Ours continually wants to go as far away from the skimmer as possible and stay there. I figure it's because it gets pushed by the water coming out of the return jet. If I watch it, it has very little ability to go "up stream". It hasn't been an issue though because I'm home and I pull it to the far side of the pool every now and then and it works it's way back over to it's favorite spot in about an hour's time. I wouldn't leave it to run by itself for long periods. It also doesn't have enough gumption to move around when the solar cover is on. Not enough umpf to drag the hose along the bottom of the cover. I know of some that have much more power to do that, but they also take much more $$.
