What reviewers found

Dolphin (Maytronics) Cayman

The Pool Nerd: Rated it best value; praised the weekly timer, corded consistency and top load MaxBin, noted it lacks an anti tangle swivel. Affiliate site with links to Dolphin dealers. Source

Dolphin Nautilus CC Supreme

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
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
