I have a brand new pool and the Dolphin M400 is part of the package. I'm used to my kids swimming at my friend's pool while her vacuum is going. However, her vacuum plugs into a return and not into external power. The manual for the Dolphin says not to be in the pool while cleaning. However, it takes 2.5 hours to clean!! I'm afraid I'll struggle to find 2.5 hrs every day... with no one in the pool... when I'll be there at the end to take it out (I think I'm supposed to remove it as soon as the cycle ends). I watched an Aussie YouTube professional review of the cleaner (Dolphin pool cleaner review - by Healthy Homes TV Australia - YouTube) where the reviewer SWIMS WITH the Dolphin, observing it's cleaning function. So, now I'm thinking the manual warning is just in reference to cord entanglement. My kids are definitely old enough to watch out for that. Do any of you know? Is there an electrical risk to swimming with the cleaner or would it just be cord entanglement? Do any of you swim with your robot cleaners?
