PURPOSE: A dust collector for the vacuum cleaner employs a cyclone to keep the regular suction force for collecting dust in the regular direction. CONSTITUTION: The dust collector has two extension tube sections, one connecting to a main body having a suction force generator in it and the other connecting to a hand grip and to a suction mouth. The air and dust in suction flow smoothly through the tube and cyclone in the regular direction of suction and discharge to the effect of better dust collection.
