What reviewers found
Aiper Scuba V3
- Bob Vila (4.5/5): About a month in a Florida pool: it identified debris and drove to it, pickup of algae and fine debris was excellent, and retrieval was easy; no surface skimming and premium price when not on sale. Source
- The Smart Home Hookup: Passed the 8 inch sun shelf test and praised debris detection, but even with the secondary filter it struggled with sending fine silt into the water column. Source
Dolphin (Maytronics) Nautilus EON 120d
- PCWorld: Tested the EON 120d: DebrisLock filter trapped all types of debris and coverage reached about 95% on the longest cycle, but emptying the filter was a huge pain, it missed corners, failed to start twice at first, and often flipped onto its back. Source
- The Pool Nerd: Notes the EON line cleans water as shallow as about 8 in with better than basic mesh filtering, but still requires hooking, lifting, drying and charging; Clicker retrieval is mentioned for the 120d. Source
