Roborock Robot Vacuum Error 11 — Magnetic strip / no-go interference

Roborock Robot Vacuum · Error code Error 11

What Error 11 Means

The robot detected a strong magnetic field (a virtual wall strip, or other magnet). It stops because it thinks it's at a boundary.

Symptoms

  • Voice prompt 'Strong magnetic field detected'
  • App shows Error 11
  • Robot stops near appliance or strip

Common Causes

1
Magnetic boundary strip in path

Roborock-brand or third-party magnetic strip is too close.

2
Strong magnet near robot

Speaker, motor, or magnetic items on the floor.

3
Robot starts run on/over a magnetic strip

Initial location is inside a boundary it can't escape.

How to Fix It

  1. Move the robot at least 3 feet away from any magnetic strip or magnet.
  2. Verify the dock is not placed near a magnetic boundary strip.
  3. Use virtual no-go zones in the app instead of physical magnetic strips on newer LDS models.
  4. Restart cleaning.
