RYOBI introduces the 6" Hook and Loop Backer to our cleaning category. This backer is compatible with our 6" microfiber, knit microfiber, lambswool, and sponge heads (sold separately). The 6" Hook and Loop System provides quick change adaptability with a variety of sponge and cloth heads. 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" Hook and Loop Backer.
