    Abstract: A nozzle for a cleaner has a nozzle main body including an intake channel to suction air. The nozzle includes first and second rotary cleaning units spaced apart from each other in a lateral direction under the nozzle main body. Each of the first and second rotary cleaning units includes a rotary plate coupled to a dust cloth. The nozzle further includes a first driving device to drive the first rotary cleaning unit and a second driving device to drive the second rotary cleaning unit. The nozzle includes a water tank to store water. Further, the nozzle has a water supply channel to supply water in the water tank to the rotary cleaning units. The nozzle has a water pump and a pump motor to drive the water pump to pump the water to the dust cloth.

    Abstract: A nozzle for a cleaner according to an aspect of the present invention comprises: a housing; and a rotation cleaning portion rotatably coupled to the housing and having a body part and a brush part which is coupled to the outer peripheral side of the body part. The brush part comprises: a first brush coupled to the outer peripheral side of the body part and extending in the radial direction of the body part; and a second brush disposed alongside the first brush. The first brush is disposed so as to come in contact with a floor surface prior to the second brush during the rotation of the rotation cleaning portion, and is less stiff than the first brush.

    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.
