New here. Best Booster Pump Pool Cleaner

25K in ground 4 years old. Came with Polaris 280 that has been nothing but problems starting at the 2.5 year mark. I have spent a ton repairing and rebuilding it and could have bought new for less. It broke again, husband told me to buy new and not repair. In an older pool, I had the same cleaner and it worked for years with minor repair. My pool repair guy says another Polaris 280, they are the best. I am reluctant and would like to hear from others! Thank you!
