Abstract

A vacuum cleaner including a cyclone style dust box provided in a vacuum cleaner main body, an outer filter portion provided within the dust box which forms a first cyclone space between the outer filter portion and an inner wall of the dust box, an inner filter portion provided within the outer filter portion which forms a second cyclone space between the inner filter portion and an inner wall of the outer filter portion, and a flange portion provided to the outer filter portion which extends towards an inner wall of the dust box. It is possible to achieve a high dust collection efficiency since two cyclone spaces are provided in a dust box interior.
