## 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 VRX iQ+

- PCWorld: Best corded pick; found 99% of synthetic leaves, missing one on a step, and was one of the fastest robots tested. Managing the power cord took extra effort. [Source](https://www.pcworld.com/article/2290595/polaris-vrx-iq-pool-cleaning-robot-review.html)
