Solar Powered Automatic Cleaning: Harnessing 100% solar energy.During sunny days with abundant sunlight, the uninterrupted cleaning function ensures a spotless water surface. Once the battery is depleted, the robot automatically recharges during daylight hours. After charging, a simple manual activation suffices, whether rainy or overcast. This effectively prevents debris from settling at the bottom of the pool, liberating you from manual pool cleaning efforts. One-click start: Very easy to use, put it in the pool, turn on the switch and it will clean automatically. The design eliminates the need for hoses or other accessories when using the pool robot.
