ABSTRACT:
A vacuum cleaner with a single suction brush having a suction port contacting with a surface to be cleaned, and a vacuum generating device for generating a suction force at the suction port includes an air suction path connected by one end to the vacuum generating device of the suction brush, a dust collecting apparatus connected to the other end of the air suction path for separating and collecting dust and contaminants from an air drawn in through the air suction path, the dust collecting apparatus including: a cyclone-type dust collecting apparatus having a dust chamber of small capacity, causing the drawn air to whirl and thus separate the dust and contaminants from the air by centrifugal force generated by the whirling air, and a pocket-type dust collecting apparatus having a dust pocket of large capacity, and causing the drawn air to pass through the dust pocket, thereby filtering out dust and contaminants from the air, the cyclone-type dust collecting apparatus and the pocket-type dust collecting apparatus being alternately used in accordance with the characteristics of the space to be cleaned.
