Ok so my trusty 20 year old craftsman 5 hp shop vac has finally decided to quit on me. I have to say it was a super sad moment when I first started to smell those electric eternals start to omit that I'm about to catch on fire aroma. Nothing says good bye like burning wires. Ok to the point. I am looking for a new one and the cordless technology is calling my name. I dont want to pull the trigger if the cordless ones have a significant decrease in suction. Wondering what some of you had success with and what to stay away from or if I should just get another corded one. Thanks
