Roomba Blink Error Codes

The little light to the left of the Clean light on the 500 series, which if it is there can look like either a little Roomba or an exclamation point is called the Check Robot light (according to the Customer Service rep on the phone who e-mailed me the info below). 

If your Roomba’s CLEAN light is blinking orange and the Check Robot light illuminates, the robot is experiencing a charging error. The Check Robot light will blink out the error number every 2 seconds. For example, if the robot has an error code 2, it will blink twice, pause for 2 seconds, blink twice, etc. 

Please watch your robot when the CLEAN light is blinking to determine what error code your robot is displaying. Please respond with this information so that we can assist you further.
