Pad conditioning brush?

[WRAPT C5Z06]

How do you properly use this while you're in the middle of polishing? The add shows it being dragged across the pad while the pad is spinning, or do you just scrub while it's not spinning?

Brush off the pad every couple passes to keep it clean.

Turn the polisher on a low speed like 1000rpm and drag from outside to inside and back.
