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.
