We have 2 of the 12 gal. Shop Vacs from Lowes at work, and I also have one at home. The motor has burned out in two of them, but Lowes has replaced them with no questions asked. They were the $29 sale specials too, and the replacements were priced much higher not being on sale at the time, but they still gave me new replacements. The warranty is three years I believe. They have adequate power for our use, both wet and dry. If I were buying new though, I would probably go with the Ridgid just due to the great reviews they get. I have seen several contractors using them, like for instance the pool company that installed our salt system last fall used a small Ridgid to blow out the lines instead of an air tank or compressor. One difference I think is that the Shop Vac has the option of using a bag inside but I'm not sure the Ridgid does, if that makes any difference to you. At work we use one with a bag for dry only, and the other one without a bag for wet work.
