About to go onto my 3rd power supply. Purchased new in 2016, 1st supply went in 9/2016 covered under warranty. Power supply #2 started to flake out at the end of last year Sept. Deciding if I should buy another power supply $300, or a different unit. Its $300 vs 1300. I would buy something other than Maytronics but every thing I read recommend them. The cleaner works great I'm just suspect of the power supplies. Comment?
