Tiny microfibers penetrate microscopic surface pores of most floors/walls. Hooks along each fiber act as tiny brushes scraping up dirt, dust, and other soils. The microfiber has a positive charge, which attracts negatively charged dirt particles. Once dust is attracted, it is trapped and held in the mop so as not to redistribute particles around the room. A microfiber pad holds up to six times its weight in water and is also launderable/reusable.
