PROBLEM TO BE SOLVED: To provide a vacuum cleaner where power is controlled simply. SOLUTION: An electric blower 5 is supplied with power by a main-body battery 6. A brush motor 23 whose input voltage is different from that of the blower 5 is supplied with power by a brush battery 25. It is possible to separately control power to be supplied to the blower 5 and the brush motor 23 from the main-body battery 6 and the brush battery 25 respectively. Power is simply controlled since it is not necessary to change voltage in a plurality of steps according to the driving state of the blower 5 and the brush motor 23. COPYRIGHT: (C)2004,JPO
