What Does Roborock Error 2 Mean and How Do I Fix a Stuck Bumper?
- The front bumper is physically stuck pressed in
- Debris or hair is wedged behind the bumper
- The robot started wedged against furniture
Problem Description
Your Roborock is reporting Error 2, which means the front bumper is stuck or has debris jammed behind it. The robot reads the pressed-in bumper as a constant collision and stops, but this is almost always a quick mechanical fix rather than a fault.
Why This Happens in Real Homes
Roborock Error 2 points squarely at the front bumper: the robot reads a bumper stuck in the pressed position as a permanent collision and refuses to drive. In practice it is almost always debris or pet hair packed into the gap behind the bumper, or the robot having started wedged against furniture or a cord. Tap the bumper in and out to confirm it springs back, clear the seam all the way around, move the robot onto open floor, and restart. Only if the error returns with a clean, freely-moving bumper is the sensor itself likely at fault, which is a support case with your model and error number.
Symptoms
- The robot announces Error 2
- It will not move forward
- It stops and reports a collision
- The front bumper feels stuck or pressed in
- It behaves as if it is always hitting something
- It will not leave the dock
- The error appears after cleaning near furniture
- The bumper does not spring back on its own
Recognize these? Here's what usually causes it.
Common Causes
- The front bumper is physically stuck pressed in
- Debris or hair is wedged behind the bumper
- The robot started wedged against furniture
- Pet hair packed into the bumper's pivot points
- A small object is trapped in the bumper gap
- The bumper sensor is stuck
- The robot stopped hard against an obstacle
- A damaged bumper spring
Most fixes happen in the first 3 steps.
This is a routine cleaning fix with no safety risk. Power the robot off before clearing anything jammed in the bumper, and do not force a bumper that will not move - contact Roborock instead.

Step-by-Step Solution
Tap the bumper
Press the wide front bumper panel in and out several times - it should spring back freely each time. Error 2 means it is stuck pressed in, so the robot believes it is constantly hitting something.
Clear debris behind the bumper
Dust, hair, or a small object wedged in the gap between the bumper and the body holds it depressed. Wipe along the seam all the way around and work out anything trapped in the gap.
Move it to open floor
If the robot started or stopped wedged against furniture, a rug edge, or a cord, the bumper is held in. Place it in the middle of the room on a flat surface, then restart.
Clean hair from the pivots
Fine pet hair packs into the bumper's pivot points and stops it moving. Clean those points so the bumper travels smoothly in and out.
Still stuck? Ask Trunetto about this exact issue.
Restart the robot
Power the robot off and on, or restart it from the app, after freeing the bumper so it clears the Error 2 state and re-checks the bumper.
Check it springs back
After cleaning, confirm the bumper returns on its own when you press and release it. If it stays in, a spring or the bumper itself may be damaged.
Prevent it happening again
Keep the robot's start area clear of thin cords and low obstacles the bumper can wedge under, and add no-go zones for spots where it repeatedly gets stuck.
Contact support if it persists
If Error 2 returns immediately with a clean, freely-moving bumper, the bumper sensor may be faulty. Contact Roborock support with your model name and the error number.

Still having issues? This is usually the deeper cause below.
If this comes back after following these steps, check whether a recent app or firmware update reset a default setting — the fix works, but the setting gets reverted silently.

List Your BusinessError 2 is nearly always a stuck bumper, not a broken sensor - the quickest fix is to tap the bumper in and out a few times and clear the hair and debris packed into the gap behind it so it can spring back freely.
This issue almost always looks more complex than it is — the majority of cases trace back to a single setting, a stale credential, or a default that shipped wrong.
