    Abstract: A dust collector includes a primary cyclone unit to separate dust from air introduced from outside dust collector and a secondary cyclone unit includes axial cyclones which separate fine dust from air introduced in an axial direction. The secondary cyclone unit includes a first group of axial cyclones disposed along a circumference of a first circle so as to contact an inner circumferential surface of an inner case, and formed to be partially spaced apart from the inner circumferential surface of the inner case to form first passages therebetween; and a second group of axial cyclones disposed to contact each other along a circumference of a second circle concentric with the first circle and smaller than the first circle, and formed to contact some of the first group of axial cyclones and to be spaced apart from others of the first group axial cyclones to form second passages therebetween.

    Abstract: The present disclosure relates to a cleaner capable of easily separating a filter module from a main body of the cleaner and separating and assembling the separated filter module again. Disclosed is a cleaner including: a main body; a suction motor disposed in the main body and configured to generate a suction force so as to suction air; a dust separator separating dust from air by generating a cyclone flow in air introduced by the suction motor; and a filter module having a filter for filtering air discharged from the suction motor and being detachable from the main body. Here, the filter module is configured to be easily separated from the main body of the cleaner and assembled, such that the filter disposed inside the filter module may be easily cleaned or replaced.
