Installation
Replacing the side brushes on your eufy RoboVac is a simple, tool-free process. Follow these steps for proper installation:
- Step 1: Turn your RoboVac over to access the side brushes located on the underside of the unit.
- Step 2: Grasp the old side brush firmly and pull it upwards to remove it from its post. You may need to use two hands for a secure grip.

Maintenance
Regular maintenance of your RoboVac's side brushes and other components is essential for optimal performance and longevity. The suggested replacement frequency for side brushes is every 3-6 months, depending on your usage frequency. It is also recommended to perform maintenance on the brushes and other parts once every 2 weeks.
General Cleaning Tips:
- Side Brushes: Regularly check the side brushes for tangled hair or debris. Remove any obstructions to ensure they can rotate freely and effectively sweep debris into the vacuum's path.
- Main Rolling Brush: Periodically remove the main rolling brush and clean any hair or debris wrapped around it. A cleaning tool is often provided with your RoboVac to assist with this.
- Dust Bin and Filter: Empty the dust bin after each cleaning cycle. The filter should be cleaned regularly, ideally once a week, by rinsing it under water. Ensure the filter is completely dry before reinserting it into the dust bin.
- Wheels and Sensors: Wipe down the wheels and sensors to remove any dust or dirt that might impede the RoboVac's movement or navigation.

- Brushes not sweeping effectively:
- Check for tangled hair or debris around the brush bristles or the brush post. Clean thoroughly.

- Unusual noise from brushes:
- Remove the side brushes and check for any foreign objects lodged in the brush mechanism.
- Ensure the side brushes are correctly installed and snapped firmly into place.
- RoboVac leaving debris behind:
- This could indicate worn side brushes that are no longer effectively sweeping. Replace them.
- Also, check the main rolling brush and dust bin/filter for blockages or fullness.
