Jim,

      Neither the Roomba nor robotic pool cleaners are "randomly autonomous". They follow programmed trajectories and react to external stimulus.

I consider the Hayward as randomly autonomous as a Roomba, which I think was classified as a Robot. One key difference is that it will not "back-up" when bumped in the front (a programmed decision for a robot) Instead, it just slowly turns to the right until it reorients itself into a clear path.  The simplicity of its operation is admirable; Robot, or Not!

Jim, I'm pro-environment, but I've also studied biology, ecology and evolution. Speciation happens because environments change, so species are not all equal. Right now, to the jellyfish on the coasts of Korea, that means humans happened. Unless jelly-cide messes with the local ecosystem and has unexpected harmful results--as sometimes occurs from human interference--the genus overall doesn't have anything to worry about.

Jim,

       Unlike the micro-controller based electric pool cleaners, your suction powered cleaner is not a robot - it has no decision making process or pre-programmed actions.

Laughing !!   It's a good thing I'm not an environmental fundamentalist extremist, or I'd have to object at you casting judgment on the value of a species! But, I'm not, and I don't, so we're good!

I thought the artists's conception of CoralBot looked a wee bit unstable, too. But as we've discussed in several comments elsewhere, artists don't always have all the (engineering) data at hand.

Jim, it's total jelly-genocide--that's the idea. I don't like messing with Mama Nature at all, but in this case, there's not much to like and this very sucecssful species has been around a long time.

The in-pool cleaner I have is the Hayward Navigator; Using no power cord, its cleverly designed to use the suction power of the attached vacuum hose to mechanically convert the suction action into a walking action, using two offset cams like a bicycle pedal.  The device walks around the pool constantly, as long as the pool pump and filter are on for the day.

Looks un-seaworthy

The Coral Bot Nessie 4 shown in the first slide, just doesn't look like it would maintain a level buoyancy; It looks front-heavy, and apt to roll ,,, like the pitch and yaw would be very difficult to maintain. Was that model actually reduced to practice-? (image looks like a rendering)
