I'm wondering if there is a small hand held shop vac that works in the shop.I have a large vac for picking up sawdust from the floor and plane shavings. I would like something that will pick up sawdust from crevices in various machines. When looking at car vacs and such they always mention how good their machine is for dog or cat hair. I need something good for sawdust. Do you have something small and powerful enough that works? Thanks.
