I have a Dolphin Apollo Plus, which as near as I can tell is a branded DX4 model. It has an auto start cycle to run every 1, 2, or 3 days, which I would like to use. But, the manual says "after each cleaning cycle take it out of the water to prevent accelerated wear and tear on its plastic parts". Makes no sense to give us a feature and then tell us not to use it. Do any of you keep your robot in your pool, plugged in? Thank you.
