I'm looking at buying a wet/dry vacuum. So far I favor the plastic-body variety, because I'll be able to bang it a little while dragging it around through its wheels, without constantly worrying that the body is getting dented.
I also favor the smaller capacity ones, because I'm expecting that a pump labeled "peak 2 HP" will have more than enough power for my applications: cleaning the garage floor and the inside of the car.
Yet I'm concerned about the noise. I hate that the Hoover-branded one I use at home is awfully loud. Does a plastic body (instead of stainless steel) mean more noise in a wet/dry vac?
What about the volume? One reviewer writes that the larger the capacity, the lower the noise. That doesn't make sense to me. Could larger-capacity wet/dry vacuum indeed be less loud than smaller ones?
