I just got one of these as well for my 33x54 pool. I’m loving this little robot for sure. I put out a video here on RU-vid as well and will be doing another as I get more time with my Dolphin E10 cleaner. Great video mate.
They tell you only to use the cord that you need, don't through all the blue cord in the pool, only what you need. It works good only sometimes the cord gets tanagled.
It works much better with the main filtration going. What was on the seems was a bit stubborn, but once it finally cleared up i haven’t had that issue anymore. I would say it does a good job of getting the heavy debris into the basket but the silt and dead algae it doesn’t always catch but it keeps it suspended in the pool long enough for the main filtration system to get it. In some ways the shark did a better job, however it always missed certain areas. The dolphin will cover the entire floor and at least get it off the bottom to be Collected by the main system later.
