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.
