Robots have come a long way since being clunky, slow-moving boxes. We have advanced robots driving our cars, running our factories and cleaning our homes.

In this article, we’re talking about Roomba error 15, its causes and what you can do to get your robot vacuum up and running.

What causes Roomba error 15?

Depending on your Roomba model, error 15 can mean either a battery failure or an internal issue. Several reasons can trigger Roomba error 15, and it’s not always bad. The robot is just telling you it faced a problem and took care of it by itself. However, if error 15 is coming up on every clean job, you have a problem.

It’s also essential that users don’t confuse this with charging error 15. For Roomba I and J series, charging error 15 indicates a cell failure during charging, and the battery will need to be replaced before the robot can function again.

How to fix Roomba error 15?

Here are seven solutions you can try to fix Roomba error 15.

Restart the cleaning process

As mentioned before, error 15 isn’t always about something wrong. Some Roomba models require a cleaning process restart after encountering error 15. You have to press the Clean button on the robot, give it a little time to reorient itself, and you’re good to go.

Check your WiFi

Roomba uses your house’s WiFi to connect to the phone app and base station. If your WiFi is down or not working, it can cause problems with the robot. Check if your WiFi network is active, has internet access and that your Roomba is within range of your router.

Reconnect Roomba to WiFi

Error 15 on your Roomba can also be solved by reconnecting it to your home WiFi network. However, you’re first going to have to get your Roomba off your home WiFi.

To disconnect your Roomba from the WiFi, hold down the Home, Clean and Spot Clean buttons at the same time until you hear a beep. Once disconnected, head over to the iRobot app, connect to your Roomba using Bluetooth and reconnect to your home WiFi.

Revert the smart map of your house

Another thing that you can do to get rid of the error is to revert your house’s Smart Map to a previous version. Head over to the iRobot app, access the history and use any of your clean map reports to revert your Smart Map.

If that doesn’t work, you can also remap your house by deleting all existing Smart Maps and creating a new one. This will help the robot get used to anything that might be differently placed.

Restart your Roomba

Restarting a device to fix temporary errors is a relatively common solution for any electronic device. Here’s how. 

For S and I series models

Hold the Clean button for around 20 seconds until the white LED ring around the bin’s lid starts spinning clockwise. Wait for the Roomba to turn back on and see if the issue persists. 

For the 700, 800 and 900 series 

Hold down the Clean button until you hear a beep. Give the Roomba a couple of minutes to start and run the cleaning schedule again. Error 14 shouldn’t be a problem now. 

Perform a factory reset

You can also perform a factory reset on your Roomba to resolve firmware issues. Do keep in mind that you’ll need to have the robot paired with your phone and the iRobot app installed for this to work. 

You have to head over to the in-app settings and select factory reset. After this, the robot will automatically reinstall its firmware, eliminating any firmware issues in the process. 

Contact support

If nothing else works, your best option is to contact iRobot support and possibly send the robot in for repairs.
