PURPOSE: An automatic cleaner is provided to automatically perform a cleaning process without supplying the power to the automatic cleaner by increasing the rotational force of a wheel of the automatic cleaner. CONSTITUTION: A wheel attached to an automatic cleaner is rotated when a user moves the automatic cleaner by handling a handle(10). When the wheel of the automatic cleaner rotates, the first gear(1) connected to the wheel is rotated. The rotational force of the first gear(1) is transferred to the fifth gear(5) through the second gear(2), the third gear(3) and the fourth gear(4), so that a rotating brush(6) connected to the fifth gear(5) rotates. Waste collected by the rotating brush(6) is stored in a waste container(8). If waste collected in the waste container(8) reaches a predetermined level, a user empties the waste container(8).
