What reviewers found
Aiper EcoSurfer S2
- PCWorld: Cleared synthetic leaves in about 3.5 h with roughly 80% collected by the robot. 24 h of nonstop running used about 25% of the battery, and it kept a 10 h daily schedule through weeks of overcast weather. Slow, slightly underpowered, and the basket is hard to remove. Source
- Bob Vila (4.5/5): Named Best With App. Picked up leaves and bugs well and was compact, but app pairing was difficult at first and it sometimes got stuck after head on wall hits. Subscores: Ease of Use 4.3/5, Performance 5/5, Value 4/5. Source
Wybot B1
- Popular Science: Set up in under 5 minutes, cleaned in methodical lanes with wall and corner coverage, handled a sloped side without sticking, and self parked at the wall. Weighs 13 lb dry and the basket rinses quickly. Source
- WinFuture: Tested in a 5 m vinyl pool. Climbed walls and cleaned floor and walls, with a roughly 2 L, 180 micron basket. The waterline had to be cleaned by hand, and the unit must dry before its charging port is opened. No measured runtime. Source
