ABSTRACT:
Disclosed is a cyclone separating apparatus, and a vacuum cleaner having the same. The cyclone separating apparatus includes a first cyclone separating dust from dust-ladened air. A plurality of second cyclones centrifugally separate fine dust particles from air which is first separated at the first cyclone. A dust collecting unit detachably connects to the first and the second cyclones. The dust collecting unit separately collects large dust particles separated at the first cyclone, and fine dust particles separated at the second cyclone. Accordingly, a more compact cyclone separating apparatus can be realized with improved suction efficiency and dust collecting efficiency.
