## What reviewers found

### Dolphin (Maytronics) Premier

- Bob Vila (9/10): Cleaned light leaf litter, tile line algae and storm dirt in a Miami pool, ran quietly at about 5 cents per hour, but was heavy to lift and the caddy and remote cost extra. [Source](https://www.bobvila.com/articles/dolphin-premier-robotic-pool-cleaner-review.md)
- The Pool Nerd: Names it the author's personal favorite after testing about 30 robots, citing suction, filter choices and the 3 year warranty. Affiliate site with links to Dolphin dealers. [Source](https://www.thepoolnerd.com/dolphin-premier-review)

### Wybot S3

- Android Authority: Mapped the pool on the first run, climbed walls and scrubbed the waterline without getting stuck, and docked and emptied on its own. Docking was unreliable in a shallow area until the dock was moved to a spot with a longer approach; setup required getting into the pool. [Source](https://androidauthority.com/wybot-s3-hands-on-impressions-3674143)
- GadgetGuy (8.5/10): Up to 2.5 h runtime and about 3 h mains charging; transferred debris to the 10 L dock cassette and lifted above the waterline on wall runs. Finer 180 µm and 10 µm filters do not clear through the auto transfer and need hosing about every two weeks. Value scored 6 of 10.
