<P>PROBLEM TO BE SOLVED: To provide a vacuum cleaner causing no left-over dust and being superior in the operability of a suction device. <P>SOLUTION: The vacuum cleaner includes: a handle to be operated by a user; a suction device 10 for sucking in dust from a surface to be cleaned by suction air from an electric blower; a control means for controlling a quantity of power supply to the electric blower; a state detection means for detecting an inclination etc. of the handle; a first rotary brush 11 disposed at a lower front part of the suction device 10 to rotate in a longitudinal direction; and a second rotary brush 12 disposed at a right end of lower surface of the suction device 10 to rotate in an almost horizontal direction. Based on signals from the state detection means, the control means drives independently the first and second rotary brushes 11, 12. For a front-back movement, the first rotary brush 11 is driven, and for a rightwise movement, the second rotary brush 12 disposed on the right side is driven, thereby easily moving the suction device 10 while interlocked with the handle. <P>COPYRIGHT: (C)2012,JPO&INPIT |
