I am now in my 4th season with my Aquabot Turbo. Still working great. The front brush developed a crack in the second season, and after I contacted customer support, they sent me a new one that arrived within a week. No charge! I'm still using the original bag too. I run it once a week for about 6 hours. I am so glad I bought it instead of the Dolphin. And I know I won't be doing any business with Smart Pool after reading this thread. Customer service is becoming a thing of the past with a lot of companies. Take the money and run. I for one am a faithful customer when I am treated right.
