This 20" microfiber mop head is just what you need to wash big vehicles (big trucks, RV's, airplanes) and cover ground in half the time. Keep a replacement mop head on hand to be used with the backing plate and handle. One side of the pad is microfiber "fingers" and the other is a tighter woven microfiber. Either side can be used. The microfiber absorbs 6 times the water as a cotton mop head. Use M90 Hawaiian Shine and your wash jobs will shine more and the water will sheet off more!!
