[0009] A preferred technical solution is: a one-way valve is provided in the vacuum tube, and the one-way valve is configured to open when the vacuum motor is started and to close when the vacuum motor is turned off.
[0010] The preferred technical solution is: the clean water tank is a special-shaped barrel structure with a U-shaped cross-section and is configured to be detachably buckled on the side of the vacuum tube.
[0011] The preferred technical solution is: the sewage tank is detachably mounted on the host.
[0012] The preferred technical solution is: it also includes a battery pack, which is detachably mounted on the main unit and is used to supply power to the roller brush drive mechanism, the vacuum motor and the water pump.
[0013] Due to the application of the above technical solution, the utility model has the following beneficial effects:
[0014] The utility model proposes a floor scrubber with an extended air duct, which extends the length of the vacuum tube by arranging a clean water tank between the vacuum motor and the sewage tank, thereby reducing the possibility of sewage being sucked into the vacuum motor; and, a one-way valve is arranged in the vacuum tube to avoid the problem of sewage backflowing into the vacuum motor when the vacuum motor stops, thereby shortening its service life.
