PURPOSE: A multiple cyclone dust collecting device is provided to enhance a dust collecting property of a foreign material by allowing an outer surface of a second cyclone body to guide rotation of air, and increasing a centrifugal force. CONSTITUTION: A multiple cyclone dust collecting device is composed of a first cyclone body(110) and a first dust collecting portion(120) for collecting primarily a foreign material, a second cyclone body(130) and a second dust collecting portion(140) for collecting secondly a foreign material, an air discharging pipe(160), and a suction force generating device. The first cyclone body is formed in a cylindrical shape, an intake port is provided at one side of an outer circumference surface, and a discharging port is provided at the other side thereof. An air intake pipe(150) is installed at the intake port, and the discharging port is communicated with the first dust collecting portion through a first connecting pipe(181).
