You can try the general troubleshooting steps for noise issues and let us know what happens:

- Remove the dust collector, clean the suction inlet, and check to make sure the filters are properly aligned.

- With the dust collector removed from the unit, hold the vacuum upright with the bumper facing up, the suction "hole" facing downwards. Shake out any debris that might be stuck in the suction fans inside the machine.

- Reassemble the dust collector properly.

- Clean the brushes and wheels out.

- Remove the brush guard and rolling brush, run the vacuum without the 2 parts to see whether the noise persists when running without the parts. You can refer to this article for further troubleshooting. 

- Check whether there is a clicking sound if you spin the side brushes with your hands. If yes, please refer to this article for further troubleshooting. 

- The noise levels in higher suction levels (like in Max Suction) are louder than in Standard Suction. Please cycle through the suction levels and adjust to Standard Suction for a try.

If the noise persists, please contact us with the troubleshooting details and a video depicting the noise issue, so we can assist you further.
