In order to collect dirt, the floor scrubber is generally provided with a sewage tank and a vacuum fan, and when the floor scrubber works, the vacuum fan operates to suck liquid, dust and other dirt on a surface to be cleaned into the sewage tank. A traditional floor mopping machine generally judges whether a sewage bucket is full through a floater in the sewage bucket, and when the floater blocks an air outlet in the sewage bucket, a system judges the water level through pressure detection or electromagnetic induction and gives an alarm. However, in practical use, the float moves up and down due to the forward and backward movement of the product, and the float often blocks the air outlet when the sewage bucket is not full, so that the false alarm condition is easily caused.
Some improved floor mops employ two metal probes to detect whether the slop pail is full, and when the amount of water in the slop pail increases to make the two metal probes form a loop through the conduction of liquid in the slop pail, the system judges that the slop pail is full according to the current of the metal probes and gives an alarm. However, when sewage flows into the sewage bucket, the sewage is easy to extend onto the metal probe, and when the sewage contains strong electrolyte or fine particles, the metal probe is easy to be conducted to form a loop, so that the situation of misinformation is caused, and the use experience of a user is not improved.
