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 vacuum assembly includes a vacuum portion having a vacuum source with an inlet and an outlet and a tank portion. A three-way inlet valve fluidly connects the inlet to the vacuum source with the tank portion when in a first position and fluidly connects the inlet to the vacuum source with an inlet to a surrounding environment when in a second position. A three-way outlet valve fluidly connects the outlet of the vacuum source with an outlet to the surrounding environment when in a first position and the outlet of the vacuum source with the tank portion when in a second position.

A disposal bag for a vacuuming device, wherein the disposal bag has a pressure equalization matrix. The pressure equalization matrix has openings that are designed to effect pressure equalization between a first region and a second region of a collecting tank of the vacuuming device. The vacuuming device can preferably be a construction site vacuum cleaner, wherein the collecting tank of the vacuuming device is designed to receive the disposal bag and the dust sucked in by the vacuuming device is collected and contained in the disposal bag. A method for producing a disposal bag, and to the use thereof in a vacuuming device is also provided.

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.

The present application discloses a cleaning device and its dust box. The cleaning device may comprise a body, a dust box, and at least two fans. The dust box may be provided for connection to the body, the at least two fans are provided in the body for forming an airflow into and out of the dust box through the apparatus body. The dust box may be provided such that the airflow formed by each of the at least two fans can flow out of the dust box in different directions.

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 robotic vacuum cleaner is provided having a suction source, a dirt collector, a floor sensor, a primary brush, and an auxiliary brush. The floor sensor includes an emitter and a detector having an intersecting region. The auxiliary brush includes microfiber fingers that are spaced around a perimeter of the brush, or the auxiliary brush includes a pad having apertures, the apertures allow the emitter and detector to sense whether a floor surface is present.
