The waste water is sucked into the rectangular groove through the fan assembly. When the window cleaning machine moves on the window, the third water collection tank is kept at the bottom of the working surface covered by the machine body by turning. At this time, the waste water flows to the side away from the movement direction of the window cleaning machine, and is guided into the water collection holes of the first, adjacent second and third water collection tanks through the inverted V-shaped diversion channel. The waste water is sucked into the wastewater tank through the wastewater pipe and the water pump, which can prevent the machine from slipping and prevent the wastewater from being sucked into the fan. Afterwards, the wastewater in the wastewater tank is filtered through the filter to become clean water. The clean water is sucked into the clean water tank through the clean water pipe and the return water pump, thereby realizing the water circulation of the window cleaning machine.
