Abstract
A vacuum cleaner for performing autonomous driving may include: a main body; a driving unit; a suctioning unit; a plurality of sensors for sensing obstacles present in each direction; and a control unit for controlling the driving unit to move the main body on the basis of a preset driving pattern. The control unit uses sensors provided at the front side of the main body and a first side of the both sides of the main body so as to detect whether entry into a corner area among cleaning areas is made while driving along the preset driving pattern, and controls the driving unit such that the first side of the main body comes into contact with a first wall forming the corner area at least one time when the main body enters the corner area.
