RYOBI introduces the 6" 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" 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" Knit Microfiber Head. 6" Hook and Loop Backer Sold Separately.
