Isn’t Emerson the same company that makes RIGID heavy duty shop vacs?
There appears to be a version of each of these branded Ridgid. I really want to get the smart cart version but the pricing is the same. Warranty is better with the ridgid and you get free shipping. This is not a deal, I would not buy from woot. I would expect that with a shorter warranty period that the pricing would reflect that, apparently not.
