<p>An electric vacuum cleaner includes a cleaner main body 11 housing electric blowers 15A and 15B. The electric vacuum cleaner includes a control means 16 capable of controlling driving of the electric blowers 15A and 15B independently of each other. The control means 16 has a medium mode and a weak mode in which other remaining electric blowers 15 than at least any one of the electric blowers 15 are actuated, and a strong mode in which all of the electric blowers 15 are actuated, and when switching from the strong mode to the medium mode (weak mode), the control means 16 actuates at least the electric blower 15 which was not actuated in the previous medium mode (weak mode). Cumulative operation times of the electric blowers 15 are made uniform, and the use life can be further improved.</p> |
