A robot cleaner which cleans a floor, and generates negative ions while traveling around a predetermined area. The robot cleaner includes a cleaner body 12 which travels automatically around a cleaning area, a driving unit (20, Fig 3) for driving a plurality of wheels (21 and 22, Fig 4) mounted on a lower part of the cleaner body, a suction unit (16, Fig 4) mounted in the cleaner body to draw in dust on a floor, a negative-ion generation unit 11 mounted in the cleaner body to generate negative ions, and a control unit (10, Fig 4). While the robot cleaner travels automatically, it also performs vacuum cleaning using the suction unit, and air cleaning using the negative-ion generation unit, either at the same time or selectively. Accordingly, the floor is cleaned and air is purified by the negative ions, which enables hygienic cleansing and a healthy home environment.
