After 10 years of good services, my best friend called Dophin 2001 decided to retire and went on quiet mode... what a bad start of season for me...It look as current cellphones which death is already embeded when you buy it...

So, I am looking for a new Friend, sharing the cleaning of my pool for the 10 coming years - at least !!! I have found two good articles, the Dolpin M5 and the Zodiac RV 5500 (or other numbers...). What is your experience between these two products ?
