Robotic cleaner for tightly curved wall?

[lskipdive]

I've been doing research on robotic pool cleaners, and understand that they are able to climb curved walls on free-form pools as long as the curve is not "too tight".

How tight a curve is too tight? I've tried calling manufacturers but haven't had any luck.

The wall of my 8' diameter spa protrudes into the deep end of my pool. This wall is a real pain to brush down and I need a cleaner that is able to tackle this 4' radius curve.

Anyone have a positive experience with robotic cleaners on a wall like this?

Thanks! Lee

I have about the same design, my robot works great on my free form pool. It does not clean every inch of every wall but I don't think any cleaner, suction or robot does.

I have several fairly tight curves in my Grecian style pool. My Dolphin Triton Plus handles these with ease.
