An ultra-high speed burnisher with a pair of opposing polygonal burnishing pads creates less friction when burnishing a floor than a single circular burnishing pad or two circular burnishing pads. Less friction means that the polygonal pads rotate faster than circular burnishing pads and the polygonal pads create more heat on the floor finish than a single circular burnishing pad. The polygonal pads may be Y-shaped, flower-shaped, hexagonal-shaped, daisy-shaped, elongate like a lawnmower blade, triangular-shaped, square-shaped, pentagonal-shaped or cross-shaped. A method for producing polygonal pads and the resulting product of this method are also disclosed.
