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: 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.
