Roomba is an AI Robot vacuum cleaner that cleans through an advanced mapping system of your home. But, Roomba may get into minor troubleshooting errors which stop Roomba during its cleaning cycle.

When my Roomba was cleaning my room, I noticed it was giving Error 15. Upon researching, I found that Roomba Error 15 is basically an issue in the internal navigational system which was not letting my vacuum communicate with its Home Base or App.

What is Roomba Error 15

Roomba error 15 is usually due to a blockage of the iRobot app connection with Roomba which is due to nominal issues in its internal components, Network misconfiguration, or Power supply in the battery.

Causes and Fixes of Roomba Error 15


  • An internal software issue
  • Obstruction or thick wall between the Roomba and its Home Base.
  • Network error which may be due to an issue with your Wi-Fi router or low connectivity
  • Battery failure resulting in power supply gaps


  • Press Clean Once and try to restart it.
  • Check your Network and Wi-Fi router

  1. How many times will this silly thing reject my message, my name, and/or my email address? Really? Seriously?

    ERROR 15
    Ruhmi the Rhyming Roomba (i-7) stops in her tracks and reports “Error 15”
    Push start button
    No response
    Push start button
    Push start button
    Return Ruhmi to her home base.
    Three second pause, then “Ping!” as though she has done something magical, if not truly miraculous.
    Then swirling white ring appears as if in celebration.

    After leaving on station for an hour or to, she will resume normal duties.
