Can someone explain how adding 3 Dust Deputies and a large bin, likely 10 gallons or more of volume to a shop vac increases "suction"? I have been puzzling over this one. There is no explanation that I can find on the Oneida site other than instructions on how to gang these Dust Deputy units together into this Jules Verne/Rube Goldberg assembly functions. I don't want to pass judgment, it may work as advertised, but I don't see how.
