The in-depth review
The Nautilus CC Supreme is the version of the popular CC platform to buy when floor-and-wall cleaning isn't enough. It adds waterline scrubbing and ultra-fine filtration to the same reliable, easy-to-live-with robot.
What "Supreme" adds
Beyond the Nautilus basics, the Supreme scrubs the waterline and includes both fine and ultra-fine filter kits, so it handles everything from general dirt to fine dust. Selectable cycle lengths let you tune the clean, and it covers pools up to 50 feet. Underneath, it's the same proven CC reliability and service network.
The trade-offs
There's no app on this trim — you get a weekly timer but not phone control. It's corded, and at premium pricing for a no-app robot you're paying for cleaning and filtration rather than connectivity.

Frequently asked questions
Is the Dolphin Nautilus CC Supreme cordless or corded?
The Dolphin Nautilus CC Supreme is corded — it runs on continuous mains power through a floating cable, so there is no battery to recharge between cycles.
What does the Dolphin Nautilus CC Supreme clean?
The Dolphin Nautilus CC Supreme is rated to clean the floor, walls and waterline. That includes the waterline, where sunscreen and body oils build into a greasy ring. It is an underwater cleaner, so it does not skim floating debris off the surface.

It filters debris through a fine and ultra-fine filter kits. Rinse it after each cycle so suction and pickup stay strong.
