How long did your Dolphin S50 last? We've had ours for 2 years and it leaked and got water in the motor and circuit board after year one. My husband was able to dry it out and fix it, but again this year it leaked and were not sure it's repairable again. It's quite expensive to replace every 1-2 years, especially when we only use it 1-2 times a week for 4 months a year. Hoping we just got a bad apple, but I wanted to hear how much luck everyone else has had with them, before dropping another $600+ on a new one.
