You should definitely know that these do not have a float shutoff like a Shop Vac, so if you suck up too much water, it will suck into the motor. And these use a thru-foo motor unlike the later models that are bypass cooled (vacuuming air never touches upper part of motor, uses separate cooling fan and vents on machine), personally, that combined with the woven hose, I would not recommend using this machine for wet pickup, and I wouldn't personally use any of my vintage Silver King machines for it either. In an emergency if it was all I had, I might, but I have more things I'd feel comfortable using before that, including newer models of Silver King.
