Recently replastered my pool and went with a dark blue finish. My polaris 280 is over 10 years old (one major and a couple minor rebuilds done by myself) but was looking at replacing it with a Black Max model to compliment new plaster. My main issue with the 280 is that the feed line quite often gets tangled. I have tried laying out the feed line in sun and even replaced the feed line with no major improvement. My pool is basically a 20x35 shallow 3.5 to 5 ft deep rectangle. Quite often the feed line will get a simple loop in which two floats come into contact with each other and the 280 does not seem to have the power to pull the feed line past the floats and straighten out the line, so the 280 does a U-turn and never makes it to the far side of the pool. I did not have this problem with the same unit in my previous pool which was a smaller kidney shape with 10+ ft deep end. The 280 will also never go up on the upper two steps (of 3 total) and rarely up onto the first lower step.
My question is that would moving up to a 380 give the unit a little more drive power to overcome the above issue (pull the feed line straight and avoid tangles better) as well as get up on the steps better?
I briefly considered the 480 and 3900 but internet is full of poor reviews on these units (maintenance headaches.) The general consensus is that the 380 is a little more maintenance prone than the 280, but that is OK with me if it will perform better in my pool situation.
