I am interested in getting a vac for a renovation. I already have a German-made HEPA type, so I am interested in one useful for rough, wet/dry type usage. I am considering getting a Shop Vac QPV pump unit, for its additional water-removal capabilities. The basic questions are:
Big wheels versus small - how much better are the units with the large back wheels?
Stainless versus plastic - ?
Is the pump worth it?
What size is optimal?
The Stainless QPV with the big wheels is 10 gallons and $220. The plastic Ridgid, 12 gal, with big wheels is $150, and the basic versions are $110 and $70, respectively.
