Troubleshooting guide
How to fix the problem
Roborock S5 Error 1 is related to the laser navigation unit. First check that it is not covered by an object or visible dirt. Do not apply the explanation of this number to another brand of robot.
Possible solutions
Choose the method that matches your situation. Start with the simplest suitable option and check the result. If the problem is fixed, you do not need to continue with the other methods.
External inspection of the S5 laser
Avoid breaking and strong pressure.
Steps to follow
- Turn off the robot, examine the upper turret and remove the items left on it.
- Wipe the accessible outside of the window with a soft, dry cloth.
- Check that the turret is not being pressed by furniture or an inappropriate body accessory.
- Turn on in a free space and watch one start without touching the moving block.
Applying the official Error 1 instruction
Follow the manufacturer's steps specifically for the S5.
Steps to follow
- Open the official explanation of Roborock Error 1 and check the model.
- If the instruction provides for a soft user check, perform only the permitted action; do not twist the knot by force.
- Perform a normal reboot of the bot and check if the error recurs.
- If the unit does not move or there is an unusual sound, stop and ask for repairs without erasing the map just by guessing.
Features, menus and error codes depend on the exact robot and dock model and software version. Instructions for another series may not apply.
If the problem persists
If the laser unit does not start working or the error returns after authorized maintenance, its motor and electronics need to be checked. The advice of the forum to change the motor without diagnostics does not confirm that it is the one that is faulty.
Request a repairBefore you begin: Before maintenance, stop and switch off the robot and unplug the dock. Do not touch moving parts during operation. If liquid reaches electrical components or the battery is damaged, do not power the device on again until it has been inspected.
