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.

Abstract: Disclosed is a vacuum cleaner. The vacuum cleaner according to the present disclosure includes a main body and a suction nozzle. The suction nozzle includes a housing and a rotating brush. The rotating brush includes a first rotating brush, a second rotating brush, and a coupler. The coupler couples the first rotating brush and the second rotating brush so that a rotation axis of the first rotating brush and a rotation axis of the second rotating brush are positioned on the same line.
