Error 2
iRobot Error 2 on Roomba: rubber brushes cannot turn
Risk level
Low
Usually safe to check without specialist tools.
Urgency
Low
Quick answer
Roomba says Error 2: the multi-surface rubber brushes cannot turn. Remove them, clear hair under the end caps and first test the robot without brushes to learn whether the fault is in the brushes or in the cleaning head.
Safety first
Stop and check this first
- Switch the robot off before putting your fingers in the cleaning head, and do not cut the rubber brushes with blades when removing wrapped hair.

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.
Warranty review
What they doiRobot Customer Care reviews the case with the robot charged, the serial number and the invoice from an authorized retailer.
They must show youthe case number and what they checked.
In writingwhether it is covered and what is repaired or replaced.
Cleaning head inspection
What they doIf the error persists without brushes, iRobot or its authorized service checks the cleaning head module and its motor.
They must show youthe fault reproduced without brushes and the module check.
In writingthe diagnosis, the replaced part with its reference and a cleaning test afterwards.

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.

Test on a hard floor
No special tools
Procedure
- Who:
- you.
- How:
- if the error appeared on carpet, take the robot to a hard floor and press CLEAN, as iRobot suggests.
- Result that matters:
- whether Error 2 also appears on a hard floor.
- If it does not appear on a hard floor:
- the rug is slowing the brushes; exclude it from the map.
- If it appears anyway:
- continue with the test without brushes.
- Evidence to keep:
- a note of the floor type where the error appeared.

Test without brushes
No special tools
Procedure
- Who:
- you.
- How:
- open the Cleaning Head Module door by pushing the green tab on the right side of the brushes, remove them, close the door, place the robot on a flat floor and press CLEAN.
- Result that matters:
- whether the robot runs without brushes and without Error 2.
- If it runs without brushes:
- the problem is in the brushes; clean them.
- If Error 2 persists without brushes:
- the brushes are ruled out; contact iRobot.
- Evidence to keep:
- a short video of the test without brushes and the serial number.

Clean the brushes and end caps
No special tools
Procedure
- Who:
- you.
- How:
- remove hair and debris from the brushes, especially under the end caps, refit them and test on a flat floor. iRobot recommends cleaning them at least once per week.
- Result that matters:
- whether the robot keeps running without the error with the brushes fitted.
- If it no longer appears:
- it was built up debris; keep the weekly cleaning.
- If it returns with clean brushes:
- they may need replacing.
- Evidence to keep:
- a photo of what was under the end caps and the cleaning date.

What it means
In the i Series chart, Error 2 means the multi-surface rubber brushes cannot spin. The robot senses it through the load on the cleaning head motor. The usual cause is hair or debris wrapped under the end caps, but iRobot notes that thick carpet or high-pile rugs can also slow the brushes too much. The test without brushes that iRobot describes separates the brushes from the cleaning head module; the code alone does not show that the cleaning head is faulty.
Warnings and stop conditions
- Loweditorial warning
Switch the robot off before putting your fingers in the cleaning head, and do not cut the rubber brushes with blades when removing wrapped hair.
