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.

Abstract: A nozzle for a cleaner includes a nozzle housing including a suction flow path through which air including dust flows and at least a portion of which extends in a front and rear direction. First and second rotation cleaning units are arranged on the lower side of the nozzle housing to be spaced apart from each other in a lateral direction. Each of the first and second rotation cleaning units includes a rotation plate adapted for attachment of a mop. A first driving device including a first driving motor drives the first rotation cleaning unit and a second driving device including a second driving motor drives the second rotation cleaning unit. A water tank mounted on the nozzle stores water to be supplied to the mop.
