Applicable to:

RoboVac G20, RoboVac 11S, RoboVac X8

To confirm whether the noise comes from the rolling brush part, please remove the brush guard and rolling brush, and run the vacuum without the 2 parts. Let us know whether the noise persists when the vacuum is running without the 2 parts.

If the vacuum runs quietly with the 2 parts unattached, please double-check whether the rolling brush and brush guard are properly installed, whether the rolling brush is not completely cleaned, or the rubber part of the brush guard / 2 ends of the rolling brush are worn out.

Please send us pictures of the 2 rolling brush ends, the white connector on the vacuum (where the rolling brush connects to the vacuum), and the brush guard, so we can identify the cause for you. Here are the photos for your reference.

If the noise persists, then it's not because of the rolling brush or brush guard and the troubleshooting would be different.

Please scroll down to email us with a video depicting the noise so we can identify where the noise comes from and assist you further.
