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 for forming a vortex flow of contaminant-laden air that is drawn in through the air inflow port. The cyclone body includes 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. An air inflow port is interconnected with the first connection pipe, and an air outflow port is interconnected with the second connection pipe. 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 is 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 for 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. A wire has one end connected to the contaminant removing member. A winding member is positioned inside the cyclone body, and the other end of the wire is wound on this reel. A rotary knob connected to the winding member through a shaft, and is positioned outside the cyclone body. A resilient member is disposed between the contaminant removing member and an inner bottom surface of the grill body for resiliently biasing the contaminant removing member downwardly.
