Why Cleaning Roborock Sensors is Important

The sensors on your Roborock are crucial for its navigation and cleaning capabilities. Dirty sensors can lead to issues such as:

• Inaccurate navigation: The vacuum may not map rooms correctly or might get stuck more often.
• Reduced obstacle detection: The robot may bump into furniture or miss objects on the floor.
• Faulty drop detection: The vacuum may not detect stairs or ledges, increasing the risk of falls.
• Reduced cleaning efficiency: The Roborock may not follow its optimal cleaning path, leading to incomplete or inefficient cleaning.

Regularly cleaning the sensors ensures your Roborock continues to perform at its peak, providing thorough and efficient cleaning throughout your home.

Tools Needed for Cleaning Roborock Sensors

Before starting, gather the following tools to clean your Roborock’s sensors:

1. Microfiber cloth: A soft, lint-free cloth for wiping the sensors.
2. Cotton swabs: For reaching small areas and cleaning delicate components.
3. Isopropyl alcohol (70% or higher): For removing stubborn dirt and debris (use sparingly).
4. Compressed air (optional): For blowing dust out of hard-to-reach places.

Now that you have everything you need, let’s get started!

Step-by-Step Guide: How to Clean Roborock Sensors

Step 1: Turn Off and Unplug the Roborock

Before cleaning your Roborock, turn it off and unplug it from the charging dock. This will prevent any accidental damage or activation during the cleaning process.

1. Press and hold the power button until the device turns off.
2. If the Roborock is charging, remove it from the charging dock.

Step 2: Identify the Location of the Sensors

Roborock vacuums are equipped with various sensors located in different parts of the device. Depending on the model, these sensors may include:

• Cliff sensors: Located underneath the vacuum, these detect ledges and stairs to prevent falls.
• Wall sensor: Typically located on the right side, it helps the vacuum follow walls closely.
• Obstacle detection sensors: Found on the front bumper, these sensors help the Roborock avoid obstacles.
• Charging contacts: Metal plates located at the base, ensuring proper connection with the charging dock.
• LiDAR or camera sensors: Found on top of models with advanced navigation (e.g., Roborock S6, S7, or MaxV series).

Consult your user manual to locate all the sensors specific to your Roborock model.

Step 3: Clean the Cliff Sensors

The cliff sensors are crucial for preventing your Roborock from falling off stairs or ledges. To clean them:

1. Flip the Roborock upside down to access the bottom.
2. Use a dry microfiber cloth to gently wipe each cliff sensor.
3. If dirt is stubborn, lightly dampen the cloth with isopropyl alcohol and wipe again.

Ensure the sensors are completely dry before turning the Roborock back on.

Step 4: Clean the Wall Sensor

The wall sensor is usually located on the right side of the vacuum and helps it maintain a consistent distance from walls. Here’s how to clean it:

1. Use a dry microfiber cloth or a cotton swab to wipe the wall sensor gently.
2. Avoid using too much pressure, as the sensor is delicate.
3. If needed, use a slightly dampened cotton swab with isopropyl alcohol to remove any tough grime.

Step 5: Clean the Front Bumper Sensors

The front bumper sensors detect obstacles and help the vacuum navigate around them. To clean these sensors:

1. Locate the small sensors behind the front bumper.
2. Use a dry cotton swab or microfiber cloth to carefully wipe each sensor.
3. If there’s a buildup of dust or dirt, use compressed air to blow it away gently.

Step 6: Clean the LiDAR or Camera Sensor

For Roborock models equipped with a LiDAR sensor or camera-based navigation system (e.g., S6, S7, or MaxV series), it’s important to keep these components clean for accurate mapping.

1. Gently wipe the LiDAR or camera sensor with a dry microfiber cloth.
2. Use a slightly dampened cloth with isopropyl alcohol if needed, but avoid using excessive liquid.
3. Be gentle when cleaning the LiDAR unit or camera, as these components are sensitive and can be easily damaged.

Step 7: Clean the Charging Contacts

Clean charging contacts ensure your Roborock can recharge properly. To clean the charging contacts:

1. Locate the metal contacts at the base of the Roborock.
2. Use a dry microfiber cloth to wipe away dust and dirt.
3. Avoid using any liquid cleaners on the contacts.

Step 8: Final Inspection and Testing

Once you’ve cleaned all the sensors, inspect each one to ensure they are free of dirt and debris. Afterward, turn the Roborock back on and test it to confirm that all sensors are functioning correctly. Observe its behavior as it navigates around your home—if it seems to operate smoothly and without issues, the cleaning was successful!

How Often Should You Clean Roborock Sensors?

To keep your Roborock operating at its best, it’s recommended to clean the sensors at least once a month. However, if you have pets or your home tends to accumulate dust quickly, consider cleaning them more frequently, such as every two weeks. Regular maintenance will help prevent navigation issues and ensure your Roborock continues to clean efficiently.

Troubleshooting Common Sensor Issues

If you notice any of the following issues even after cleaning the sensors, you may need to perform additional troubleshooting:

• Robot vacuums stop unexpectedly: Check the cliff sensors again and ensure they are free of dirt. In some cases, dirt or hair can get trapped in the sensor openings, causing false signals.
• Robot cannot find its charging dock: Ensure the charging contacts are clean and the dock is placed in an open, accessible area.
• Roborock is bumping into furniture: Check the obstacle detection sensors on the front bumper and make sure there is no dirt obstructing them.

If the issues persist, refer to your Roborock’s user manual or contact customer support for further assistance.

Final Thoughts

Keeping your Roborock’s sensors clean is a simple yet essential part of maintaining your robotic vacuum. By following these step-by-step instructions, you can ensure that your Roborock continues to perform at its best, providing efficient and thorough cleaning throughout your home.
