2000 rpm burnishers are not worth beens. They pull too much current to be useful. That's why they have the idler wheel on the front to prevent the pad from making any kind of serious contact to the floor. You'd be much better served with a 1500, 1200, or even a 1000 rpm machine. You really need to have some pad pressure on the floor to be useful for popping a shine, and a 2000 rpm machine can't deliver that on account of the idler wheel.
