I had a Dolphin Dynamic with remote. Still have it with one bad motor if anyone wants to buy it

Although reliable over that time there were two really annoying issues: removing it from the pool and cleaning the bag. To remove it from the pool you drag it to the side then flip it over and pull it up by holding the treads or body. It's really heavy and messy with the water spilling out as you pull. If you just pull it by the handle the sediment falls out the bottom. The bag cleaning is not fun. My kids call it changing the diaper. After you pull the bag you have to spray it out really well to remove the sediment. About once every couple of weeks I would run it through a wash cycle too. But, other than those grievances it did a great job cleaning the water. I often wondered if my sand filter was doing any good as the cloth robot bag cleaned things up so well. One other downside is all the bad stories I've read about Maytronics service.
