I've been watching a "Cool Tools" marathon on the DYI channel. Just saw a neat look shop vac made by Snap On tools. It's basically an easy to carry box. It's called the Snap On Box Vac. Just wondering if any of you have ever tried one of these vacs and how it would work with wood ash. It does have a HE Hepa filter. My Bride would become a self-made widow if I spewed ash all over the house. I already stir up enough when I scoop out the ashes.
