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.

A docking station for a robotic surface cleaning apparatus has a momentum separator. The momentum separator has a plurality of walls comprising an upper wall, a lower wall and a first sidewall, wherein the first sidewall extends between the upper and lower walls, and wherein the first sidewall comprises a side screen. A first end wall is spaced from and faces the side screen wherein an up flow chamber is positioned between the first end wall and the side screen.

A docking station for a robotic surface cleaning apparatus has a momentum separator. The momentum separator has an upper wall, a lower wall and a first sidewall extending between the upper and lower walls. The first sidewall comprises a side screen and an end wall is spaced from and faces the side screen whereby an up flow chamber is positioned between the end wall and the side screen. The upper wall also comprises an upper screen and an upper end wall is spaced from and faces the upper screen wherein an upper air flow chamber is positioned between the upper end wall and the upper screen.

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.

A hand vacuum cleaner comprises a cyclone comprising a front end having a cyclone air inlet, a rear end having a cyclone air outlet and a cyclone axis of rotation extending between the front end and the rear end of the cyclone. A conical pre-motor filter is positioned rearward of the cyclone. The pre-motor filter has a front end that faces that faces towards the cyclone air outlet. A suction motor is positioned rearward of the pre-motor filter. The suction motor has an inlet end that faces towards a rear end of the pre-motor filter. A handle is provided at the rear end of the hand vacuum cleaner and is positioned rearward of the suction motor. The handle has an energy storage member housing, The cyclone axis of rotation and the suction motor axis of rotation are parallel, and the handle axis extends at an angle to the cyclone axis of rotation and the suction motor axis of rotation.

A dust accumulation base and a cleaning apparatus assembly having same are disclosed. The dust accumulation base includes: a dust collection part, the dust collection part being internally provided with a dust collection chamber used for collecting dust in a cleaning apparatus, and the dust accumulation base being provided with a dust inlet communicated with the dust collection chamber; and a support part, the support part being used for supporting the cleaning apparatus, and the support part being provided with an avoidance area capable of accommodating or avoiding an air suction accessory of the cleaning apparatus.

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.

An evacuation station for collecting debris from a cleaning robot includes a controller configured to execute instructions to perform one or more operations. The one or more operations includes initiating an evacuation operation such that an air mover draws air containing debris from the cleaning robot, through an intake of the evacuation station, and through a canister of the evacuation station and such that a receptacle received by the evacuation station receives at least a portion of the debris drawn from the cleaning robot. The one or more operations includes ceasing the evacuation operation in response to a pressure value being within a range. The pressure value is determined based at least in part on data indicative of an air pressure, and the range is set based at least in part on a number of evacuation operations initiated before the evacuation operation.
