PROBLEM TO BE SOLVED: To provide a vacuum cleaner which easily, abundantly and continuously generates minus ions by a safe and extremely simple mechanism, and increases dust-collecting performance. SOLUTION: A suction chamber 15 having a rotating brush 2 is provided with a generating element 25 constituted of a material of which the electric charging sequence is different from the brush material 17 of the rotating brush 2. The generating element is charged by a frictional force between the rotating brush 2 and the rotator, and thus, ions are generated, and dust and dirt on a floor surface can be efficiently collected by the effect of the ions in addition to the scraping force of the rotating brush 2.
