I ordered a Purvac Barracuda, supposedly one of the strongest units to run on 110V. The motor Spec shows 15 amps but the unit received motor plate says 12. X amps. There is no model and serial number on the unit but the motor specs match the Stingray model 2 levels down. I've tried 2 days to connect with these people. I had 1 voice message I returned twice but no return call or email. This unit is near as strong as my old. Sacammers.
