Roborock Carpet Detection Failure

Robot vacuum does not detect carpets properly (fails to boost suction or lift mop on carpets).

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Ultrasonic carpet sensor dirty or faulty, Carpet detection disabled in app, Carpet color or material confusing sensors, Firmware bug

Safety first: Turn off the robot and place it upside down.

Step-by-step:

Enable carpet mode: In the Roborock app, ensure carpet boost and mop lift on carpet are enabled.
Clean sensors: Wipe underside ultrasonic or optical carpet sensors with a soft cloth.
Update firmware: Install any available firmware updates.

If carpets are still not detected and other functions work, the carpet sensor module may be defective and require replacement.
