Abstract

A vacuum cleaner includes a body having a space that allows air to flow therethrough. The vacuum cleaner also includes a suction inlet configured to introduce the air into the body. Further, the vacuum cleaner includes a suction motor provided in the body. The vacuum cleaner includes a dust separation module provided in the body. The dust separation module is arranged between the suction inlet and the suction motor. The dust separation module separates foreign substances from the air. The vacuum cleaner includes an exhaust module that discharges the air passing through the suction motor from the body. The exhaust module includes an exhaust filter comprising a photocatalyst. Further, the vacuum cleaner includes a lighting module that radiates light toward the exhaust filter. The vacuum cleaner includes a battery supplying electrical energy for the operation of the vacuum cleaner and a controller configured that controls operations of the vacuum cleaner.
