First time pool owner! I am overwhelmed and confused by the options for pool robots. I think we narrowed it down to Dolphin. We have a Leisure Fiberglass pool, it has a seat with spa jets, steps (deep and shallow end), safety ledge. Based on other threads it seems that most pool robots won't be able to climb our walls/ledges/seats. Is that correct? I don't wan to spend $1200+ on a robot if it won't work on our particular pool. So should I just get a basic one that just does floors? The Dophins on Amazon seem to be different then then ones on the Maytronics website (was looking at Naultilis CC Plus or Premier). I wanted to get off Amazon so that I could buy the additional Square Trade Warranty. Are they not as good? Any incite with our particular pool would be helpful! Thank you!
