Uhhhh.... I'd like to change my opinion . Apparently, this thread was the kiss of death for me. My Dolphin stopped working this week. It runs for about 10 minutes and stops. What’s odd is that I can still remotely “drive” the unit around the pool, but the propeller on the top is not spinning. I tried running the unit without a bag in it to satisfy their support people. The same thing happens. I called SmartPool to get an RMA and I’ll box it up and send it back this weekend. I’m having visions of CarlD’s Dolphin nightmare . We’ll see what happens.
