The grill assembly is located at an upper part of the air discharging passage of the cyclone body that generates the whirling air current from the air drawn thereinto and separates filth from the whirling air by a centrifugal force. The grill assembly, which prevents the filth from being drawn into the vacuum-generating device of the vacuum cleaner, comprises a cylindric grill body having upper and lower openings in which the outer diameter of the upper part is greater than the outer diameter of the lower part; the grill body also includes a plurality of passages formed in the cylindric grill body.
