I currently have a Dolphin DX4 that has done a great job cleaning my large L shaped pool. I have no trees within miles but lots of dust from neighboring farms and a whole lot of wind. Last summer at the end, we had a major storm and the power supply with the caddy was blown into the pool. Wouldn't turn on but after sitting a long time, got the power to go on. Great. Put the unit in this summer and the cleaner moved a few feet, climbed a wall and then stopped. I took the cleaner apart and there was nothing jamming it up. Screwed it all back together, took it out to try it out and now the power supply won't turn on. So, I don't know if there is 1. anything wrong with the actual cleaner and maybe it was the power supply the whole time or 2. if both the power supply and cleaner are toast. So. I am looking at replacing with either the Aquabot Elite, Dolphin Premier or the 300i. I love the idea of the multi basket with the 300i but can't find a local dealer that has it and can't find much online. I need the cleaner before 2 parties next Saturday and Monday as well. So, any advice you all have would be great. I have a vinyl liner if that helps make recommendations. Thanks.
