A robot cleaner comprising: a cleaner body including a controller, the cleaner body having a dust container accommodation part formed therein; a wheel unit mounted in the cleaner body, the wheel unit of which driving is controlled by the controller; and a dust container detachably coupled to the dust container accommodation part, wherein a first opening and a second opening are disposed at the same height in an inner wall of the dust container accommodation part, wherein the dust container includes: an entrance and an exit, disposed side by side along the circumference of the dust container, the entrance and the exit, respectively communicating with the first opening and the second opening when the dust container is accommodated in the dust container accommodation part; and a flow separating part extending downwardly inclined along the inner circumference of the dust container.

A cyclonic separating apparatus comprising a first cyclonic separating unit and, downstream from the first cyclonic separating unit, a second cyclonic separating unit comprising a plurality of cyclones arranged fluidly in parallel about a first axis and a dust collector arranged to receive dust from each of the plurality of cyclones. Each of the plurality of cyclones in the second cyclonic separation unit comprise a fluid inlet and a fluid outlet, the plurality of cyclones being divided into at least a first set of cyclones and a second set of cyclones, the fluid inlets of the first set of cyclones arranged in a first group and the fluid inlets of the second set of cyclones arranged in a second group spaced along said axis from the first group. Each outlet of the plurality of cyclones in the second cyclonic separation unit is provided by a common plate-like vortex finder member.

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 hand vacuum cleaner has an air treatment member positioned in the air flow path downstream of a dirty air inlet. A motor and fan assembly produces an air flow through the air flow path. A handle is moveable between a first use position and a second use position.

A cleaner includes a dust bin, a motor housing disposed above and coupled to the dust bin, a handle coupled to the motor housing, a cyclone part disposed in the dust bin and configured to separate dust from air, a filter disposed in the dust bin and configured to filter air having separated the dust through the cyclone part, and a compression part configured to compress the dust in the dust bin. The compression part includes an operating part disposed in the motor housing and configured to move in a space between an outer portion of the filter part and an inner circumferential surface of the dust bin, a manipulation part disposed outside the motor housing and configured to be manipulated to move the operating part, and a transmission part that is disposed in the motor housing and connects the operating part and the manipulation part.

A hand vacuum cleaner has a cyclonic stage which comprises a stationary portion and an openable portion. The openable portion is rotatably mounted by a rotatable mount between a closed position in which a cyclone chamber is closed and an open position in which the cyclone chamber is open. The stationary portion comprises an upper portion of the first cyclonic stage and the openable portion comprises a lower portion of the first cyclonic stage. The rotatable mount is located at a rearward end of the openable portion.

A hand vacuum cleaner has an upper end, a lower end, an air flow passage, a main body with a handle, an air treatment chamber and a suction motor. The air treatment chamber has an air outlet, the air outlet comprising a rigid porous member and a filter media that is removably positionable in the rigid porous member. The air treatment chamber is moveable to an open position in which the air treatment chamber is emptyable, and the rigid porous member is moveable within the air treatment chamber to an open position in which the filter media is removable.

A hand vacuum cleaner has a cyclonic stage which comprises a stationary portion and an openable portion. The openable portion is rotatably mounted by a rotatable mount between a closed position in which a cyclone chamber is closed and an open position in which the cyclone chamber is open. The stationary portion comprises an upper portion of the first cyclonic stage and the openable portion comprises a lower portion of the first cyclonic stage. The rotatable mount is located at a rearward end of the openable portion.

Provided is a dust collector of a vacuum cleaner, the dust collector including a dust collecting casing including an air inlet, an air outlet, and a foreign substance discharge port, a cyclone module configured to separate foreign substances by inducing a swirling flow of air drawn in via the air inlet, and a discharge door switchable between an open position in which the foreign substance discharge port is opened and a closed position in which the foreign substance discharge port is closed, wherein the cyclone module includes a fixed part and a rotating part having a rotating state in which it is allowed to rotate with respect to the fixed part when the discharge door is in the open position and a locked state in which it is prevented from rotating with respect to the fixed part when the discharge door is in the closed position.

A vacuum cleaner has a portable cleaning unit that is removably mounted to the surface cleaning head. The vacuum cleaner is operable in a floor cleaning configuration in which the portable cleaning unit is mounted to the surface cleaning head and is part of the air flow path through the vacuum cleaner. The portable cleaning unit is also useable in a portable cleaning configuration in which the portable cleaning unit is removed from the surface cleaning head and the suction motor is powered by an energy storage member.
