Abstract: A vacuum cleaner is disclosed. The vacuum cleaner comprises: a suction nozzle including a rotating cleaner located in front of a suction port; a cleaning main body provided with a first motor that generates a suction force; and a distance sensor coupled to the suction nozzle. The distance sensor detects a distance from a wall surface located in front of the suction nozzle, and when the distance (distance value) is less than or equal to a reference value, the rotation speed of the first motor is increased. Accordingly, when the suction nozzle touches the wall surface and cannot move forward, the suction force is momentarily increased such that foreign substances such as dust can be effectively sucked in from the edge of the wall surface, and effective use of a battery can be achieved.
