Has your Roborock’s main brush stopped spinning, leaving your floors less than sparkling clean? You’re not alone. Many Roborock users face this issue, which can be a real headache, especially if you’re relying on your Roborock to keep your home tidy. But don’t worry! We’ve created this practical, step-by-step guide to troubleshoot and fix your Roborock main brush not spinning. Let’s bring your Roborock back to its top-notch performance!

Roborock Main Brush Not Spinning: Common Causes

Brush blockage

One of the most frequent causes of the Roborock main brush not spinning is brush blockage. Debris, hair, or dust can accumulate on the brush, causing it to be obstructed and preventing it from spinning effectively. This is especially common if your Roborock is regularly used to clean pet hair or in high-traffic areas where larger debris may be present.

Motor failure

Another common cause of the Roborock main brush not spinning can be a motor failure. Often due to wear and tear, the motor that drives the main brush can fail, preventing the brush from spinning. While this is less common than a blockage, it’s still a possibility that should be considered.

Software glitches

Software glitches are another possible reason for your Roborock main brush not spinning. Unexpected bugs or malfunctions in the software can interfere with the operation of the main brush. It’s not always obvious when a software glitch is the cause, but there are a few signs you can look for.

Typically, if your Roborock is behaving erratically or not responding to commands in the usual way, it might indicate an underlying software issue. If you’re noticing such behavior alongside the main brush not spinning, a software glitch could well be the culprit.

Step-by-Step Troubleshooting Guide For Roborock Main Brush Not Spinning

How do you clean a Roborock brush

  1. Inspect the main brush: The first step in checking for brush blockages involves unplugging your Roborock and flipping it over to expose the main brush. Look for visible signs of debris or blockages.
  2. Remove the main brush: Next, carefully remove the main brush by lifting it from its holder. Ensure you handle it gently to avoid causing damage to the bristles or the brush housing.
  3. Clean the main brush: Once the brush is released, inspect it for any tangled hair or debris lodged in its bristles. Use a pair of scissors or brush cleaning tool to cut and remove any obstructions you come across.
  4. Reinstall the main brush: After you have thoroughly cleaned the brush, place it back in its holder. Make sure it fits snugly and spins freely before flipping the Roborock back over.
  5. Test the Roborock: Finally, plug the Roborock back in and run a cleaning cycle. Watch to see if the main brush spins as expected. If it’s still not spinning, proceed to the next step of the troubleshooting guide.

Maintenance or cleaning of the main brush is often overlooked, but it’s crucial to ensure optimal performance. Regular inspection and cleaning of the brush can avoid such blockages and ensure your Roborock continues to provide you with thorough, efficient cleaning.

If you notice that your Roborock’s main brush is not spinning, the first thing you should do is check for any visible blockages on the brush. Remove the main brush and inspect it carefully. If you find any hair, string, or other debris wound around the brush, it may be the culprit. Remove the debris and reinstall the brush, then run a cleaning cycle to see if the problem persists.

Testing the motor

  1. Switch off the Roborock: The first step in testing the motor involves switching off your Roborock. This is important to ensure safety while you’re carrying out the following steps.
  2. Manually spin the brush: Next, manually spin the brush. You can do this by flipping the Roborock over and gently pushing the brush with your hand. If the brush spins freely with minimal resistance, this could indicate that the motor is failing.
  3. Listen for sounds: While you’re spinning the brush, listen for any abnormal sounds. If you hear grinding or whirring noises, this might suggest an issue with the motor.
  4. Check for heating: Finally, run a cleaning cycle while observing the area around the brush. If you notice that the motor area is heating up excessively, this can also be a sign of motor failure.

By following these steps, you can get a better idea if the motor is the cause of your Roborock’s main brush not spinning.

However, diagnosing and fixing a motor failure requires technical skills and may void your warranty. If you suspect that the motor is the issue, it’s recommended to contact Roborock’s customer service or a professional repair service. Remember, attempting to repair the motor on your own can lead to further complications if not handled properly.

Resetting the software

  1. Try a simple restart: The first step to addressing potential software glitches is to try a simple restart of your Roborock. Unexpected bugs or malfunctions can often be cleared through a restart, helping your device return to its normal operations.
  2. Perform a factory reset: If the simple restart doesn’t work, you might need to consider a factory reset. This step restores your Roborock to its initial settings, which can often resolve more complex software issues. However, keep in mind that this step will erase all your custom settings and cleaning schedules.
  3. Update the software: Lastly, ensure that your Roborock’s software is up-to-date. Roborock frequently releases software updates to fix bugs and improve the device’s performance. Updates can be checked for and downloaded through the Roborock app.

Following these steps will help you to troubleshoot potential software issues that might be causing your Roborock’s main brush to stop spinning. If the problem persists, don’t hesitate to reach out to Roborock’s customer service for further assistance.
