Easily remove stubborn dirt & grease using the MicroTwist MAX Mop Refill. Tangle-free microfiber strands trap & absorb dirt, dust, hair & 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 & 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 & throw in the wash. Refill is safe for all hard floor surfaces, including wood, tile, laminate & linoleum.
