ABSTRACT:
An automatic charging device and method of an automatically traveling cleaner are disclosed. Since a charging terminal unit is installed inside a traveling cleaner and selectively drawn out, the traveling cleaner is prevented from being damaged from collision with an object while being moved forwardly. In addition, because a power source terminal, a contact sensor unit and a charging terminal unit are formed in a shape of a circular arc, the entering angle of the traveling cleaner widens, so that the charging induction time can be much reduced and the charging can be performed easily and quickly.
