What reviewers found
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
Dolphin Quantum
- The Pool Nerd (5/5): In a head to head with the Beatbot AquaSense 2, emptied the large basket about once a week on the weekly timer, left the floor noticeably cleaner after one pass and the water clearer with NanoFilters. Called it the stronger robot of the two. Source
- Poolbots (retailer review): In a test pool with algae and sludge at the waterline, a run of about 2 h cleared debris and improved water clarity. The cartridge was full of twigs, leaves and acorns after the run. It scrubbed above the 2/3 wall height cheaper robots reach. Source
