What size shop vac do I need?

For garage, car detailing, and workbench cleanups, reviewers consistently point to 2- to 5-gallon units, which are easy to store and move. For renovation debris, flooding, or construction dust, high-trust testers favor 12- to 16-gallon machines like the Craftsman CMXEVBE17595. Owners across forums note that larger tanks add power and capacity but become heavy and awkward to store.
