I have a small, medium, large and wall Vac. Use the wall vac the most. If you are doing a lot of woodworking then a larger Vac would be better. Cleaning up small messes and your cars, I like the Craftsman wall Vac.
I have several(3) Shop Vacs as well as a built-in vacuum system I prefer the ShopVac.
The built-in system does not handle chips from the lathe or mill.
I bought this one, just haven't permanently mounted it yet. I have an ordinary Craftsman large vac too. It works great it just takes ups so much space.
