My Polaris 9300 Sport needs a new motor block = big $$$ repair, as in near $600 So I need to research robotic pool cleaners (I want to stick with robotic). The 9300 Sport worked fairly well, so something along the same line in terms of features and performance would be good.
Any ideas on how to begin this process aside from the normal research? Any brands I should AVOID? Any brands that are considered better than others?
