My mother just bought a shop vac for the garage, but it also has a air blowing fuction. No more swirl marks from drying = Yay. and it gets the water out of all of those crevaces that leak all over your car when you drive up or down a hill.

 

be careful when using it as a blower especially if you been using it as a vacuum (think blowing particles that could be in the hose...maybe overkill but ya never know.
