Floor scrubber with water level monitoring function

The utility model relates to a scrubber with a water level monitoring function, which comprises a clean water tank, a water outlet pipeline is connected onto the clean water tank, a buffer box is mounted on the water outlet pipeline of the clean water tank, a detection component for detecting whether clean water exists in the buffer box or not is arranged in the buffer box, and the detection component is electrically connected with a main control board of the scrubber. The detection component comprises two metal terminals extending into the buffer box, the two metal terminals are electrically connected with the main control board at the same time, and the main control board judges whether water exists in the clear water tank or not by detecting connection and disconnection of a circuit between the metal terminals. Through the arrangement of the buffer box and the detection part, whether clear water in the clear water tank is used up can be judged by detecting whether clear water exists in the buffer box, and
