Abstract
Abstract A cyclone separating apparatus and a vacuum cleaner having the same are disclosed. More specifically, the cyclone separating apparatus for a vacuum cleaner comprises a first cyclone for separating drawn-in air, and a plurality of second cyclones installed on an outer periphery of the first cyclone to enclose the first cyclone. Accordingly, because a plurality of the cyclones separates dust, and a bulky structure is improved to a compact structure, suction force deterioration does not occur, and, dust-collecting efficiency is increased.
