This isn't exactly a money saving question but I wondered if anyone had a tip for emptying a shop vac that doesn't get that fine powder all over the place. I use the can vac so I don't have to buy bags and replace an upright every time a Lego goes awry. I empty mine outdoors into a large bag, but it still manages to settle over everything (especially me) and even drifts in the window if it's open. When I remove the filters it's like a dust storm. I even wear a bandana over my face bandit-style. Anyone have a good way to do it? p.s. I hate carpet.
