Cleaner

A cleaner comprising:

• a main body configured to separate dust from air suctioned through an opening;
• a suction motor provided in the main body to generate a suction force;
• and
• a suction inlet including a connection pipe coupled to the opening to guide air to the main body,
• wherein the main body includes a suction guide protruded from the main body and coupled to one side of the connection pipe to guide air suctioned through the connection pipe to an inner circumferential surface of the main body,
• wherein the connection pipe includes a guide pipe having a longitudinal axis extended in a horizontal direction and a guide duct on which a rotatable flap is installed and extended from the guide pipe in the horizontal direction,
• wherein an end of the suction guide is in contact with the guide duct in a state in which the connection pipe is connected to the main body,
• wherein the guide duct includes:
• a first surface on which the flap is installed, and
• a second surface facing the first surface,
• wherein 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,
• wherein the first extension line is parallel to the one surface of the suction guide,
• wherein a third extension line of the flap and the first extension line form a second angle,
• wherein the second angle is equal to or smaller than the first angle, and
• wherein the longitudinal axis of the guide pipe passes through the flap.
