I received a Craftsman Wet/Dry shop vac as a gift this weekend. It is a 16 gallon that can pump water out of it. It came with a bag that hooks to the intake hole (right after the hose). It is the first shop vac I have seen with a bag that goes in the canister. It looks like a giant house vacum bag. The instruction make it sound like I have to always use the bag when picking up dry debris. Is this true? It just seems like it could get expensive. A bag may be nice for the extra filtration when working with saw dust but when I am picking up larger and/or less messy things it seems like I am wasting money filling up a bag fast.
The other thing that seems peculiar that I am curious about is that they plug the blower hole and no air comes out it unless you intentionally remove the cap. It seems the exhaust is just coming out the seems of the lid. Is that right or am I mis using it?
I have to say that the instruction booklet left a lot to be desired.
Thanks Dan
