I also have the PC 333. I always connect it to my shop vac for maximum dust collection performance. This past year I added the Oneida Dust Deputy Cyclone to the shop vac as a prefilter. It does a great job collection the dust. I don't remember the last time I had to clean out the shop vac. The cyclone keeps the shop vac performing at it's peak and really helps keep down the finish sanding dust.
