Light status table
| Light | Color | Pattern | Meaning | What to do |
|---|---|---|---|---|
| Light ring | Red | Pulsing | iRobot says a pulsing red light ring can mean Roomba is charging but the battery is too low to start. | Leave Roomba on the charging base until the battery has enough charge to start. |
Before replacing parts
Check the exact light name, color, and blinking pattern. Many devices use similar lights for very different states, such as setup mode, firmware updates, charging, connection attempts, paper jams, or failed pairing.
