In-floor cleaners?

I am looking at building an in-ground pool over in then next couple of months. Several builders are proposing In-floor cleaners.

I have been using a Robot at my last home. Has anyone had any experience with In-floor cleaners? How to they work? In then long run, do they make daily maintenance easier?

Lastly, is it worth the cost? I probably replaced components in the robot cleaner every two to 3 years? Is there much to go wrong or break with this type of system?

See post #3 here: http://www.poolforum.com/pf2/showthr...ystem-problems for PoolDoc's opinion from 2014.

Thanks for showing me the link. After thinking about it some more and a weekend of rain I am wondering how these thinks can handle the leaves and junk from the trees. Maybe they can handle pollen and light dirt.
