Roborock won't return to the dock

Severity: Warning — robot roams until the battery gives out, then waits for rescue S5S6S7S8Q

DIRECT ANSWER

When a Roborock can't find home, suspect dock placement or a stale map. The dock needs 0.5 m free on each side and 1.5 m in front; if you moved it, the robot homes to the old spot.

COMMON CAUSES · RANKED

1

Dock placed without clearance MOST COMMON

Shoved between a bookshelf and a plant, the dock's signal field gets shadowed and the final approach fails. Roborock asks for 0.5 m each side, 1.5 m in front.

2

Dock moved after mapping

The robot drives to where the dock used to be, finds a wall, and wanders. The saved map still points at the old location.

3

Dust on the dock signal window or robot sensors

A thin film over the dock's transmitter window or the robot's front sensors is enough to hide the docking beacon.

4

Robot started away from the dock UNCOMMON

Carried to another room mid-run, it loses its position reference and may never route back.

5

Direct sunlight on the dock RARE

Strong sun washes out the infrared docking signal. A dock in a bright window bay works at night and fails at noon.

HOW TO FIX IT

No battery or electrical work involved in this fix.

Re-site the dock

Flat floor, back against a wall, 0.5 m clear on each side, 1.5 m clear in front, out of direct sun and away from mirrors.

Wipe the signal paths

Dry-cloth the dock's front window and pins, the robot's bumper sensors, and the lidar turret on top.

Start every clean from the dock

The robot memorizes the dock position at launch. Don't carry it mid-run — pause it and let it drive.

Rebuild the map if the dock moved

Delete the saved map in the app's map settings, place the robot on the dock, and run a full clean so it re-learns the dock location.

Power cycle and update

Robot off, dock unplugged 30 seconds, both back on — then install any pending firmware update from the app.
