## What reviewers found

### Dolphin Nautilus CC Supreme

- PCWorld: 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. [Source](https://pcworld.com/article/3134641/maytronics-dolphin-nautilus-cc-supreme-review.html)
- The Pool Nerd: 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.

### Polaris Freedom Plus

- PCWorld: Best cordless pick; averaged about 95% coverage over several weeks, ran a little over 2.5 h on the thorough setting, missed a corner patch and some step leaves, and Wi-Fi dropped once underwater.

- The Pool Nerd: Runner up cordless pick in 2026; praises wall climbing and runtime versus many cordless units but says suction and scrubbing fade as the battery drains. [Source](https://www.thepoolnerd.com/best-cordless-robotic-pool-cleaners)
