The answer

What to know.

The blue ambient LED on the front of the EON™ 100/120d is for ambiance only. You can change the ambient LED intensity through the Maytronics One app Settings.

The panel interface has a power LED indicator, four cycle indicators, a battery indicator, and a connectivity indicator.

The battery LED indicates the battery status. When all 3 bars are lit up in solid green, the robot is fully charged. The battery LED will blink green while charging to indicate its charge level.
