- 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.

- 40 ft long
The cheapest way here to get a corded robot on a weekly timer, which means no daily charging or hauling. It is light and simple, but Maytronics does not list waterline scrubbing, there is no app, and it is rated for pools up to 40 ft. Skip it for large or very leafy pools.

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) 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
