    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 nozzle for a cleaner includes a nozzle housing that has a suction flow path that allows air containing dust to flow therethrough. The nozzle also includes a driving device including a driving motor. Further the nozzle includes a rotation cleaning unit including a rotation plate which is connected to the driving device at a lower side of the nozzle housing. The nozzle also includes a mop attached to a lower side of the rotation plate. In addition, the nozzle includes a water tank mounted on an upper side of the nozzle housing and configured to store water. The water tank is separable from the nozzle housing. An upper side wall of the water tank forms an upper surface of the nozzle when the water tank is mounted on the nozzle housing, and a portion of a bottom wall of the water tank is configured to surround the driving device.
