Error 11
Roborock Error 11 on robot vacuum: magnetic field detected
Risk level
Low
Usually safe to check without specialist tools.
Urgency
Low
Quick answer
Roborock shows Error 11, strong magnetic field detected: the robot is too close to barrier tape at startup. Move it away from the magnetic barrier tape and restart; consider app no-go zones instead of tape near the start point.
Safety first
Stop and check this first
- The manual says no-go zones and barrier lines should only be used to set cleaning areas, not to isolate hazardous areas such as stairs or drops.
Safe checks you can perform
- Move away from the barrier tape
- Check the tape around the dock
- Use app no-go zones instead

These are not instructions for opening or handling the equipment yourself. They are the checks that should support a technical conclusion.
Case review by Roborock after-sales
What they doRoborock after-sales service reviews the case after you have done the manual's steps and a system reset.
They must show youthe case number and their diagnosis.

Sensor diagnosis by authorized service
What they doRoborock's authorized service checks the robot's sensors with the unit opened and powered off, if Error 11 appears with no magnet nearby.
They must show youthe error reproduced away from any tape.

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.
- 1
Move away from the barrier tape
No special tools
Procedure
- Who:
- you.
- How:
- move the main unit away from the barrier tape and restart it, as the manual says.
- Result that matters:
- whether it starts without Error 11.
- If it starts:
- proximity to the tape at startup was the cause.
- If it repeats away from any tape:
- reset the system.
- Evidence to keep:
- a photo of where the robot and tape were.

Check the tape around the dock
No special tools
Procedure
- Who:
- you.
- How:
- look for barrier tape near the charging dock or in the area in front of it, which the manual asks you to keep clear for at least 1.5 m.
- Result that matters:
- whether a strip sits where the robot starts its runs.
- If it does:
- move the strip or the dock; that explains the repeat.
- If not:
- try a system reset.
- Evidence to keep:
- a photo of the dock area.

Use app no-go zones instead
No special tools
Procedure
- Who:
- you.
- How:
- with map saving on, set virtual no-go zones or barrier lines in the app for the area the tape was protecting, and remove tape from the start area.
- Result that matters:
- whether the robot starts and respects the virtual zone.
- If it does:
- keep the virtual zones; the manual notes moving the robot or changing the home can lose saved zones.
- If Error 11 continues with no tape nearby:
- reset the system and contact after-sales.
- Evidence to keep:
- a screenshot of the zones.

What it means
In the Roborock S6 manual, Error 11 means a strong magnetic field was detected because the main unit is too close to a barrier tape at startup. The robot senses magnetic barrier tape to avoid crossing it, and if it starts right next to or on top of a strip it cannot begin its run. The code does not prove a sensor fault: the manual's fix is to move the robot and restart. If no tape or magnet is near the start position and it persists after a reset, Roborock after-sales should review it.

Symptoms and causes
Probable causes · in order
- Started next to barrier tapeCommon
The robot was placed on or beside a magnetic strip and starts normally a short distance away.
Evidence: Roborock S6 Robotic Vacuum Cleaner Manual
- Charging dock close to the tapePossible
It happens every time it leaves the dock because a strip runs near the dock, which is where it starts.
Evidence: Roborock S6 Robotic Vacuum Cleaner Manual
- No tape nearbyLess common
It persists with no barrier tape near the start point and after a system reset, so after-sales should check the robot.
