The red plush cylinder of the original Cecil Watts Dust Bug definitely does NOT rotate.in use. You can turn it a bit every few months to evenly distribute wear. This from another old timer. (Bought mine when it first came on the market.)
A one time A-T sold a similar device with a grounding wire. It had a metal arm vice the Watts' plastic arm. Don't remember what it was called but it worked the same and looked nicer.
Hint: If yours moves too fast toward the record center, move the mounting base a bit further away from the turntable center so that the stiff bristles underhang the spindle. This produces an outward skating force.
