A cyclone dust collecting apparatus for a vacuum cleaner for easy removal of contaminants from a grill assembly. The cyclone dust collecting apparatus has a cyclone body that has a first connection pipe connected to an extension pipe adjacent to a suction port of the vacuum cleaner, a second connection pipe connected to the extension pipe adjacent to a body of the vacuum cleaner and, an air inflow port interconnected with the first connection pipe. An air outflow port is interconnected with the second connection pipe. The cyclone body is adapted to form an air flow vortex of contaminant-laden air that is drawn in through the air inflow port. A dust receptacle is removably connected to the cyclone body for receiving contaminants separated from the air by the vortex. A grill assembly is disposed at the air outflow port of the cyclone body, and has a plurality of longitudinal slots formed in an outer circumference of the grill body at a constant interval from each other to form a passage leading air toward the air outflow port. The grill assembly prevents a reverse flow of the contaminants collected in the dust receptacle through the air outflow port of the cyclone body. A contaminant removing member is movable upwardly and downwardly along the outer circumference surface of the grill body to remove contaminants that are attached to and around the respective longitudinal slots of the grill assembly. An operation lever has one end connected to a center of the contaminant removing member and the other end protrudes outside of the cyclone body through an inside of the grill body. The operation lever moves the contaminant removing member upward and downward.
