Which is the best Pool Cleaner?

[PoolDanny]

I am looking at buying a new pool cleaner from www(dot)inyopools(dot)com. Can anyone tell me which one they think is the best to help make up my mind. I have a concrete inground pool

Let me know what you guys think. I do have all the proper suction lines, but am thinking the Robotic Cleaners look like the wave of the future.
