I have a Polaris 280 with assist pump in a 18 x 36 Salt pool. At best the Polaris performance is spotty and on bad days - a joke. Repairs at about $35 each are frequent and it is just 2 years old. I have been looking at the electric robotic cleaners and I am convinced they will clean just fine. What I am concerned about is how reliable is each model. I would like to hear what experience people have with using this type cleaner. I am leaning to Hayward Tiger Shark just because they replaced a color logic light at the edge of warranty and were helpful with the process. I have read most of the features and have decided I dont really want the remote control - I AM NOT GOING TO SIT AND WATCH THIS THING CLEAN. Thanks for taking the time to read and hopefully you will give me the benefit of your experience
