A gripping structure is provided on one side of the operating rod 5, and the other side is connected to the cleaning floor brush 3, so that the user can hold one end of the operating rod 5 to operate the cleaning floor brush 3 to clean the floor.

[0026] The clean water tank 4 is fixed at the lower part of the operating rod 5, and supplies water to the roller brush 2 through the water channel assembly 1. The roller brush 2 and the water channel assembly 1 are installed on the cleaning floor brush 3. After starting the floor scrubber, the roller brush 2 will start to rotate and clean the floor. At the same time, water will also start to be pumped from the clean water tank 4 to cooperate with the roller brush 2 to clean the floor. In order to enrich the functions of the floor scrubber, two water channels are set in the water channel assembly 1 of the present application, including a first water channel and a second water channel. The first water spray port 17 of the first water channel faces the roller brush 2 and sprays water directly to the roller brush 2. The second water spray port 18 of the second water channel faces the front of the roller brush 2 and sprays water to the ground in front of the roller brush 2.

[0027] like Figure 2 As shown, it also includes a water supply control component, which includes a waterway switching switch 7. After the waterway switching switch 7 is triggered, the water supply state of the clean water tank 4 to the first waterway or the second waterway is changed. The waterway switching switch 7 is at least triggered by a foot pedal. The water supply state includes a first state and a second state. In the first state, the water supply control component controls the clean water tank 4 to be connected to the first waterway and not to be connected to the second waterway; in the second state, the water supply control component controls the clean water tank 4 to be connected to the second waterway and not to be connected to the first waterway. The water supply control component controls the water outflow of the clean water tank 4, and selects one of the first waterway and the second waterway for water supply, so as to avoid the water in the clean water tank 4 being used too quickly due to the simultaneous water supply of the two waterways.
