Roborock Error 11 — Strong magnetic field detected

Severity: Warning — robot won't start this close to a magnetic virtual wall S5S6
Last verified: 2026-07-05 Tools: none Time: ~2 min Difficulty: easy

DIRECT ANSWER

Error 11 means the robot detects a high-intensity magnetic field — it is sitting on or next to the magnetic barrier tape used as a virtual wall on older models. Move it away and restart.

COMMON CAUSES · RANKED

1

Robot started on top of barrier tape MOST COMMON

Starting a clean while parked on the magnetic strip blocks the robot immediately.

2

Another magnet source nearby UNCOMMON

Speaker magnets, magnetic door stops or toys against the chassis can trip the same sensor.

HOW TO FIX IT

No battery or electrical work involved in this fix.

Move the robot away

Carry it at least half a metre from the magnetic tape or any strong magnet.

Restart the clean

Press clean again from the new position.

Reroute the tape if it repeats

Lay barrier tape so the robot approaches it side-on during cleaning, never starts on top of it.
