SmartColor Micro Mops are easy to use, wet or dry, on any stone or tile floor, with or without rough grout lines. Heavy-duty, 15 mm microfiber pile absorbs up to six times its weight in liquid while gliding smoothly across nearly any flat, hard surface. Aggressive cleaning edges allow for a deeper clean, while requiring less water and less effort. These pads make it easy to color-code to specific tasks or areas, minimizing the potential for cross contamination. Machine launderable up to 500 times. For use with Unger SM40G and SM40R mop holders (sold separately).
