What are the common sensor malfunctions of the Xiaomi Robot Vacuum?
The Xiaomi Robot Vacuum shows irregular cleaning paths, fails to recognize surroundings, or stops unexpectedly due to dirty sensors, poor lighting, or component faults.
The most commonly affected sensors include:
1. Carpet sensor (ultrasonic): Detects carpets to switch between sweeping and mopping modes.
2. Floor detection sensor: Prevents the robot vacuum from falling off edges.
3. Obstacle avoidance sensor: Identifies objects in front of the robot vacuum.
4. Water tank detection sensor: Checks whether the water tank is installed.
5. Dust compartment detection sensor: Monitors the presence of the dust compartment.
6. Drive wheel position sensor: Detects wheel motion and positioning.
7. Infrared radar sensor (LDS/PSD): Measures distance and supports navigation mapping.
When these sensors malfunction, the robot vacuum will clean aimlessly, circle repeatedly, misjudge terrain, or move along open spaces.
For your reference, please follow the steps to troubleshoot:
Carpet sensor:
1. Check the bottom and front of the robot vacuum for dust, dirt, or water stains that block the ultrasonic signal.
2. Gently wipe the carpet sensor area with a dry, soft cloth.
3. Restart the device and test whether it can correctly identify carpeted areas.
Other sensors:
1. Ensure all sensor windows and the top radar module are clean and unobstructed.
2. Wipe the infrared radar, cliff sensors, and obstacle detection lenses with a dry cloth.
3. Test the robot vacuum in a well-lit, open area to confirm normal navigation.
4. If the issue persists after cleaning, contact the office after-sales service center for further inspection.
Friendly tips:
Regularly cleaning all sensor windows helps maintain accurate detection and stable navigation performance.
