I have a Pool Rover Plus for my in-ground pool (2 summers). I really loved it when it was working but it just broke for the third time so I am replacing it with a suction side cleaner. If you live by a service center it would not be so bad when they break but having to send a Rover back to NJ every time they break gets expensive. I think an electrical surge may have killed my transformer this time; my mistake for not unplugging it. Good luck with your Rover, I think you will love it unless it stops working and you have to send it back.
