The Tough Guy Wet Mop String Mop is a 24 oz. cotton mop head that attaches to a mop handle (sold separately). It has a 5" headband and measures 24" long when attached to a handle. The mop head is machine washable. This mop is designed for wet mopping floors and can be used with a mop bucket and wringer (also sold separately). It is durable and absorbent, picking up dirt, dust, and spills from hard floors. The cotton strands loosen dirt and distribute cleaning solution evenly. For best results, launder the mop head before first use.
