Abstract
In a cyclone dust collector and a vacuum cleaning device having the same, foreign substances can be prevented from being attached on an outer circumferential surface of a grill located at an outlet part, so that an inhalation force of the vacuum cleaning device can be prevented from being lowered. Also, foreign substances collected in the cyclone dust collector can be easily removed. The vacuum cleaning device includes: a cyclone dust collector, wherein the cyclone dust collector includes: a cyclone chamber in which air introduced through an inlet part is whirled and dust is separated from the air; an outlet part disposed so that the air from which the dust is separated is discharged from the cyclone chamber; and a grill that is rotatably disposed in the outlet part.
