Abstract

The present invention provides an electromotion cleaner with easily operation which can tell user whether the display / report device for reporting the existence of dust is in normal or not. The cleaner comprises a handle operation unit (operation assembly) 4 for drive the electromotion fan which provides suction force, a dust detecting device 11 capable of detecting the existence of dust, a control device 9 switching the suction force of the fan in several degrees by receiving the signal from the dust detecting device, and a display / report device 12 which receives signal from the dust detecting device and then on which the information can be displayed / reported. When user turns on the cleaner by using the handle operation unit after electrifying, the signal coming from the control device and dust detecting device makes the display / report device work for a while irrespectively. Then user can know whether the display / report device is working in normal before cleaning work.
