What reviewers found
Betta SE Plus
- Bob Vila (tested) (4.6/5): Best Overall of seven skimmers tested over about two months in residential inground pools. Easy to set up and removed more leaves and floating debris than any other model. Rated ease of use 5/5, performance 4.9/5, value 4/5. The tester's earlier Betta SE stopped working after about 12 months. Source
- The Pool Nerd: Used in the reviewer's own pool; the surface was clear of leaves, bugs and trash after a few hours, and he went weeks without skimming by hand. Rated Pool Nerd Approved. Says little changed from the SE beyond backup charging, for about $30 more. 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
