Patent Summary
Surface-cleaning device using a porous plastic layer to keep the cleaning cloth dry and prevent floor damage. A thin, hydrophilic plastic sheet with 1–50 µm pores sits between the cloth and a reservoir, allowing liquid to pass through while blocking air. A syringe or pump applies under-pressure to the reservoir, sucking moisture from the cloth into storage. This design eliminates the need for wringing, reduces drying time, and avoids streaks by keeping the cloth consistently moist without over-wetting the surface.
