[0001] The present invention relates to the technical field of screen window cleaning, and in particular to a device and method for cleaning double-sided screen windows. Background Art

[0002] Diamond screens are widely used in residential buildings, office buildings, hospitals, and other settings. Over time, these screens are susceptible to contamination from airborne dust and lint. Regular cleaning not only eliminates ventilation inhibition caused by lint, but also effectively removes accumulated bacteria, mites, and other microbial contaminants, safeguarding indoor air quality. Traditional cleaning of diamond screens involves manual wiping or mopping with a cotton mop.

Due to the porous nature of screens, water stains and contaminants are easily squeezed to the back of the screen when manually wiping, making it impossible to completely clean them; 2. Manual cleaning often requires a damp wiping tool, and the wastewater generated during cleaning can cause secondary contamination in the room or on the windowsill; 3. Cleaning the outside of the screen is inconvenient, and leaning out to clean it can pose a safety risk depending on the floor. In view of this, it is necessary to design a double-sided screen cleaning device that can switch between internal and external operation modes. Summary of the Invention
