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.

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.
