Error thirty-six (36) means that the bin full sensors for your Roomba i series robot were not cleared when the robot evacuated debris into the Clean Base®. You may also see a red light sweeping towards the rear of the robot.
Ensure that the sensors on the robot cleaning head and bin have been cleaned off:
- Remove the filter from the bin
- Rinse the bin and bin door with water, then let them air dry
- Wipe the bin full sensors on the robot with a clean, dry microfibre or soft cotton cloth
- Remove the brushes and ensure the vacuum path is clear of debris
Note: Scrub the vacuum path with a magic eraser to clean out any built up dirt or grime that has accumulated.
If you have a Clean Base™, follow these maintenance steps to make sure there is no clog in the dock itself. If the robot can't properly evacuate, the bin will remain full and trigger error 36.
If the error persists, please reboot the robot by pressing and holding the CLEAN button for 20 seconds.
