I bought a house with a pool, first one for me, and have enjoyed the experience. The pool came with cleaning robot, a Prowler 820, in the last two weeks I have been experiencing issues with the power supply unit, it shuts down for no reason, the unit will power back up after a period of time. The frequency of "shut downs" has increased. Based on the records I have, this is power supply unit I have is the 3rd one, the Prowler was purchased by the prior owner in 2013. Thanks
