    Abstract: A vacuum cleaner includes a body having a space that allows air to flow therethrough. The vacuum cleaner includes a suction inlet that introduces the air into the body and a first cyclone in the body. The first cyclone separates foreign substances from the air introduced into the suction inlet. The vacuum cleaner includes a dust separation module having a filter unit that separates foreign substances from the air introduced from the first cyclone. The dust separation module also includes a second cyclone arranged within and separated from the filter unit. The second cyclone includes a cyclone base, a storage unit arranged adjacent to a lower portion of the second cyclone, and a cyclone array coupled to the cyclone base. The cyclone array allows the air to pass through an upper portion of the second cyclone and discharge the foreign substances collected by the second cyclone to the storage unit.

    Abstract: 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.
