PROBLEM TO BE SOLVED: To provide a vacuum cleaner in which a cleaned surface can be consistently cleaned and damage on an obstacle, etc. is avoided. SOLUTION: A corner brush 26 which can protrude and retreat from a main inlet port 12 towards a direction crossing the traveling orientation of the cleaner body 1, is provided. A corner inlet port 41 which absorbs dust on the floor, is provided at the corner brush 26. By absorbing the dust on the floor from the main inlet port 12 and the dust on the floor by the obstacle from the corner inlet port 41, the floor can be consistently cleaned. Even if the corner brush 26 contacts the obstacle, the corner brush 26 can evacuate towards the rear side of the cleaner body 1 to avoid damage on the obstacle, etc. COPYRIGHT: (C)2005,JPO&NCIPI
