Absolutely not. They have a finger-thick cable that could strangle somebody,not a thick, 1.5" stiff hose, and run 29 volts. Both Dolphin and BD say you should NOT enter the water while they are operating.

2. What happens to the robotic cleaner, if you leave it in the water indefinitely? For example, as compared to the polaris 280, which can stay in the pool all summer.

No. It makes no sense, either, as you need to remove the robot to remove and clean the filter. You will void your warranty, too.

Thanks Webfeet.
These things are rather different than what you are used to. They require a minor bit of setup, then run nicely (when they work).
