## What reviewers found

### Beatbot Sora 70

- Reviewed: Cleaned floor, walls, steps and the Baja shelf and consistently beat other robots the tester had used, but did not pick up every leaf or seed pod and lost app connection underwater. [Source](https://www.reviewed.com/home-outdoors/content/beatbot-sora-70-robot-pool-cleaner-review)
- Techaeris (9.1/10): Handled floors, walls, waterline and surface in one session in an above ground pool; slow, its surface jets can push sinking petals down, and the reviewer says it will clog in an overgrown pool. [Source](https://techaeris.com/2026/07/04/beatbot-sora-70-review/)

### 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](https://pcworld.com/article/3084901/maytronics-dolphin-eon-120d-review.html)
- 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](https://www.thepoolnerd.com/best-cordless-robotic-pool-cleaners)
