device. The dust collecting apparatus includes a housing in which a first dust chamber is formed, and including a guide recessed inwardly from an outer surface, a handle configured to be movable on the outside of the housing and provided to cover at least a portion of the guide, a first rubbish removal member configured to be movable inside the housing based on the movement of the handle, and configured to discharge rubbish collected in the first dust chamber, and a link configured to connect the handle to the first rubbish removal member, and having a movement guided by the guide.

A surface cleaning apparatus has a housing defining at least part of a cyclone chamber and a pre-motor filter chamber. In one embodiment, the housing is pivotally mounted to the main body of a hand vacuum cleaner. The housing is moveable between an in use position and an emptying position, in which the cyclone chamber and the pre-motor filter are concurrently openable.
