Anybody ever seen a 12v Wet/Dry vac that’s worth a damn?

Universal means somewhere around 110V and whatever hz (they will even run on DC). Usually anything from 70 to maybe 130 or 140V. It might run on 220V for a few seconds before you let the smoke out. You can get pretty cheap 220 -> 110V transformers that would let you run quite a lot of 110V stuff.

I find this still works the best.
