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.
