1. Reboot Your Roomba

Reboot your Roomba

Rebooting is a very useful and powerful method to get your Roomba working again. When your Roomba encounters an error code, it may advise you to restart the cleaning process.

Restarting will help the Roomba reconnect with its home base and try to communicate with it again. On the other hand, restarting your Roomba will remove system glitches and generic bugs that can hinder communication between devices.

Here’s how to reboot your Roomba:

  • Roomba 500 and 600 Series: For 10 seconds, press and hold the “SPOT” “CLEAN” and “DOCK” button.
  • Roomba 700, 800, and 900 Series: For 10 seconds, press and hold the “CLEAN” button on your robot. When you release the button, your Roomba will play the reboot tone.
  • Roomba i and s Series: For 20 seconds, press and hold the “CLEAN” button on your robot. The light ring will revolve clockwise in white when the button is released.

This is the most effective method to solve Roomba Error 15. I hope this simple way will help you fix the problem. If not, then proceed to the next steps.

2. Restore a previous version of your “Smart Map”

Restore an old map

If rebooting your Roomba doesn’t work, then try restoring a previous version of the map. Your iRobot Home Map’s most recent version may have encountered some issues. When this happens, no matter how many reboots you do, your Roomba will not work.

So instead, go back to the previous version of your Smart Map and, thus, your Roomba will be able to clean without any problems. To restore the Roomba Smart Map to its previous version, follow these steps:

  • Open the ‘iRobot Home app’ on your smartphone.
  • Go to the “History” section.
  • Look through the “Clean Maps” reports.
  • Choose your favorite prior map.
  • In the top-right corner, select the ‘overflow menu’.
  • And finally, choose “Update Smart Maps

I hope restoring the previous version of the map will fix the problem. If not, then move to the next steps.

Bear in mind that this method is only for those users who have a Roomba with “Smart Maps” features.

3. Delete old map and remap your house

Delete the old map

If your Roomba is still displaying “error 15” message after the restoration of the previous map, then you have to remap your house. But first you have to delete all the previous ones.

Deleting the old maps will reduce any potential glitches and bugs from your Roomba. It will also free up your device’s storage. As a result, your Roomba will be able to work properly without any glitches.

Here’s how to delete the previous version of the map:

  • Open the iRobot Home app on your smartphone.
  • Go to your maps.
  • Choose a map.
  • Select the icon with three horizontal dots.
  • Finally, select “Delete map.

You can also delete all the maps at once by resetting your device to it’s factory setting. However, keep in mind that it also deletes other vital information.

Now to remap your house, follow the bellow steps:

  • Set your Roomba to a specified room or its home base.
  • Once again, press the “CLEAN” button.
  • Let the Roomba navigate around every room by itself.
  • Once it’s completed, rename your new map.

If you are having trouble mapping your house with Roomba, don’t panic. Read this whole tutorial on Roomba mapping and do this properly. After remapping your home, I hope roomba error 15 will be fixed. Let me know in the comment box.

4. Check and reconnect your Roomba to WiFi

If your Roomba has any problem with its wifi connection, you will not be able to fix the error 15 message on your Roomba by just rebooting or resetting it. To check if your Roomba is facing any issues with wifi connectivity, log in to the router’s admin panel by typing into the web browser, which you will find on the back side of your router.

Now, check to see if the QoS service is enabled, and if so, disable it. Then make sure your firewall isn’t interfering with your Roomba’s ability to connect to your Wi-Fi.

5. Factory Reset your Roomba
