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 cyclonic separator having a first cyclone stage; and a second cyclone stage comprising a plurality of cyclone bodies arranged in parallel, each cyclone body comprising an inlet and an outlet, the plurality of cyclone bodies being divided into at least a first layer and a second layer; wherein the second cyclone stage further comprises a first plenum common to the cyclone bodies, the first plenum extending from the outlet of the first cyclone stage to the inlets of each of the cyclone bodies of the second cyclone stage.

A cyclonic separating device includes first and second cyclonic separating units. The first cyclonic separating unit is fitted over the second cyclonic separating unit. The second cyclonic separating unit includes first cyclones and second cyclones respectively arranged in a ring shape. Dust falling ends of the first cyclones define an accommodation space therebetween. The second cyclones partially extend into the accommodation space. Each first cyclone comprises first, second and third cone sections, each of which has a cone structure; airflow sucked in the first cyclones is sequentially separated by the first, second and third cone sections, and dust in the airflow is discharged from the third cone section; a central axis of the first cone section is parallel to a longitudinal axis of the dust cup; and an angle between a central axis of the second cone section and a central axis of the third cone section is 5°-20°.

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 cleaner includes: a suction motor that generates suction force; a dust separation unit that separates dust from air sucked by the suction force; a motor housing that covers the suction motor; a flow guide that surrounds an outer side of the motor housing and guides air discharged from the dust separation unit to the suction motor; and a body that forms an external appearance by surrounding the flow guide and guides air discharged from the suction motor together with the flow guide.

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.
