"This 17\" rotary floor scrubbing brush is meant to be used with our 17 inch rotary floor scrubbers. This brush is manufactured to exacting performance specifications for economical durability and peak performance. The polypropylene bristles will not last as long as our 17 nylon bristle brush, but they are an economical option when used with one of our floor scrubbing soaps. The poly bristles, on this brush, are actually slightly stiffer than the nylon ones, but they will wear down much faster. Take a look at our complete line of rotary scrub brushes and  for other options."^^<http://www.w3.org/2001/XMLSchema#string>
