Rubbermaid Self-Wringing Ratchet Twist Mop with Blended Yarn Head, 54-inch (1818664). This self-wringing twist mop uses a ratchet in the handle to twist and wring water out of the mop head. Mop head has double tailbands and looped ends to minimize tangling. This mop is suitable for use in commercial and industrial applications. Handle is 54 inches (137.2 cm) long. Wet mops (also called string mops) consist of a mop head, a handle, and a method of attaching, or mounting, a mop head onto a handle. Mop heads are typically made of cotton, synthetic fibers, or blends of cotton and synthetic. Synthetic fibers withstand laundering better and dry faster, both factors leading to longer product lifespan because harmful bacteria grow in a damp mop. In traditional string mop construction, coarse strings of cotton yarn are banded at the head for connection to a handle, and the strings hang loose at the tail. This method is now referred to as "cut-end," to contrast with the improved method of looping the strings back to the head, leaving no loose ends to fray. Laundering is not recommended for cut-end mops. Other improvements include tailbanding, which ties the strings together close to the tail to reduce tangling and improve floor coverage. Mops are used for cleaning floors or for spreading an oil- or water-based floor finish onto a floor to protect the surface. Rubbermaid manufactures cleaning, organizing, and material handling products for commercial, medical, and industrial applications. The company, founded in 1933, is headquartered in Huntersville, NC.
