I called Marina Pool and Spa today and spoke with Margaret with the idea that I was ready to order a dolphin Nautilus CC Plus for my pool and she told me that they have changed the design and they are going to be discontinued! Her suggestion was to get a Pentair Warrior instead of the Dolphin unit. I know and respect her reputation in the group, so I am not worried about bad advice from her, but I just have to ask the group about this. Who all has a Pentair Warrior robot? How long have you had it? What are your thoughts on them? Should I be considering upgrading to something different?
