I have a Dolphin A30i which every week I roll out, plug in and put the cleaner in the pool every Friday. It then does it's scheduled cleaning cycle. There has been a contractor working in our neighborhood repairing the sidewalks. Last Friday, he not only managed to dig up my Internet connection, but also chopped up three sprinkler heads. Guess what? The Dolphin did not start it's cleaning cycle. It appears that for the WiFi enable units, it gets the time and date from the Internet. I was able to start the unit using the cycle start button on the power supply.
