Interested in getting another Dolphin...but am I screwed?

[C3Cl3N3O3]

I went through an ordeal last year getting a new liner installed. The pool company had to drain the pool and reseat the liner to fix numerous wrinkles. All that got sorted out, however there is another casualty. In the deep end I can feel a few rocks under the liner. I don't recall this with the previous liner or even the new liner before it was reseated, so I'm not sure what happened. The liner is very tight over those rocks. It is significant enough that you can feel it when brushing the pool.

So there seems to be a lot of swirl around pool cleaners cutting liners which have this vulnerability. Is this risk overblown? Or should I abstain from getting another Dolphin? I also have concerns about it getting hung up in that spot. I had a Dolphin Diagnostic previously that worked pretty well, but it used to get hung up on the drain a lot.

I have no interest in draining the pool and reseating the liner again!

I would think that any sharp points under the liner are a recipe for failure no matter what applies pressure to it. I wonder if a skilled professional could dive down there, cut the rocks out and then apply a patch to both sides of the liner? As you can tell, I have never repaired a liner so I’m just talking off the top of my head …. as opposed to talking out of a different orifice

I’m a broken record on this point - stay away from robots … they are money pits!!! Robotic cleaners are the Devil’s Spawn ….

Honestly, when submerged and experiencing buoyant forces, the robot weighs very little. It’s the suction from its water pump that holds it down. The brushes are soft rubber so that’s not really an issue. It’s hard to say for sure what the suction force is on a liner and how much damage that might do.
