A remaining water suction device may include: a suction nozzle, a water separation chamber configured to be connected to a discharge port of the suction nozzle and provided with a water discharge port and an air discharge port, and a buffer tank configured to be connected to the water discharge port and store water separated from the water separation chamber. The remaining water suction device may include a water transfer pump configured to transfer the water stored in the buffer tank, a water storage tank configured to store the water transferred through the water transfer pump, a suction fan configured to provide a suction force to the air discharge port, and a suction motor configured to drive the suction fan.

A multi-functional window washing and wiping device comprises mainly a device body and a retractable rod connected to the device body, wherein on the device body are disposed a toothed gear assembly comprising a plurality of toothed gears and a vortex rod for driving the toothed gear assembly, whose two ends are pivotally connected to wheels disposed on two sides of the device body. At least two tube bodies are disposed above the device body. When using the present invention, assemble a cleaning tool such as a brush, a sponge, or a piece of cloth on the toothed gear assembly; input detergent and water via the tube bodies; and hold the retractable rod, place the device body on a glass window, and move the device body along the glass window. The purpose of washing glass windows in buildings is achieved by rolling the cleaning tool by driving the toothed gear assembly via wheels or a motor without the risk of having window washers hang in mid-air.
