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
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. The site earns affiliate commissions. Source

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
