The Libman Tornado Spin Mop System is a convenient all-in-one mopping system. Designed with a large microfiber, machine washable mop head that absorbs and removes more water so your floors dry quickly. The heavy-duty bucket and spinning chamber work to remove water and dirt efficiently from the mop head. The lower handle is precision-molded and impact-resistant. You can unlock and push the handle down once for a damp mop or more times for a drier mop. The Libman Tornado Spin Mop removes over 99% of staphylococcus aureus and E. coli on ceramic tile and wood floors when used with water.
