The original Cecil Watts Dust Bug used just a touch of his anti-static fluid (its name is lost in the mists of time) on the miniature plush covered barrel pulled along the record surface.
It does pick up a great deal of dust if you don't use a carbon fiber record cleaning brush before playing.
The problem with the original Dust Bug is that there is a separate cluster of stiff bristles which resonate as they scrape out dust and debris from the record as it rotates, and one can hear a tiny sound accompanying the sound from your speakers.
Reminiscent of the original antique acoustical record players where the tiny sound was amplified by the big cone. That's what is illustrated when you see Nipper the dog listening to "his master's voice" RCA old time record player.
Therefore, your thought about unwanted vibrations is correct for the original Dust Bug.
But, haven't seen the "new" version.
