If your Roborock won't return to its dock, check the power and clear the route first. Then clean the dock's signal window and the robot's front sensor. Moving the robot during a job can also make it lose its position. If it reaches the dock but won't charge, check the charging contacts instead.
Try this first
- Check the power cable. Make sure it's firmly connected at the dock and wall. Try a known working outlet if the dock seems unpowered.
- Clear the approach. Move shoes, cables, and furniture out of the robot's path. Follow your dock manual for clearance; Roborock's general guide calls for 0.5 m on each side and 1.5 m in front.
- Clean the signal areas. Wipe the dock's front signal window and the robot's front sensor as directed in the manual.
- Start a fresh test from the dock. Let the robot begin there, then use its return command. Avoid picking it up during the test.
It gets lost before reaching the dock
Think about what changed: a moved dock, a closed door, a different floor, or a robot carried into another room. Restore a clear route and let it start from the dock again.
If your model uses saved maps, check that you're using the right floor map. Try the simple checks before deleting it; rebuilding a map also means setting up any room divisions and restricted areas again.
It reaches the dock but won't charge
Check the charging contacts on the robot and dock. Unplug the dock before cleaning, and use the method in your model's manual. Let any cleaned surfaces dry before reconnecting.
Then place the robot on the dock and check for its charging message or indicator. If there's an error, save the exact wording. A charging failure doesn't by itself prove that the battery needs replacing.
Still stuck?
Contact Roborock with the robot and dock model numbers, error message, and a short video of the failed attempt. Say whether it gets lost, approaches but can't line up, or docks without charging. That distinction is more useful than “it won't dock.”
