I brought a Pentair Warrior se from Marina pool and spa. It broke about 1.5 years later. The motor unit was replaced under warranty and now has died less than a year later. Pentair will not cover it now that is out of its 2 year warranty period. I did take the warrior apart and found the impellar motor must have taken on water and was rusted out. Before the Warrior we had a polaris 280 that never broke but required I brush the pool which I didn't have to do with the robot. Not sure if I should just go back to a polaris suction cleaner or try another pool robot. I liked the robot but spending almost $1000 every 2 years if it keeps breaking kind of ridiculous. I know people have had better success with their robot than I did. Ideally there is a product that I can fix myself. Are aquabots easier to fix. If so what model is similar to the warrior se. Thanks everyone for their help. This resource and people in it have been amazing.
