Roborock Robot Vacuum Error 2 — What It Means & How to Fix It
Roborock Error 2 means the front bumper is stuck in its pressed position.
What this code means
The Q5 manual's wording is "Bumper stuck. Clean it and lightly tap to release it." The bumper is the sprung front section that tells the robot it has touched something. Grit behind it can hold it in, and the robot then stops because it reads a collision that never ends.
Taken from the Errors table in Roborock's Q5 user manual. Roborock reuses these low numbers across many models, but the lists are not identical — higher numbers in particular differ — so check the manual for your robot.
Most likely causes
| Cause | How likely | DIY-fixable? |
|---|---|---|
| Dirt or small debris lodged behind the bumper | Very common | Yes — no tools |
| Robot jammed against an obstacle | Common | Yes — no tools |
What you can try yourself
- Pull the robot away from whatever it was touching.
- Tap lightly along the bumper to release it.
- Wipe the bumper and the gap around it to remove dirt.
- Put the robot down somewhere clear and restart cleaning.
When to call a technician
- The bumper stays pushed in on one side.
- Error 2 appears with the bumper moving freely.
Typical professional repair cost: Free. If the bumper is damaged, contact Roborock customer service.
