    Polaris 3900 leans on 2 wheel side. Runs fine without bag.

    My 3900, which I have had for 3 years or so now, has been running on it's side about 80% of the time lately and gets stuck by walls where they meet the pool floor. Needless to say, it isn't cleaning the pool bottom like this.

    I replaced the ballast float and the backup valve (it was constantly on). I also just replaced the internal drive mechanism with a gen 2 tune up kit. The water management system and the feed hose are from the original.

    Wheel rotations are at about 34 rpm.

    If I remove the bag it runs just fine. Stays flat on the bottom and does not get stuck on walls. I thoroughly cleaned the bag and put it back on but the issue remains.

    Does anybody have any suggestions? I'm at a loss.

    Thanks,
    -Chris

    Welcome to TFP, and glad you joined us!

    I've never had one of those, but people talk about them around here fairly often. Best of luck solving the issue.

    Thanks Patrick_B. If I can't get it fixed, I think I might start looking into a robotic cleaner. Lots to research if I go that route.

    Is it a polaris bag or aftermarket? I once bought an aftermarket bag that was too fine and the water didnt flow through well causing it to try and float.
