Abstract: A vacuum cleaner includes a cleaner body, a connection pipe including a first catching groove, and a suction nozzle. The suction nozzle includes a connection neck, a nozzle housing rotatably coupled to the connection neck, a first catching body rotatably coupled to the connection neck, and a first elastic body. The first catching body includes a first catching protrusion portion which is caught by the first catching groove. The suction nozzle includes a pressing portion and a first lever. The first lever includes a first end portion in contact with the pressing portion, and a second end portion configured to press the first catching body. According to the disclosed vacuum cleaner, the fastening between the suction nozzle and the connection pipe may be maintained or released according to the relative angle between the suction nozzle and the connection pipe.

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 vacuum cleaner includes a connection pipe, a cleaner body, a suction nozzle having a first suction port, a movable body, a first rotating body, and a second rotating body. The movable body is movably coupled to the connection pipe, and the first rotating body and the second rotating body are rotatably coupled to the movable body. According to the disclosed vacuum cleaner, in a state in which the connection pipe is separated from the suction nozzle, the first rotating body and the second rotating body may form a second suction port, and may form a nozzle other than the suction nozzle.

Abstract: A vacuum cleaner is disclosed. The vacuum cleaner comprises a cleaner body, a suction nozzle, a connection pipe, a first tool assembly, a second tool assembly, and a pipe assembly. The first tool assembly is detachably fixed to a body suction port of the cleaner body and has a first suction port which communicates with the body suction port. The second tool assembly is detachably fixed to the first tool assembly and has a second suction port which communicates with the body suction port. The pipe assembly is fixed to the rear side of the connection pipe and detachably fixed to the second tool assembly. The first tool assembly, the second tool assembly, or the pipe assembly can be selectively detached from the cleaner body, and each tool (suction port) can be effectively used.
