The Polaris 360 is strictly a sweeper (pressure sided at that!) which means its not doing near as much as a robot would do for you.
A robot would allow you to get rid of any secondary cleaner pumps (saves a ton in electricity) and would pick up fine dust a sweeper just rolls over. A robot also can climb your walls and brush them. That alone makes ours valuable to Skippy, cause then he doesn't have to do it!
GIve us some details about your pool...size, composition, debris load..... we can help you find a robot to name and love....
