I have a Polaris 360 that is 3 years old, this summer would be it's 4th year to sweep the pool, unfortunately it's DOA. It lays on its side at the bottom and doesnt move.
The wheels kinda try to move, they rotate very slowly but not enough to move the unit when its in the water. I have replaced the drive belts because they broke last year. At another forum it was suggested that it was on its side because the float probably had water in it, so I replaced the float but that hasn't seemed to help as it still lays on its side.
Pressure is not an issue as it gets plenty. There is a strong jet of water at the thrust jet and the "tail" and at the backup valve. The main pump for the pool is a 2 1/2 horse power that has always provided more than enough pressure.
I'm guessing its a gearbox problem?
Any suggestions would be much appreciated
