FAQs

How often should I replace the main brush?

It is generally recommended to replace the brush every 6 to 12 months, depending on the frequency of use and the amount of debris in your home.

Can I use this on a Roborock S7 or S8?

No, the CP21800 is specifically designed for the Qrevo Curv, Qrevo Edge, and Saros series and is not physically compatible with S-series models.

Is the brush safe for hardwood floors?

Yes, the rubber material is designed to be gentle on hard surfaces while maintaining effective cleaning contact.

Does this pack include the brush cover?

No, this product includes only the replacement main brush (1 pc).

What should I do if the brush doesn't fit properly?

Ensure your vacuum model matches the compatibility list and check that no old plastic debris from a previous brush is lodged in the housing.

Troubleshooting

Robot reports a 'Brush Roll Blocked' error

Remove the brush and check for tangled hair or debris trapped around the ends of the roller.

Increased noise during cleaning

Verify that the brush cover is properly seated and the brush is not misaligned in its housing.

Poor debris pickup

Inspect the rubber blades for signs of wear or tearing; replace the brush if the blades are significantly damaged.
