What causes this error?

Similar to a lot of other Roomba errors, there’s no specific cause behind this issue. Instead, it can be triggered by a number of things including:

  • Low battery levels or damaged battery. 
  • Interference from other electronic devices.
  • Internal communications error. 
  • Mechanical or firmware issues on the Roomba device. 

How to fix this?

Here are six things you can do to fix the problem.

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. 

Clean all sensors

Roomba error 34 can pop up if the floor tracking sensor is too dirty, causing the Roomba to lose its sense of navigation. Clean up all the sensors on your robot and restart the cleaning job to see if that fixes your problem.

Restart the cleaning process

Error 34 isn’t always about something wrong. Some Roomba models require a cleaning process restart after encountering the error. 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.

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.
