Disclosed is a robot cleaner which cleans a floor, and generates negative-ions while traveling around a predetermined area. The robot cleaner includes a cleaner body which travels automatically around a cleaning area, a driving unit for driving a plurality of wheels mounted on a lower part of the cleaner body, a suction unit mounted in the cleaner body to draw in dust on a floor, a negative-ion generation unit mounted in the cleaner body to generate a negative-ion, and a control unit. 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-ion, which enables a hygienic cleansing and a healthy home environment.
