Abstract: 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.

Abstract: A cleaner includes a nozzle assembly, a cleaner body in communication with the nozzle assembly, and a damp cloth-based wiping unit coupled to the nozzle assembly. The damp cloth-based wiping unit includes a water tank. The water tank includes a storage space defined therein for storing water, an air hole defined in a top face of the water tank for receiving external air, a discharging port formed on a bottom face of the water tank for discharging the water from the storage space, and a deformable member configured to be depressed inwardly into the storage space. A damp cloth is attached to a bottom face of the water tank for receiving the water discharged through the discharging port. A pressing mechanism is configured to selectively press and translate the deformable member.

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.
