- Cleans
- Floor to surface
- Power
- Cordless
- Runtime
- Up to 5 h floor
- Max pool
- 3,229 sq ft
A strong middle choice for cordless buyers who want surface skimming and step or ledge cleaning without flagship pricing. Reviewers found it cleaned better than most robots they had tried, but it is slow, it does not suit neglected or algae heavy pools, and it sinks if the battery dies before you fetch it.

A good fit for cordless buyers who care most about trapping fine dirt and want a robot that reaches 8 inch sun ledges. PCWorld found its filter caught debris very well but was a real chore to empty, and it sometimes missed corners and leaves on steps. Check the warranty, which is only 1 year on the Nautilus listing.

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
- 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
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
