Roomba Error 15: Causes and Solutions

Whether you have a Roomba 675, i6+, j7, or anything in between, you probably depend on it quite a bit for your vacuuming needs. So, when you encounter a Roomba Error 15, it’s natural to be a little concerned – you don’t want to go back to vacuuming yourself! The good news is that it’s often not a major issue. This error typically indicates a minor hiccup related to the robot’s internal communication, and often resolves itself. But if you’re seeing it during every cleaning job and it’s getting in the way of your vacuuming routine, then you may need to do some troubleshooting.


In this guide, we’ll explore the common causes behind Roomba Error 15 and how to troubleshoot and resolve them.


What Is Roomba Error 15?


If you’re seeing “Error 15,” on your Roomba, it’s usually just telling you that it has experienced a minor internal issue, and has already taken care of it – it requires no intervention on your part. It’s like your robot is giving you a friendly heads-up by saying, “Don’t worry; I’ve got this.”


What Causes Roomba Error 15?


Roomba Error 15 may pop up in all kinds of situations, such as:


  • If you remove and then reinsert the battery in your robot
  • It experienced a temporary glitch
  • It has disconnected from the cloud
  • There’s a problem with its stored map


While some of these situations are expected (like when you’re removing and reinserting the battery), others may pop up and cause issues with your cleaning routine. In those cases, you’ll want to do some troubleshooting to help clear the error.


How to Fix Roomba Error 15


If Error 15 isn’t resolving itself and making it difficult to use your Roomba, try the following to get things working again:


Step 1: Reboot Your Roomba


Sometimes, all it takes is a quick reboot to get things back on track.


  • Roomba 500 and 600: For 10 seconds, press the SPOT, CLEAN, and DOCK buttons at the same time
  • Roomba 700, 800, and 900: Press the CLEAN button for 10 seconds, and listen for the reboot sound when you release it
  • Roomba i and s: For 20 seconds, press the CLEAN button, and look for the white light ring when you let go


Step 2: Remove and Reinstall the Battery


If a reboot doesn’t work, you can try reinstalling the battery.


  • Remove the battery
  • Wait for ten seconds
  • Reinstall the battery and test the robot again


Step 3: Try a Previous Smart Map


Still nothing? It could be a problem with the Smart Map, so see if there’s an old one that works.


  • Look in your History to find your Clean Map reports
  • Select a map from a previous cleaning job and locate the overflow menu. It should be in the top right corner
  • Choose Update Smart Maps and test again


Step 4: Remap Your Home


If an old map doesn’t work, consider remapping your home by deleting all of your Smart Maps.


  • Find the maps you’d like to delete.
  • Hit the three horizontal dots icon
  • Select Delete Map


Step 5: Factory Reset


If all else fails and you still can’t get rid of Error 15, you can perform a full factory reset on your robot. The easiest way to do this is through the iRobot HOME App.


  • Open the app
  • Go to Settings
  • Press Factory Reset Roomba


Hopefully by now you’re good to go!


Roomba Error 15 Resolved


Roomba Error 15 is often a minor issue that your robot can handle on its own. However, sometimes you’ll need to give it some help. By following the troubleshooting steps, you can quickly clear Error 15 and have your Roomba back to its cleaning duties, ensuring your floors remain clean and inviting. Happy cleaning!
