1. Try another power outlet

If your Roomba doesn’t seem to be charging, it could be the power outlet that is faulty and not the device itself. It sounds simple enough but it is something that you might have failed to check if your Roomba not charging.

Sometimes the simplest option is the one that you need to take so you should try this before even trying anything else. If you don’t see the power lights flashing on the device when it is plugged in, it is likely that the power outlet has tripped.

Try plugging it in somewhere else in your home and also make sure that the connection is pushed in tightly and see if that works.

2. Clean the electrical contact points

Even though the Roomba itself will clean without you doing any of the work, you still need to give the device some TLC from time to time to make sure that it is working and performing to its best.

The electrical contacts are known to form an oxide layer regularly, which means that dust and other debris can form on the charging port. It is really easy to clean the contact points though and all you need to do is use a clean microfiber cloth and some rubbing alcohol on the affected areas.

Do this every few days to make sure that your Roomba is charging the way that it should be! If you don’t have to rub alcohol, a magic eraser will also do the trick. Both these ingredients will clean the contact points without doing any damage.

Expert Tip: Make sure that you unplug the home base before you clean the contact points to avoid electric shocks.

3. Clean the docking station

If there is not a sufficient power supply going into your Roomba, this could be one of the reasons why it is not charging correctly. If dust has accumulated in the charging station, it could be stopping a connection between the ports and outlets. You can clean the docking station by following these steps.

  • Turn the Roomba over and take it off the docking wheel.
  • Make sure that the wheel itself is clear of debris.
  • Use rubbing alcohol and a cloth to clean the docking station and associated outlets.

4. Reposition the battery or reset your Roomba
