I found this last evening. I decided to see what collection bags were available for my machine and learned that they are cheaper from shop vac. I still have to call them because the bag number printed in the operating manual is not on the site. Looking through the site there is a contest based on uses of your shop vac. I think that the tips are worth reading. Several I have already used for example cleaning drains and pulling wires through conduit. I liked the tip for using the machine for post hole digging. I don't plan to enter but I did enjoy reading the tips. http://shopvac.com/contest/index.asp
