New pool owner: Which Robotic cleaner??

[tiffnie903]

I have a 60,000gal in ground pool and I'm not sure which robot cleaner I should get. I've been looking at the Dolphin line.. I want it to climb and clean water line too.

Dolphin M400/500

I’m with you. Having a 19k pool about to break ground and I don’t know what to get. The M500 bc it’s the top of the line or s30i or even the Polaris?
