Risk level

Usually safe to check without specialist tools.

Urgency

Medium

Quick answer

Roomba says Error 11, vacuum problem: not enough air is flowing. Clean or replace the bin filter and, if it continues, reboot the robot by holding CLEAN for about 20 seconds to clear the error from memory.

Safety first

Stop and check this first

  • Use genuine filters or ones made for your series: a badly fitting filter can let dust through toward the vacuum motor.

Safe checks you can perform

  • Clean or replace the filter
  • Reboot the robot
  • If it persists after filter and reboot

Leave these tasks to a qualified professional

  • Do not attempt this professional task: Cleaning Head Module replacement
  • Do not attempt this professional task: Warranty service

What a technician must be able to justify

A technician is coming

These are the steps they must carry out and show you. Tick them as they work: if steps are skipped, do not accept a part swap.

These are not instructions for opening or handling the equipment yourself. They are the checks that should support a technical conclusion.

  1. Cleaning Head Module replacement

    What they doiRobot or its authorized service replaces the Cleaning Head Module when the error persists with a new filter and after the reboot.

    They must show youthe error reproduced with a new filter.

    In writingthe reference of the fitted module and a suction test after the change.

  2. Warranty service

    What they doCustomer Care handles the case with the robot charged, the serial number and proof of purchase from an authorized retailer.

    They must show youthe case number.

    In writingwhether the replacement is covered by warranty.

Before accepting a part or repair

Nothing has been shown yet. Do not accept a part swap based on the code alone.

Checks and evidence, step by step

Follow the documented order. An error code identifies the affected system, but it does not prove by itself which part has failed.

  1. 1

    Clean or replace the filter

    No special tools

    Procedure

    Who:
    you.
    How:
    remove the bin filter, clean it or fit a new genuine one and run the robot again, as iRobot recommends.
    Result that matters:
    whether the robot runs without repeating Error 11.
    If it does not repeat:
    the filter was restricting the air.
    If it repeats:
    reboot the robot.
    Evidence to keep:
    the date of the filter change or cleaning.

    Evidence: Roomba® e Series and i Series: Error 11

  2. 2

    Reboot the robot

    No special tools

    Procedure

    Who:
    you.
    How:
    hold the CLEAN button for about 20 seconds; iRobot says this clears the error from the robot's memory.
    Result that matters:
    whether the error stops appearing after the reboot.
    If it stops:
    it was a stored error that had already been fixed.
    If it returns with a new filter:
    the next step is the cleaning head.
    Evidence to keep:
    a note of the reboot date and whether the error came back.

    Evidence: Roomba® e Series and i Series: Error 11

  3. 3

    If it persists after filter and reboot

    No special tools

    Procedure

    Who:
    you.
    How:
    have the robot charged, the serial number and the purchase invoice ready and contact iRobot Customer Care.
    Result that matters:
    that iRobot assesses the cleaning head with what you have already ruled out.
    If it is under warranty:
    leave the replacement to the official channel.
    If it is not:
    ask for the exact module reference before buying it.
    Evidence to keep:
    filter and reboot dates and the serial number.

    Evidence: Roomba® e Series and i Series: Error 11

What it means

The i Series chart describes Error 11 as the vacuum motor not activating, and the code page for e and i Series puts it as insufficient airflow. The robot compares how the motor runs with the air passing through the filter and cleaning head. iRobot orders the diagnosis: filter first, then a reboot to clear the stored error and, only if it persists after both, replacement of the Cleaning Head Module. The code alone does not prove that the cleaning head is faulty.
