It is up to the user to use it but with the Wiggle Table activated you can clean a lot of the GBC Balls out from the Pusher Table. It is fun to watch the GBC Balls go from left to right and back to front. Organized chaos we call it here and I think that pretty much sums it up. Note that the speeds on all motors in the videos as not to full speed. Something builders can play with themselves to fit their need.
