Overview

Wybot calls the S2 Solar the first underwater solar-powered robotic pool cleaner. Its dock hangs on the pool wall with a solar panel on top, and the robot docks and recharges itself between runs instead of being lifted out. Independent testing by Pool Robot Lab found solar charging too slow for regular use, so the DC adapter is still needed. The Vision version adds the camera from the C2 Vision. It was succeeded at the top of the range by the self-emptying S3.
