    Abstract: A cleaning apparatus includes a vacuum cleaner, a stand, a first coupling portion, a plurality of suction units, and an extension holder. The vacuum cleaner includes a main body configured to receive and discharge air. The vacuum cleaner is mounted in the stand. The first coupling portion is formed in the stand and is positioned behind the vacuum cleaner. One of the suction units is selectively coupled to an air inlet through which air is suctioned into the main body. A first connector coupled to the first coupling portion is located at one end of each of the suction units. The extension holder includes a second connector and second coupling portions. The second connector is coupled to the first coupling portion. The second coupling portions are respectively positioned on either side of the second connector.

    Abstract: A vacuum cleaner includes a main body and a suction nozzle that suctions up dust on the floor. The suction nozzle includes a housing, a driver, and a rotating brush. The housing includes an entrance through which the dust travels to the main body, a first shaft member, and a first rib disposed along a circumference of the first shaft member. The rotating brush includes a cylindrical body rotated by the first shaft member. The rotating brush also includes a brush member attached to an outer surface of the cylindrical body. The brush member rubs against the floor to direct the dust on the floor towards the entrance. As the brush member rotates, it also comes into contact with the first rib. The brush member includes a plurality of filaments. Some of the filaments are elastically deformed in the direction of the rotation axis upon contacting the first rib.

    Abstract: The cleaner includes a main body having an opening, a suction motor accommodated in the main body and configured to generate suction force, an opening cover separably coupled to the main body and configured to cover the opening, and a filter mechanism accommodated in the main body through the opening and configured to filter foreign substances of air discharged by the suction motor. When the opening cover is separated from the main body, at least a portion of the filter mechanism protrudes to the outside of the main body through the opening. While the opening cover is coupled to the main body, at least a portion of the filter mechanism protruding to the outside of the main body is pressed by the opening cover so as to be accommodated in the main body.

    Abstract: A vacuum cleaner includes a main body and a suction nozzle. The suction nozzle includes a connector that defines a passage configured to guide the dust in a first direction to the main body, and a housing that rotatably connects to the connector and defines an inlet configured to transfer the dust to the passage. The connector includes an insertion portion that has a cylindrical shape and is configured to insert into the inlet, a first connection portion spaced apart from the inlet in the first direction, and a coupling part disposed at an outer surface of the insertion portion. The coupling part and the first connection portion are configured to restrict movement of the housing in the first direction, and the inlet is configured to restrict deformation of at least one of the insertion portion or the coupling part.

    Abstract: A cleaner includes: a main body for separating dust from air suctioned through an opening; a suction motor generating suction force; and a suction part coupled to the opening part and having a connection pipe for guiding the air to the main body. The main body includes a suction guide coupled to one side of the connection pipe including a guide duct having a rotatable flap provided thereto. The suction guide is connected to the guide duct. A suction duct includes: a first surface, where the flap is installed; and a second surface facing the first surface. A second extension line of the second surface forms a first angle with a first extension line of one surface, of the suction guide, connected to the second surface. The first extension line and a third extension line of the flap form a second angle equivalent to or smaller than the first angle.
