Abstract: An air cleaner having a manipulator is disclosed. The manipulator (200) includes a rotary manipulation unit (300), which is provided so as to be movable between a first position, at which the rotary manipulation unit is retracted into the air cleaner, and a second position, to which the rotary manipulation unit is extracted from the air cleaner to enable a user to manipulate the rotary manipulation unit. The manipulator further includes a lift unit (400), which is installed in the air cleaner to move the rotary manipulation unit between the first position and the second position. In the present invention, the manipulator can control several functions of the air cleaner obviating the need for having several control buttons, thus being more convenient for a user. Furthermore, the present invention can prevent water from permeating a PCB mounted in the rotary manipulation unit, thus preventing malfunction of the encoder unit.
