A bag-based filtering device for collecting debris from a cleaning robot via a debris evacuation station includes a filter bag configured to separate at least the portion of the evacuated debris from a flow of air generated by the evacuation station. The filtering device includes a conduit extending inward from an opening of the filter bag into the receptacle. The conduit is configured to pneumatically connect a receptacle of the filtering device with an inlet of the filtering device to direct the flow of air generated by the evacuation station through the filter bag to separate at least the portion of the evacuated debris from the flow of air.

A hand vacuum cleaner has a cyclone assembly having a cyclone with a central longitudinally extending axis wherein, when the upper end of the hand vacuum cleaner is positioned above the lower end of the hand vacuum cleaner, the central longitudinally extending axis is oriented generally horizontal. The cyclone assembly has a cyclone assembly height that extends between an upper end of the cyclone assembly and a lower end of the cyclone assembly with a medial portion of the cyclone assembly positioned between the upper end and the lower end of the cyclone assembly. A housing containing the suction motor is positioned rearward of the cyclone assembly and extends downwardly from the upper end of the cyclone assembly to the medial portion. A pistol grip handle is positioned rearward of the cyclone assembly, below the housing and extends downwardly from the medial portion.

A robot cleaner is provided. The robot cleaner includes a main body including a suction device configured to intake dust and a dust container detachably mounted on the main body and configured to separate and store dust from air intaken by the suction device, wherein the dust container includes a first chamber configured to separate and store dust from air introduced from the suction device, a second chamber configured to separate and store dust from air introduced from the first chamber, a dust collecting cover configured to filter dust in air introduced from the first chamber into the second chamber, and an airflow guide disposed on an upper portion of the dust collecting cover and configured to guide air flowing above the upper portion of the dust collecting cover toward the second chamber.

A vacuum collection vehicle may include a chassis, a vacuum container supported by the chassis, a vacuum source in pneumatic connection with an interior of the vacuum container. A plurality of discharge conduits have a plurality of respective outlets at different locations within the interior of the vacuum container for discharging collected material into different collection receptacles. Inner collection receptacle supports support transmissive flexible and collapsible inner collection receptacles below the outlets. Outer collection receptacle supports support non-transmissive flexible and collapsible outer collection receptacles about and spaced from the transmissive flexible and collapsible inner collection receptacles.

An evacuation station for a surface cleaning apparatus comprises a stationary base portion and an removable portion comprising an air treatment assembly that is moveably mounted to the stationary base portion. A pre-motor filter is exposed when the removably portion is removed from the stationary portion.

A docking station, which includes a cover opening and closing device for automatically opening and closing a dust container cover, and a cleaning device is provided. The cleaning device includes a cleaner which includes a dust container for collecting foreign substances, a dust container cover rotatably coupled to the dust container so as to open and close the dust container, and a button provided to open the dust container, a docking station to which the cleaner is coupled, and which charges the cleaner coupled thereto, and a cover opening and closing device which opens the dust container cover by pressing the button and closes the dust container cover by pressing the dust container cover.

A cleaner includes: a suction unit; a suction motor that generates suction force for sucking air through the suction unit and includes an impeller; a dust separation unit that includes one or more cyclone units generating cyclonic flow to separate dust from air flowing inside through the suction unit; a dust container that stores dust separated by the dust separation unit and is disposed under the suction motor; a battery disposed behind the dust container to supply power to the suction motor; and a handle disposed behind the suction motor, wherein a rotational axis of the impeller and an axis of the cyclonic flow vertically extend and an extension line from the rotational axis of the impeller passes through the one or more cyclone units.

An operating method of a station device for discharging dust from a cordless vacuum cleaner includes detecting occurrence of an event requesting discharging dust from a dustbin included in the cordless vacuum cleaner to the station device, and performing a dust discharge operation for discharging dust in the dustbin to a collector of the station device based on detecting of the occurrence of the event. The performing a dust discharge operation includes transmitting, to the cordless vacuum cleaner via short-range wireless communication, a control signal for operating a first suction motor of the cordless vacuum cleaner, and operating a second suction motor of the station device in cooperation with the first suction motor.

An evacuation station for a mobile floor cleaning robot comprises a housing having a perimeter extending around the housing and an air treatment assembly. The air treatment assembly is moveable from an in use position in which the air treatment assembly is mounted to the housing and a removal positon in which all of the air treatment assembly is positioned outwardly of the perimeter.

A vacuum collection vehicle may include a chassis, a vacuum container, a filter unit, a first discharge conduit and a second discharge conduit. The filter unit may include a filter housing that supports a filter independent of opposing interior walls. The vehicle may include a storage container supported by the chassis and containing a vacuum source or hose reel. The vehicle may include inner and outer collection receptacle supports for supporting collection receptacles within the vacuum container.
