Roomba Error 15 (100% Guaranteed Fix)

If your Roomba is displaying error 15, it indicates that the vacuum has encountered an internal communication breakdown.

Now, this can happen in many ways!

Either the Roomba has disconnected from the cloud, its stored map has corrupted, or the system encountered a temporary glitch.


However, in this guide, I will break down iRobot error 15 and explain what you have to do if this pesky error is hampering your cleaning routine.

Let’s dive in…

How to Fix Roomba Error 15

To fix Error 15 on your Roomba, start by doing a simple restart. If the problem still happens, open the iRobot Home App, go to settings, and delete the old map. Then, make a new one.


Here are the detailed guidelines:

Step 1: Reboot Your Roomba

Reboot your Roomba

This is the first step to fix this problem!

Whenever my customers called me about this issue, I always gave them the same advice I’m giving you now—Restart your Roomba.

It’s a really effective way to get your vacuum back on track and it’s great at fixing any temporary problems that might have come up.

You probably already know how to do this.

But just in case you don’t, here are the steps:

  • For Roomba 500 and 600 Series: Press and hold the “SPOT,” “CLEAN,” and “DOCK” buttons together for 10 seconds.
  • Roomba 700, 800, and 900 Series: Press and hold the “CLEAN” button on your robot for 10 seconds. When you let go of the button, your Roomba will make a reboot sound.
  • Roomba I and s Series: Press and hold the “CLEAN” button on your robot for 20 seconds. The light ring will start moving in a clockwise direction in white when you release the button.

That’s all there is to it.

Your problem should be fixed now.

Tip: Some people find that rebooting the vacuum three times in a row is more effective than doing it just once, so you might want to give that a try!

Step 2: Restore a previous version of your “Smart Map”

Restore an old map

If rebooting doesn’t work, try restoring a previous version of the map.

It’s possible that the Roomba’s most recent version encountered some issues. In that case, no matter how many reboots you do, Roomba won’t work.

Instead, go back to the previous version of your Smart Map and restore it. Your Roomba will then be able to clean without any problems

Here’s how:

  • Open the ‘iRobot Home app’ on your smartphone.
  • Go to the “History” section.
  • Check the “Clean Maps” reports.
  • Pick a previous map you like.
  • Tap the menu in the top-right corner.
  • Choose “Update Smart Maps.”

Remember, this method is only for Roomba users with “Smart Maps” features.

Step 3. Delete the old map and remap your house

Delete the old map

If your Roomba keeps showing the same “Error 15” message even after restoring the previous map, you’ll need to create a new map for your house.

But before that, delete all the old maps.

Deleting the old maps serves a couple of purposes.

It can help reduce potential issues and bugs in your Roomba, and it’ll also free up storage space, ensuring your vacuum works smoothly.

Here’s how to delete the previous map:

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

If you want to delete all maps at once, you can reset your device to its factory settings, but be aware that this action will erase other important information as well.

Now, to create a new map of your house, follow these steps:

  • Set your Roomba to a specific room or its home base.
  • Press the “CLEAN” button once more.
  • Allow the Roomba to autonomously navigate through each room.
  • Once it’s finished, give your new map a name.

If you’re having trouble mapping your house with Roomba, you can refer to our complete tutorial on Roomba mapping to learn the process thoroughly.

Step 4. Check and reconnect the Roomba to WiFi

It’s a good idea to verify if your Roomba is having Wi-Fi connection issues.

Here’s how:

First Open your web browser and type into the address bar (you can find this information on the back of your router).

Once you’re in your router’s admin panel, check if the QoS service is turned on.

If it is, turn it off.

Make sure that your firewall is not causing any issues that might prevent your Roomba from connecting to your Wi-Fi.

Step 5. Factory Reset your Roomba
