What reviewers found

Beatbot AquaSense 2 Ultra

Android Authority: Editor's Choice; pulled more debris, including small rocks, from an already clean pool than other robots tested. Downsides were bulk, price, and one failed charge due to wet contacts. Source
Reviewed: Did an excellent job on bottom and sides and left clear water, but could not clean the shallow tanning area or Baja shelf, lost Wi-Fi underwater, and its near 30 lb weight was hard to haul. Source

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
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. Source
