Corded waterline~$1,349Dolphin
Three brushes, a 2.5-hour default cycle and both a fine and an ultra-fine filter kit in the box put the CC Supreme at the top of the Nautilus range. It is rated for in-ground pools to 50 feet and scrubs the waterline. The trade is weight: at 24.6 lb it is the heaviest Nautilus here.

the maker lists no self-parking, so it comes out from wherever the cycle ended, full of water

Best for: A 50 ft in-ground pool with heavy fine debris, where lifting 25 lb is acceptable
A specification not listed here is one Dolphin does not publish for this model. It is left blank rather than estimated or borrowed from a sibling.
The two lists above come from the maker’s own specifications and this site’s arithmetic on them, not from owner reports. Where owner discussion has been read it appears in its own section below, so the two are never mistaken for each other.
The CC Supreme is where Nautilus shoppers end up when the features they want — waterline, more brushes, an app — push the budget toward $1,500, and owners who bought one mostly report that the cleaning justifies it.
The complaints are about the extras ageing: Wi-Fi and Bluetooth failing after a few years, and repairs accumulating on a robot that cost a lot. The scheduling question comes up too, because a weekly timer only makes sense if the robot stays in the pool.
It suits an owner who wants the fullest-featured Nautilus and plans to keep an eye on it. Fine filter cartridges are worth adding where dust is the problem.
Owners on gunite and pebble finishes report no problems and point to its grey rubber tracks. Scuff concerns come up in reviews but not in these owners' experience.
Owners find the app's scheduling at odds with advice to take the robot out after each run. Those who schedule leave it in; those following the usual advice start it by hand.
Owners report the Wi-Fi and Bluetooth dying after a few years, and repairs adding up over four years of use.
