    Abstract: A nozzle of a cleaner includes: a housing; a rotation cleaning unit accommodated in the housing and configured to clean a surface based on a rotation operation; and a drive unit inserted into a side of the rotation cleaning unit. The drive unit includes a motor, a motor supporter fixed to the housing and coupled to the motor, a gear unit connected with a rotation shaft of the motor to transfer a driving force, and a shaft connected to the gear unit and the rotation cleaning unit to transfer a rotation force to the rotation cleaning unit. The motor includes a printed circuit board (PCB) installation portion in which a PCB is installed and which is spaced apart from the motor supporter, in which a first space portion in which the air flows is formed between the motor supporter and the PCB installation portion.

    Abstract: A nozzle for a cleaner has a nozzle housing including a suction flow path configured to allow air and dust to flow therethrough. A water tank is mounted on the nozzle housing to store water. The nozzle also has first and second rotation cleaning units arranged on a lower side of the nozzle housing. Each of the first and second rotation cleaning units include a rotation plate coupled to a mop. The nozzle includes a first driving device that has a first driving motor to drive the first rotation cleaning unit. The nozzle also includes a second driving device that has a second driving motor to drive the second rotation cleaning unit. Further, the nozzle has a water discharge port provided at a bottom of the nozzle housing to supply water in the water tank to each of the first and second rotation cleaning units.
