The IRobot Roomba vacuum cleaners are distinguished by their construction thoughtfulness in terms of service. From the standpoint of diagnostics, the troubleshooting system provided below in form of an available table come to the rescue.
| Number of beeps after “uh-oh” | Likely cause | What to do |
|---|---|---|
| No beeps | A wheel is stuck or is not touching the ground | Pick up the robot, place it down securely on the floor and touch the clean button to restart the cycle. |
| 1 | The main brushes cannot turn | Turn over Roomba and remove the brush guard by pushing the two yellow tabs. Remove the brushes, clear any obstructions, and replace them again. |
| 2 | The side brush cannot turn | Turn over Roomba. Look to see if something is wrapped around the side brush. Remove the side brush with a screw driver and check for string or hair that may be wrapped around it. |
| 3 | The vacuum cannot run | Remove and empty Roomba’s bin. |
| 4 | A wheel motor cannot run | Your Roomba may be stuck or something may be wrapped around a wheel. Look for something wrapped around the wheels. Push them in and out and make sure they turn easily. |
| 5 | The cliff sensors have failed or are blocked | Turn over Roomba and clear any debris that might be caught underneath the front bumper in the cliff sensors. You can also use compressed air to clean them out. |
| 6 | Wheel obstruction or robot attempting to drive over an obstacle | Turn over Roomba and remove any obstructions that prevent the wheels from seating all the way up into Roomba’s body. Also, remove any obstacles that Roomba could drive over. |
| 7 or 8 | Not applicable | Roomba’s beep codes do not include 7 or 8 beeps. If you are getting an error with 7 or 8 beeps, try counting again or contact iRobot Customer Care. |
| 9 | Sensor error | Please contact iRobot Customer Care. |
| 10 | Roomba is stuck | Pick up Roomba and start it again somewhere else. Use a virtual wall or other barrier to keep Roomba away from the place it got stuck. |
