I am sure this question has been asked before, but here goes. I had a Polaris 180 which I was pleased with and I replaced the booster pump about 3 years ago. But after 17 years I need to replace the cleaner. I realized that I would not need the booster pump with the Polaris 360 but I am very familiar with the 180 and therefore would be familiar with the 280. My question therefore is ..... based on the experiences of the people on this forum, which model do you think will provide me with the better outcome ..... the Polaris 280 or the Polaris 360?
