RYOBI introduces the 6 in. Knit Microfiber Head to our cleaning category. With soft knit microfiber cloth, this accessory is perfect for cleaning granite, glass, boats, and other surfaces. The 6 in. Hook and Loop System provides quick change adaptability to a variety of sponge and cloth heads (backer sold separately). This system creates an anti-slip hold so the accessory head remains attached to the scrubber. These heads have a unique fitment to the backer that prevents accidental marring. The Triangle Connector allows the Hook and Loop System to be compatible with the RYOBI 18V ONE+ Power Scrubbers. Included in this set is (1) 6 in. Knit Microfiber Head. 6 in. Hook and Loop Backer Sold Separately.
