step three: when the double-roller floor brush is pushed forwards, the control unit 3 controls the front roller brush 11 and the rear roller brush 21 to rotate forwards, and the rotating speed of the front roller brush 11 is V1The rotation speed of the rear roller brush 21 is V2And V is1>V2；
When the double floor brushes are dragged backwards, the control unit 3 controls the front and rear rolling brushes 11, 21 to rotate backwards, and V1<V2。
Compared with the prior art, the beneficial effects of the dust sweeping method provided by the embodiment are basically the same as those of the double-roller floor brush provided by the first embodiment, and are not repeated here.
Specifically, in the third step, when the floor brush is pushed forward, V1＝R1，V2＝R2(ii) a When the floor brush is dragged backwards, V1＝R2，V2＝R1. In the first step, if the detection unit 4 can also detect the running speed of the double-roller floor brush, when the double-roller floor brush is pushed forwards, V1＝Vt(ii) a When the double-rolling floor brush is dragged backwards, V2＝Vt。
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention are included in the scope of the present invention.
