Roborock Robot Vacuum Error Code 15: How to Fix It

Q: How often should I clean the wall sensor on my Roborock vacuum?

Clean the wall sensor every 2-3 weeks or whenever you notice navigation issues. Homes with pets or high dust levels may require more frequent cleaning.

Q: Can I use water to clean the Roborock wall sensor?

No, never use water or liquid cleaners on the wall sensor. Use only a dry microfiber cloth or slightly damp cloth that's been wrung out completely. Moisture can damage the electronic components.

Q: Why does my Roborock keep getting Error Code 15 even after cleaning?

If Error Code 15 persists after cleaning, the sensor may be damaged, the bumper assembly could be misaligned, or there may be an internal wiring issue. Contact Roborock support for further assistance.

Q: Will Error Code 15 prevent my Roborock from cleaning?

Yes, Error Code 15 will typically stop the cleaning cycle because the vacuum cannot navigate safely without a functioning wall sensor. The robot needs this sensor to avoid collisions and map your home properly.

Abstract

Roborock Error Code 15 indicates that your robot vacuum's wall sensor is dirty and needs cleaning. This sensor helps the robot navigate around walls and furniture, so when it's blocked by dust, hair, or debris, the vacuum can't function properly.
