I have been using a shop vac as a central system for about 15 years and I
would not trade it for nothing. Somebody mentioned fine dust getting
throught the filter. That has not been a problem and my system is not
vented to the outdoors like the central vacs are. The only problem I find
is that when the filter is clean it is hard to clean the floor the brush
wants to glue to the floor.

You must match the tools to the job. If your floor brush is gluing down, you
have the wrong brush. Vacuum cleaners work ONLY when there's air movement,
so a good brush will provide a large volume of air movement without
attaching to the floor. If you achieve the same results by slowing down the
process of air movement, you also slow down the process of cleaning,
lowering the quality of the job. Think of it this way. Your brush will
move over the floor effortlessly if you don't turn on the system. That's
the direction you're headed when you run with a plugged filter. What's the
point? I use my system to get clean, not push things around. Go to a
commercial janitorial supply house and check out good floor brushes. You'll
be amazed that they actually work.. even without plugged filters.

One other thing. If you think your vacuum emulates a large industrial built
in unit, you're sadly mistaken. I've seen some of the largest of shop vacs
and they don't come close to the level of performance----not even close.

On carpet you can lift the carpet off the
floor. Once the filter is dirty it seems to work just fine. It was a lot
cheaper and I did use the proper piping and fittings with an adapter on
the
end for the shop vac.
