This kit includes two flat mops, one handle and one holder. Polypropylene scrubbing strips for better grout line cleaning by creating scrubbing action. Additional layer of microfiber for fluid retention verses a layer of foam, making it more bacteria resistant. Excellent launderability. Sleek holder design allows liquid to run off, preventing growth of bacteria and can swivel to provide greater range of use. Flat base prevents pooling when applying finish. Superior velcro holds pads better and will not come off. Constructed of light weight aluminum.
