• Best For: Mercury 20" floor-machine users needing a poly-bristle pad driver for standard scrubbing and buffing.
• Highlight: Mercury 2105 20" pad driver with 1/2" poly blue bristles that grip and center the pad.
• Expert Note: Poly bristles resist solution and hold the pad flat for even wear; size the 20" 2105 driver to a matching 20" floor machine.
