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 cleaning apparatus includes a vacuum cleaner, a stand, a first coupling portion, a plurality of suction units, and an extension holder. The vacuum cleaner includes a main body configured to receive and discharge air. The vacuum cleaner is mounted in the stand. The first coupling portion is formed in the stand and is positioned behind the vacuum cleaner. One of the suction units is selectively coupled to an air inlet through which air is suctioned into the main body. A first connector coupled to the first coupling portion is located at one end of each of the suction units. The extension holder includes a second connector and second coupling portions. The second connector is coupled to the first coupling portion. The second coupling portions are respectively positioned on either side of the second connector.
