A debris removal assembly of the vacuum cleaner can include a filter assembly having a first filter and a second filter arranged in a nested configuration, and a filter cleaning mechanism configured to impart a combination of vertical shaking of the first filter and rotational flicking of the second filter. The filter cleaning mechanism can include a camming mechanism configured to simultaneously move the first filter along the axis and rotate the first filter about the axis while the second filter remains stationary

A vacuum collection vehicle may include a chassis, a vacuum container supported by the chassis, a vacuum source separated from the vacuum container by an intermediate wall and a filter. The vacuum source is in pneumatic connection with the filter through the intermediate wall. A plurality of discharge conduits extend through the intermediate wall, extend over and above the filter, along the roof of the vacuum container. The 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. The filter is sandwiched between the intermediate wall and the plurality of discharge conduits.

The disclosure provides a debris bin assembly, a cleaning robot and a cleaning robot system, the debris bin assembly includes a debris bin housing, a filter assembly, and a flow guide plate, the debris bin housing includes a top portion and a bottom portion disposed opposite to the top portion, and a side housing surrounding the top portion and the bottom portion, the top portion, the bottom portion and the side housing are enclosed to form an inner cavity, the top portion of the debris bin housing is provided with an air exhaust channel communicating with the inner cavity and an air outlet communicating with the air exhaust channel, the side housing is provided with an air inlet communicating with the inner cavity, the air inlet inclines towards a side where the top portion is located, the filter assembly is disposed in the air exhaust channel of the top portion, the flow guide plate is located in the inner cavity and is disposed opposite to the air inlet, the flow guide plate extends from the top portion to the bottom portion and is configured for intercepting, decelerating and laterally guiding air flow entering from the air inlet, so as to decelerate and laterally guide air flow carrying debris, which avoids debris directly impacting a filter screen at a high speed and attaching to it, and consequently, a problem that the filter screen is easily blocked is solved.

A portable surface cleaning apparatus has a main body and air treatment member assembly is removably mounted to the main body. The air treatment member assembly air outlet and/or the suction motor inlet end is provided at the lower end of the air treatment member assembly when the surface cleaning apparatus is located on a floor and a pre-motor filter underlies the air treatment member assembly and/or the suction motor.

A docking station for a mobile cleaning robot can include a base and a canister. The base can be configured to receive at least a portion of the mobile cleaning robot thereon. The base can include an electrical power interface configured to provide electrical power to the mobile cleaning robot. The canister can be connected to the base and can be located at least partially above the base. The canister can include a debris bin to receive debris from the mobile cleaning robot.

A method for emptying cleaning robots and cleaning system, having a dirt collection unit and a suction interface using a trolley, configured to store the plurality of cleaning robots outside their cleaning phase in which they carry out cleaning tasks, and which has a suction system with a foldable suction platform, a suction opening, a dirt container, and a blower. The method includes the steps of unfolding the suction platform of the trolley, if it is folded, so that it is arranged on a substrate on which the trolley stands in an operational set-up position, arranging one of the cleaning robots on the unfolded suction platform, aligning the suction interface to the suction opening, and activating the blower in order to empty the cleaning robot arranged and aligned on the suction platform so that dirt is transported from the dirt collection unit into the dirt container.

A cleaner comprises a housing having a dust collection chamber formed in the housing and configured to open and close, a main body movable relative to the housing between a first position whereby the main body closes the dust collection chamber and a second position whereby the main body opens the dust collection chamber, and a motor filter mountable to and demountable from the main body, wherein the main body includes a fan motor unit to generate a suction force, and a shutter device mountable into the main body and configured to open and close a flow path between the motor filter and the fan motor unit.

A docking station for a robotic vacuum cleaner has a pneumatic transfer mechanism that is used to direct air to the robotic vacuum cleaner to thereby transfer dirt from the robotic vacuum cleaner to a docking station.

A suction device (10) with a suction device housing (20), in which a suction turbine (11) for generating a suction flow (S) is arranged, the suction turbine (11) having a suction turbine inflow opening (11A), through which the suction flow (S) can flow into the suction turbine (11) and at least one suction turbine outflow opening (11B), through which the suction flow (S) can flow out of the suction turbine (11), wherein the suction device housing (20) has a suction inlet (12) for letting in the suction flow (S) and a dust collecting chamber (21) for collecting dust contained in the suction flow (S), wherein a filter element (13) for retaining dust in the dust collecting chamber (21) is arranged between the dust collecting chamber (21) and a suction turbine inflow opening (11A) of the suction turbine (11), wherein the suction device (10) has a closure element (60) with a closure body (61) for closing the suction inlet (12), which closes the suction inlet (12) in a closure position (V) and is removed from the suction inlet (12) in a release position (FS). The suction device (10) has a supply receptacle (68) for receiving the closure body (61), when the closure body (61) reaches the release position (FS).
