The Metabo Wet/Dry Vac (ASR 35) is designed for both the shop and the job site: You can set it to manual and use it as a shop vac, or set it to auto so that it's activated by a tool plugged into its onboard electrical outlet. The vacuum has a 9-gallon capacity, weighs 39 pounds, and is equipped with oversized wheels for easy transport. An automatic cleaning system extends the life of the filters by periodically knocking the dust out of them. It's sold with a 14-foot hose. A HEPA model is also available.
