Error 11 Moderate Easy DIY

iRobot Robot Vacuum Error 11 — Bin full or airflow blocked

iRobot Robot Vacuum · Error code Error 11

What Error 11 Means

Bin sensors detect the dustbin is full or airflow is severely restricted.

Symptoms

  • 'Error 11' or 'empty Roomba's bin' voice prompt
  • Cleans for very short time before stopping
  • Reduced suction

Common Causes

1
Bin actually full

Self-explanatory — empty it.

2
Dirty bin sensor windows

IR sensors that detect bin fill level are covered in dust.

3
Clogged filter

Restricted airflow simulates a full bin to the sensor.

How to Fix It

  1. Empty the dustbin completely.
  2. Locate the two small clear sensor windows on the inside top corners of the bin cavity (on the robot, not the bin).
  3. Wipe these windows with a clean, dry microfiber cloth.
  4. Tap or wash the filter (model-dependent — only certain filters are washable).
  5. Reinstall and test.
