I would like to hear recommendations for a medium duty wet/dry vacuum
to be used to clean up an unfinished basement concrete floor and
cleaning out four door sedan vehicles.

Are these rated at continuous duty horsepower? Going to stores later
today (or tomorrow), in time for weekend cleanup tasks.

I am thinking COSTCO, Home Depot, and SEARS. About $100.US maximum.
Any review articles for reference ?

Thanks.
