What to do if Roomba is not charging?

If there are no lights on the Roomba showing that it is charging and there are no indications on the Home App as well, the following steps should be taken to ensure that the Roomba starts charging

  1. Check the cord of the Home Base for any damages. 
  2. Try charging in a different electrical outlet. 
  3. Check the charging contacts of both the Roomba and the Home Base. If there is dust and fluff build-up on the charging contacts, clean them properly. This dust might be obstructing the flow of charge. 
  4. Check the caster wheel of your Roomba for any debris, fluff, or hair stuck in there. If there is a debris build-up in the caster wheel, Roomba will not be able to reach the charging contact on the Home Base. And if there is no proper contact between the Roomba and the Home Base, it will not charge.
  5. If your Roomba is producing a charging error, take notice of which charging error is indicated. Then consult the charging error message chart. 
  6. You can also reboot your Roomba. Rebooting a Roomba will, sometimes, resolve the charging issues. 
  7. If after doing everything you can, the Roomba not charging problem still persists, you should contact iRobot customer care
