The answer
What to know.
The Skimmi 200 and 300 have two charging options: built-in solar charging and the included external charger.
Solar charging
Skimmi gives solar power priority. Its built-in panel recharges the battery in sunlight, whether the robot is running or on standby. You can check the charging status in the app.
An energy sensor helps Skimmi find the sunniest area of the pool to get the most from solar charging.
External charger
When Skimmi is connected to the charger, blinking LEDs show the battery level. The LEDs light up as each battery level is reached. Once the battery is fully charged, all LEDs light up, then turn off.
The external charger is the recommended option for a full charge on cloudy days. You can also use it during winter or other periods of limited sunlight to keep Skimmi operating when solar charging conditions are not ideal.
