Replacement heads for the 72-inch Court Force Super Duty Mop. Each set contains two (2) 36-inch heads, adding up to the 72-inch span of the mop. Utilizes the same revolutionary microfiber technology as the Bucketless Mat Map, except in a mammoth size to clean large areas in a much shorter amount of time! Microfiber technology enables the dual mop heads to "scoop" and "trap" soil off the court or mat. When applied, the microfibers split and literally scoop dirt off the mat. Fast, effective, and downright innovative.
