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: A cleaner is disclosed. The cleaner includes: a housing having an introduction opening through which air is introduced; a filtering unit configured to be mounted in an inner space of the housing, and defining a dust collection space between the filtering unit and an inner surface of the housing; and a cleaning unit surrounding the filtering unit and configured to be raised and lowered. When the cleaning unit is in an initial position at least a portion of the cleaning unit is connected to an air introduction path extending from the introduction opening such that the cleaning unit guides a flow of introduced air. A guide edge extends from a lower portion of the cleaning unit toward a bottom of the dust collection space, and a surface of the guide edge facing the inner surface of the housing is inclined.
