No trees for several hundred yards but the wind always blows and my pool seems to be a magnet for the ones that go airborne.

I had a dolphin which needed constant attention --- like a spoiled little brat, you couldn't turn your back because it got stuck and actually wore the color off the liner in spots.

The Aquabot T-4 solved all the problems and has been super reliable. Aquabot has also been responsive to all my inquiries and has even supplied some parts free that they thought might be causing a symptom of my inquiry.

The T-4 was expensive but I would recommend it. Buy once --- it's cheaper in the long run.
