Re: Ball posession: Roller (ball magnet) or vacuum?

Before going to the trouble of gearing it up (by "up" in this context I assume you mean higher speed at the impeller), you might want to measure your current draw with the 3:1 gearing when operating without a possessed ball. With a centrifugal impeller, the motor will be drawing more current without a possessed ball (more airflow).
