5. Operating Principles
The roborock Side Brushes are designed to enhance the cleaning efficiency of your robot vacuum. Their primary function is to sweep debris from edges and corners into the main suction path of the vacuum cleaner.
- Edge Cleaning: When the robot vacuum operates along walls and in corners, the side brush accelerates to approximately 330 RPM to effectively dislodge and collect dirt.
- Open Area Cleaning: In open areas, the brush slows to approximately 130 RPM. This controlled speed helps guide dirt towards the main brush and suction inlet, preventing debris from being scattered into already clean zones.
- Tangle Reduction: Crafted from durable nylon, these brushes are designed to minimize hair tangles, contributing to a more consistent and hassle-free cleaning experience.

6. Maintenance
Regular maintenance of your side brushes ensures optimal performance and extends the lifespan of your robot vacuum cleaner.
- Regular Inspection: Periodically check the side brushes for wear, damage, or accumulated hair and debris.
- Cleaning: If hair or debris is tangled around the brush arms or base, carefully remove it. A small pair of scissors can be used to cut tangled hair if necessary, taking care not to damage the brush or the vacuum.
- Replacement: Side brushes are consumable parts and will wear down over time. Replace them when bristles show significant wear, are bent, or if cleaning performance noticeably decreases. The replacement frequency depends on usage and environment.
7. Troubleshooting
If you encounter issues with your side brushes, consider the following:
- Brush Not Spinning: Ensure the brush is securely installed and the screw is tightened. Check for any obstructions or excessive tangles preventing rotation.
- Reduced Cleaning Performance: Inspect the brushes for wear. Worn or damaged bristles will be less effective at sweeping. Replace the brushes if they are significantly worn.
- Unusual Noise: Remove the brush and check for any foreign objects lodged in the brush mechanism or motor. Reinstall the brush correctly.
