Degmesser: Same thing happened to me--no manual. I just phoned HomeDepot and the guy told me to open the vacuum itself (not just the carton) and look inside. The manual was there, inside. What a crazy place to put it! What if I had simply started it up and wrecked the manual with a water pick-up? Also, in order to open the vacuum dust container, you have to push down on the side handles first, then flip them outwards from the bottom. If you don't push down, the handles won't open! Hope you find the manual!
