The Lysol Cone Mop Supreme has an advanced microfiber head design that features two different types of fiber, each with built-in antimicrobial protection against odor-causing bacteria, mold and mildew. Its soft, tightly woven microfiber strings are spun from thousands of strands with millions of filaments, resulting in tremendous surface area and providing unsurpassed absorption performance. The wide, flat strands of microfiber and nylon scrubbies reach into tiny cracks and scrub deep down without scratching. It has a slender cone design that compresses and squeezes the microfiber, for unmatched wringing power with very little effort.
