Manufacturer checks in order
- If the rollers are brand new and give an error 2 immediately after installing them, run a few more missions to loosen up the brushes; the error should go away on its own.
- On thick carpet or high-pile rugs, also test Roomba on a hard floor to see whether the issue persists.
- Open the Cleaning Head Module door by pushing on the green tab on the right side of the Multi-Surface Rubber Brushes and remove them from the robot.
- Leave the brushes out and close the Cleaning Head Module door, turn the robot over, place it on a flat surface and press the button.
- If Error 2 clears, inspect the brushes and remove any hair or debris, especially under the end caps.
- If the error returns after reinstalling clean brushes, you may need replacement Multi-Surface Brushes.
Safety notes
Use the instructions for your exact robot and dock. Stop if the unit is wet, unusually hot, damaged or has a swollen battery. Contact the manufacturer; do not bypass sensors or open sealed electrical assemblies.
When to contact support
If Error 2 persists with no brushes installed, contact iRobot Customer Care.
