The Roborock robotic vacuum is a popular household gadget known for its efficiency and convenience. However, like all machines, it’s not immune to occasional glitches. One common issue users face is the Roborock side brush not spinning. This issue can impede cleaning performance and limit the vacuum’s ability to reach tight corners. This guide aims to provide you with a clear, concise, and practical solution to tackle this issue and ensure your Roborock vacuum is back to working at full efficiency in no time.

Roborock Side Brush Not Spinning: Common Causes

Robot Vacuum Brush Is Not Spinning

Debris Build-up

One of the most common causes of the Roborock side brush not spinning is the accumulation of debris. Over time, dust, hair, and small particles can get tangled in the brush, obstructing its motion. Cleaning the brush regularly can prevent such issues.

The brush got loose

One of the most common reasons for a non-spinning Roborock side brush is a loose brush. As your vacuum goes about its cleaning routine, it can sometimes loosen the brush attachment screw over time. This will cause the brush to stop spinning and may also result in poor suction power.

Motor Failure

Another potential cause is motor failure. The side brush is powered by a small motor, and like any mechanical component, it can wear out over time. If the brush is not spinning and there’s no debris build-up, the motor could be the problem.

Software Glitch

Lastly, a software glitch could be at fault. While less common, a problem with the vacuum’s operating system may be causing the brush to malfunction. A simple restart or a firmware update could resolve this issue.

Step-by-Step Solutions To Fix Roborock Side Brush Not Spinning

Tightening the Side Brush

Check if the side brush is loose. If it is, you’ll need to tighten it. First, switch off your Roborock vacuum and carefully turn it upside down. Locate the side brush and check its attachment screw. If it’s loose, use a screwdriver to tighten it. Once done, turn on the vacuum and check if the side brush starts spinning again.

Clean the Side Brush

If the brush is not spinning due to debris build-up, you’ll need to clean it. Start by turning off the vacuum and carefully removing the side brush from its slot. Use a pair of scissors or tweezers to remove any hair or debris tangled in the bristles. Once cleaned, reattach the side brush and turn on the vacuum.

Updating the Software

If the side brush is still not spinning, a software glitch might be the cause. To fix this, you’ll need to update your vacuum’s firmware. Connect the Roborock to your Wi-Fi network and open the Roborock app on your smartphone. Go to the settings and look for any available updates. Download and install the update, then restart the vacuum. After the restart, check if the side brush is working.

Replacing the Side Brush Motor

If none of the above steps work, the motor powering the side brush may have failed. In such cases, you’ll have to replace the motor. For this, you may want to contact the Roborock customer service or a professional repair service. They can guide you through the process, or you can send in your vacuum for a repair.

Remember, regular maintenance can prevent many of these issues. Always keep the side brush clean and check regularly for loose parts or software updates. With these simple steps, your Roborock vacuum should continue to function at optimal efficiency.
