I use a medium sized, two bagger for my shop. I also have valves at each tool so I can shut everything but the tool being used down to increase suction. It works very well that way. I even have the main line run across the ceiling to keep it out of the way. Make sure you put in a floor attachment so it picks up what your floor sweep picks up - no more dust pans,
