What reviewers found
Betta SE
- Bob Vila (4.6/5): Named Best Basic. Called it the fastest skimmer tested, with solar charging that kept it running and ultrasonic navigation that rarely left it stuck. It occasionally missed tight corners, and the test unit's rear propellers stopped working after about 12 months (covered by warranty). Subscores: Ease of Use 5/5, Performance 5/5, Value 5/5. Source
- The Pool Nerd: Pool Nerd Approved and named Best Overall Pool Skimmer. Cleared the surface within a few hours, ran daily for several weeks with no jams, and the basket needed emptying every few days. The site earns affiliate commissions. Source
Seauto Shark
- PCWorld: Picked up about 85% of organic debris and over 90% of artificial leaves in a 3+ hour floor only run, scrubbed the tile line well, and docked at the wall every time. The app was buggy and a firmware update never completed. Source
- Pro Tool Reviews: In a 20,000 gallon in-ground pool it ran more than 3 h in floor only mode, about 5 h total, recharged in 2 to 3 h, crossed raised drain covers and cleaned in a linear pattern. The app kept disconnecting. Source
