Abstract
A dust separator of a cyclone type cleaner includes a first dust separator connected to a suction pipe, for separating dust from air by a centrifugal force for the first time; a collecting container connected to a lower portion of the first dust separator and in which the dust separated in the first dust separator is collected; and a second dust separator connected to an upper portion of the first dust separator, for sucking air which has passed through the dust separation in the first dust separator and separating dust from the air by a centrifugal force for the second time, so that an efficiency of collecting dust is improved without deteriorating a suction force of air.
