When out with one of my friends yesterday, who also owns a pool, we were discussing this site, and the fact that I had bought a new robot cleaner for my pool and loved it. He looked at me and said, "you can't have a robot cleaner with a vinyl liner".
I did not read that with the owners manual and wonder if anyone could offer an opinion. I just spend a ton on a new liner, and for that matter, on the robot. Thanks..
