PURPOSE: A cyclone dust collecting device is provided to enhance a dust collecting efficiency of a second dust collecting device by improving a structure of the cyclone dust collecting device. CONSTITUTION: A cyclone dust collector is composed of a first dust collector(10) having an inertial collecting body(11) for collecting primarily a dust or waste using an inertial force, and a second dust collector(20) having a cyclone body(21) for performing a collecting of the dust or waste using a centrifugal force. A central portion of the cyclone body(21b) is expanded outward, and communicates with the inertial collecting body. Therefore, a part of a waste introduced into the cyclone body is collected from the central portion of the cyclone body to the inertial collecting body primarily.
