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.
