You use a shop vac to clean your house? Doesn't it scratch the hell out of your wood floors and do a terrible job on carpet? Not to mention a lack of good air filtration...
Not at all. Wheels are the same as wheels you find on your average vacuum.
We don't have carpets and plastic wheels don't scratch tile or Laminate flooring at all. We have been using it for over 3 years.
Air filtration? It has a filter. Dust is everywhere anyways. Relax. Most people in this world live on sand/moldy houses...I'm not worried about it.
I actually JUST bought my wife a smaller one (4 gallon) vs current 10 or 12. Which will make the job easier as its much smaller etc.
You will NOT beat a suction of a Shop vac, Price OR warranty.
I went thru WAY too many POS vacuums to ever consider ANYTHING else (and that includes Dysons, Hoovers and Kirbys).
