Ordered my S300 from marina and it was delivered today. I was so excited to finally be able to clean the pool as we are at the 30+ day mark and having our first pool party on Friday. Well, it ran for 15 minutes and stopped. In the app it tells me there is a servo overload error and gives me the option to reset robot. I have tried resetting. Powering down and waiting doesn't work. I called marina and they "placed a ticket with Maytronics" and we have to wait and see what they say. I am furious. Waste of $850 and my pool is all sandy for the party. Awesome.
