I've had my Polaris 380 for about 20 years now and replaced the original booster pump after about 10 years. The current one seems to be on it's last leg, as it's shutting off after about 30 minutes, so I'm assuming the motor windings are worn out. Should I (or would you) spend the $450+ installation (if I don't just do it myself like last time) to replace, or is it time to upgrade the technology and move to a robotic cleaner? I don't want to spend a ton though, as we'll probably be moving next year sometime. It's a 36' long in-ground pool with approx 35 degree slope from shallow to deep end.
