We have a polaris 380 for our inground pool, 28k gallon.
The cleaner is about 4.5 years old and recently has not been picking stuff up from the pool bottom. I have counted the rpm's as suggested and they are low, but I cannot figure out how to change them so the rpms increase. I have pulled out the inline filter (the one on the hose) and it wasn't really clogged, though there was some stuff in there, I cleaned it out pretty good. It is rather rusty, don't know if that would have any effect on the rpms on the cleaner.
I also looked at the disconnect because I had read you could remove some sort of a blue washer-type thing that might increase the rpms. I couldn't look directly into where the disconnect goes because it is in the pool, underwater (obviously) and it is about 28 degrees here. I couldn't feel anything in the disconnect hole, I ran my finger around the inside but it didn't feel like there was anything I could pull out.
How long should our pool cleaner last? Is it worth having it repaired?
I also read that the polaris 280 is easier to maintain and fix; will it fit on the same connections that we have for the polaris 380?
I have had several bad experiences with pool companies and don't really trust them when they quote prices; it seems I can look online and find the parts needing replacement for at least 50% less then they want to charge. I do understand that they need to make money, but the last estimate was for a display board for my heater which I found new, online, for $175 and they quoted me $450.
Thanks for any help/guidance you can give.
