<P>PROBLEM TO BE SOLVED: To provide a vacuum cleaner with a dust remover operated by a DC power source and a charging power source in which specifically, it starts and stops charging depending on a cleaning operation state, and during charging stop, the power consumption for charging is supplied to an electric blower to thereby secure a sufficient dust collection performance and give charging required for dust removal. <P>SOLUTION: The vacuum cleaner includes an electric blower 2, a dust remover 65, a first DC power source 67, a second charging power source 68, a power source switching/driving device 70, and a cleaning state detector 71 that detects the condition of the vacuum cleaner. Thus, the charging to the charging power source can be controlled depending on the state of the vacuum cleaner. <P>COPYRIGHT: (C)2012,JPO&INPIT |
