How To Know If Roomba Is Charging

Sometimes, I forget to switch the charger on once I plug in my phone—such a heartbreaking moment when I find it not to have charged. There are ways to know if Roomba is charging to avoid such a scenario with your Roomba.

When I got my first Roomba, it was challenging to distinguish between the different color indicators. So, how to know if Roomba is charging?

Check if your Roomba is charging by pressing the “CLEAN” button and observing the battery indicator color. When charging, the battery indicator will display amber color; a solid color of green means full of charge, and a pulsing amber color or red means low battery. The indicator light turns off after 60 secs for Roomba 700, 800, and 900 series.

If your Roomba shows a solid green color, the battery is fully charged and ready for cleaning tasks.  When your Roomba still charges, it will show a pulsing orange or amber color. Further, if your Roomba flashes a red color, it means the battery is running low.

In recent Roombas, the iRobot home app helps check the battery status. On the top right of the home app is a battery indicator, showing your Roombas battery status.
