Easily remove stubborn dirt and grease using the MicroTwist MAX Mop Refill. Tangle-free microfiber strands trap and absorb dirt, dust, hair and moisture from hard floors. Double red bands prevent tangling for smooth mop coverage. Buffering pad on the mophead delivers extra cleaning power on stubborn dirt. Reusable and machine-washable microfiber head removes more than 99 percent of bacteria with just water. Extra-large size (18") covers more surface area in less time. Once done, easily detach from the O-Cedar MicroTwist MAX Microfiber Mop and throw in the wash. Refill is safe for all hard floor surfaces, including wood, tile, laminate and linoleum.
