Reference numeral 12 denotes an operation lever pivotably supported by the case 11 and having a lower end extending from an opening on the lower surface of the case 11 to the lower side of the suction tool body 1, and a spring erected between the upper end and the upper surface of the case 11. The operation lever 12 is held in the neutral position by the biasing force of 13. Reference numeral 14 is a first switch arranged on the front side of the case 11, and 15 is a second switch arranged on the rear side of the case 11, which is the suction tool body with the suction tool body 1 placed on the surface to be cleaned.

小さくなり、電動機8の負荷が著しく低くなり、電動機
8の発熱が著しく減少する。The mounting distance between the first switch 14 and the second switch 15 is wide so that when the pushing / pulling operation of the suction tool body 1 is switched, the operating lever 12 pushes one switch to move the other switch. It takes a sufficient time for the pressing operation to be performed, and there is a time during which the electric motor 8 is de-energized even when the suction tool body 1 is quickly pushed and pulled. Therefore, for example, when the suction tool main body 1 is moved from the pushing operation to the pulling operation, the operation lever 12 moves to the first position.
The state in which the switch 14 is pressed is changed to the state in which the second switch 15 is pressed, and the first switch 14 also moves to the second position between both positions.
The switch 15 is also not pressed, that is, in the OFF state, and the driving of the electric motor 8 is stopped, so that the inertial force of the electric motor 8 is reduced or eliminated by the rotational resistance during that time. Therefore, compared to a configuration in which the rotation of the electric motor 8 is instantaneously switched from the forward rotation direction to the reverse rotation direction, the starting resistance in the reverse rotation direction when the operation lever 12 is switched is small, and the load on the electric motor 8 is significantly reduced. As a result, the heat generation of the electric motor 8 is significantly reduced.
