An automatically moving robotic vacuum cleaner has a housing and a filter chamber for receiving suction material. The housing has a housing opening that is formed on the upper side of the housing and has a displaceable sealing element, which can be displaced from a closed position that closes the housing opening into a released position that releases the housing opening, so as to enable access to the filter chamber. The closure element can be mounted on the housing in a linearly movable manner. There is a detection device that is set up to detect the presence of an external vacuum cleaning apparatus to be connected with the housing opening in the area of the housing opening of the robotic vacuum cleaner. The robotic vacuum cleaner also has a control device that is set up to control an opening of the housing opening upon detection of the external vacuum cleaning apparatus.

A hand vacuum cleaner has a cyclone chamber formed of at least two axially extending cyclone chamber sidewall portions wherein one of the portions is pivotally openable. Once opened, a moveable member is translatable to clean or enable cleaning of a screen.

In a dust collector, an intake side surface on the intake portion side of a filter expands in a first direction, and extends in a direction including at least a component of a second direction. The housing of the dust collector includes a wall that defines an intake passage. The intake passage extends from the intake portion side to the filter side. One end of the intake passage is linked to the outside of the housing via the intake portion. Another end of the intake passage opposes a top surface side region of the intake side surface of the filter in a third direction perpendicular or substantially perpendicular to the first direction and the second direction. When viewed from the first direction, the top surface side region approaches the another end of the intake passage as it approaches the top surface side in the second direction.

A de-dusting unit positionable in a vacuum chamber of a vacuuming device, where the vacuum chamber is delimited by a turbine, a first filter, and a second filter. The de-dusting unit includes a displacement module where the de-dusting unit is positionable within the vacuum chamber by the displacement module such that one of the first and second filters at a time is isolated from a suction flow and such that an oscillating movement of the de-dusting unit is transmitted to the isolated filter.

In accordance with the present disclosure a modular air treatment system is disclosed. The modular air treatment system includes a fan apparatus having a base to removably couple to at least one of an air filter and/or a humidifier, wherein the fan apparatus includes a fan body with at least one convex surface and a nozzle to output air along the at least one convex surface.

An electric vacuum cleaning apparatus includes a station and an electric vacuum cleaner connectable/disconnectable from the station. The electric vacuum cleaner includes: a coarse-dust collecting chamber that accumulates coarse dust separated with a first separator; a filter chamber that accumulates fine dust separated with a filter; a coarse-dust waste-outlet that discharges the coarse dust from the coarse-dust collecting chamber; a fine-dust waste-outlet adjacent to the coarse-dust waste-outlet and discharges the fine dust from the filter chamber; and a waste-outlet lid that opens/closes both the coarse-dust waste-outlet and fine-dust waste-outlet together. The station includes: a secondary dust container accumulating coarse dust to be discharged from a primary dust container through the coarse-dust waste-outlet port and fine dust to be discharged from the primary dust container through the fine-dust waste-outlet; and a secondary electromotive blower that applies negative pressure to the primary dust container to transfer the coarse and fine dust.

Embodiments of the present disclosure provide a robot, a robot system, a dust box, and a control method. The robot includes a body, provided with a suction port and a dust box, which are fluid communicated. The dust box is provided with a plurality of dust outlets and a dust inlet communicated with the suction port. All of the plurality of dust outlets are closed when the body is in a first mode, and dust on a surface is collected into the dust box through the suction port. The plurality of dust outlets work cooperatively to discharge the dust stored in the dust box under an action of a suction airflow when the body is in a second mode. The amount of dust residue in the dust box may be effectively reduced according to the technical solution provided by the embodiments of the present disclosure.

A hand vacuum cleaner has a front end, a rear end, a longitudinal axis extending between the front and rear ends, an air flow passage, an air treatment member, an outer wiper, and a front door. The air treatment member includes a treatment chamber having a porous dirt separator. The wiper travels across at least a portion of an outer wall of the porous dirt separator as the wiper moves between a first position to a second position. The front door is moveably mounted between a closed position and an open position, and is drivingly connected to the wiper whereby when the front door moves from the closed position to the open position, the wiper travels from the first position to the second position. A hand vacuum cleaner also has a first cleaning stage which is rotatable to an open position wherein as the first cleaning stage is opened a wiper cleans a porous substrate.

A robotic cleaner may include a body, an agitator chamber within the body, an agitator disposed within the agitator chamber, a dust cup removably coupled to the body, the dust cup including a debris inlet, the debris inlet fluidly coupling the dust cup to the agitator chamber, and a shutter configured to transition between a cleaning position and an evacuation position in response to rotational movement of the agitator.

A cleaner includes a housing including a suction opening, a cyclone part configured to separate air and dust, and a dust bin configured to store dust separated from air in the cyclone part and a frame disposed to surround an axis of a cyclone flow of the cyclone part in the housing and configured to be movable between a first position and a second position in the housing, wherein the frame includes a first body disposed to face the suction opening at the first position and disposed to be inclined with respect to the axis of the cyclone flow, and an upper end of the first body is located to be the same as or higher than an upper end of the suction opening.
