Abstract: A cleaner is disclosed, which comprises a main body including an suction inlet through which air containing dust enters, a dust separator provided to separate dust from the air while the air entering from the suction inlet is moving, a first dust collector configured to collect the dust separated by the dust separator, a cyclone portion configured to rotate the air to separate the dust from the air, and a second dust collector collecting the dust separated by the cyclone portion. The dust separator is provided with a plurality of plate shaped members arranged at a predetermined angle with respect to a moving direction of the air, and arranged to be spaced apart from one another to move the air.

Abstract: A dust cleaner includes a primary cyclone part formed by an outer case and an inner case; and a secondary cyclone part including a set of cyclones. The secondary cyclone part includes a casing member mounted on the inner case and configured to form casings of the cyclones arranged around a hollow part; and vortex finders provided inside the casings and including guide vanes extending in a spiral direction and forming a revolving flow at outer circumferential surfaces. The casing member forms inlet flow paths of the cyclones, and each of the inlet flow paths is formed in a direction inclined with respect to a direction toward a center of each of the vortex finders to enable air to flow in a direction eccentric from the center of each of the vortex finders.
