I have a buddy who sells them.....good machines, the down fall of brand new is they are under warranty for everything, as long as the motor stays dry.....
if you accidentally tip it over, bump it into something, lift it up and turn it over......the motor is shot, not covered under the warranty, and your out of a good chunk of change......the salesmen are instructed not to tell you about this.....invite an offer for a demonstration, knock the machine over and watch it fry....you will have an upset salesman and his boss too!
you think they would have a better design to avoid water ever possibly getting into the motor, the concept is a great idea, actually it's a fancy wet/dry vac, with a stopper to avoid water getting into the motor, for hundreds less!
you are better with a used one from a thrift store, you will save major bucks, and if it does fry, you didn't kill your bank account
just my opinion
