Made of synthetic yarn designed for maximum absorbency, release and durability. Ideal for aggressive soil loosening and dirt trapping. Perfect for use on short looped nylon carpet and is extremely versatile as well. It can be used to clean with low moisture shampoo and solvent-based chemicals, or spray carpet and run the bonnet over it to wick up moisture and soil to leave the surface completely dry within an hour. For use with rotary floor machines with speeds of 175 to 300 RPM.
