The water tank includes a first chamber, and a second chamber spaced apart from the first chamber in the left-right direction of the nozzle housing.

A nozzle for a cleaner has a nozzle housing including a nozzle base and a nozzle cover coupled to an upper side of nozzle base, the nozzle cover including a bottom wall recessed towards the nozzle base, a flow path forming portion positioned between the nozzle base and the nozzle cover, a connection tube positioned at a rear side of nozzle housing, a water tank positioned on the nozzle cover and a plurality of rotation cleaning units arranged on a bottom side of the nozzle base and spaced apart from each other in a lateral direction, each the plurality of rotation cleaning units including a rotation plate configured to be coupled to a mop.

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.

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.

A nozzle for a cleaner includes a nozzle body having a suction passage in which air flows. A water tank is detachably mounted on the nozzle body, and a rotation cleaning part is rotatably supported at a lower side of the nozzle body to receive water from the water tank for cleaning a floor. The water tank includes an outlet through which water is discharged, a valve configured to open and close the outlet, and an air hole configured to introduce outside air into the water tank. An air hole operation part is movably installed on the water tank to open and close the air hole.

A traveling floor cleaning machine is provided, including a chassis, a cleaning tool apparatus which is arranged on the chassis with at least one cleaning tool and a holder for the at least one cleaning tool, and a suction apparatus which includes a suction unit and an aspiration apparatus, wherein the suction unit is arranged on the holder.

The present disclosure relates to a nozzle of a cleaner. The nozzle of a cleaner includes: a nozzle main body having a suction flow path through which air is suctioned; a first rotation cleaning unit and a second rotation cleaning unit spaced apart in a left and right direction on a lower side of the nozzle main body and including a rotation plate to which mop is attachable; a first driving device disposed on one side of a flow path extending in a front and rear direction in the suction path and including a first driving motor for driving the first rotation cleaning unit; a second driving device disposed on the other side of the flow path extending in the front and rear direction in the suction path and including a second driving motor for driving the second rotation cleaning unit.
