The sight of a flashing warning light on an expensive piece of kit is always concerning, sometimes for a good reason. The Roomba charging error 5 is often displayed as five flashing warning triangles and a two-tone “uh-oh” followed by a voice that may say “charging error five” with further instruction depending on the model.
What can you do about it?
Luckily, the charging error 5 is not something to be too concerned about and can be easily remedied. When you have a Roomba charging error 5, your battery is not charging properly. The best way to avoid this is to use iRobot batteries only. If you are using a genuine iRobot battery then the first step is to check your battery contacts and charging contacts. Check out the video below to find out more on how to d this:
Step 1 – Unscrew and open the Roomba
The first step is to make sure that nothing is blocking the battery contacts. An example may be the yellow battery pull tab. These images below were made by iRobot to help their users identify where the screws are located to open the Roombas. The image on the left is for Roomba 800 and 900 models. The image on the right is for Roomba 500, 600 and 700 models.
Step 2 – Clean the battery contact points
The second task is to clean the contact points and remove any debris that may be causing the charging issue on the battery itself. It is best to perform this with a clean and dry cloth. The green points on the battery identify the contact points.
Step 3 – Clean the Home Base charging points
Thirdly, it is important to check the Home Base charging contacts for any debris too. Do exactly as you did with the battery charging points and use a clean and dry cloth.
Step 4 – Test out results
Next, it is time to try charging your robot vacuum again to see if the Roomba charging error 5 is still displayed. In the vast majority of cases, it should be resolved, although in some it may persist. If it still shows then it may be worth trying to clean the battery contact points one last time to ensure nothing was missed.
Step 5 – Contact iRobot if all else fails
If it isn't being caused by debris on the contact points then something a bit more worrying may be causing the issue. At this point, you should get in contact with the iRobot support team for further troubleshooting or arranging a professional repair.
