Dolphin Nautilus CC Supreme
Corded Wi-Fi Dolphin that scrubs floor, walls and waterline
Researched by Riley Hart · updated Oct 30, 2026
Is the Dolphin Nautilus CC Supreme worth it? A solid corded cleaner for in-ground pools up to 50 ft that scrubs the floor, walls and waterline and never needs charging. It costs $1,449 as of Nov 4, 2026, and 2 independent reviewers tested it.
A solid corded cleaner for in-ground pools up to 50 ft that scrubs the floor, walls and waterline and never needs charging. PCWorld measured about 90% debris pickup in an hour and 95% or more on the longest cycle. The catch is value: at $1,449 it carries only a 1 year warranty, while Dolphin's Premier and Sigma carry 3 years.
Best for: in-ground pools that want daily corded cleaning. Skip if: you want a long warranty for the money.

What independent reviewers found
- Tested for about 10 days. Collected roughly 90% of test debris in about an hour and regularly 95% or more on the 3.5 h cycle; saw no difference between regular and ultra clean modes. Cleanup of six filter pieces was tedious, the app was slow, and the 25 lb robot was hard to lift out.
- PCWorld
- Rated it Pool Nerd Disapproved on value, not cleaning: strong floor, wall and waterline cleaning with dual scrub brushes, but only a 1 year warranty and standard cartridge filters on an older platform. The site earns affiliate commissions.
