If your X10 Pro Omni robotic vacuum cleaner is making an unusually loud noise while it is cleaning, please try the following troubleshooting steps to identify and resolve the issue:

1. Checking the Roller Brush and Brush Guard: Power off the robotic vacuum cleaner and remove the roller brush and brush guard. Inspect the suction inlet and the comb-like structure on the brush guard for any trapped debris. Power on the robotic vacuum cleaner and run it without these parts to verify if the noise persists. If the noise stops, the root cause of the issue is most certainly due to either the roller brush or brush guard.

2. Inspecting the Side Brush: Remove the side brush and run the robotic vacuum cleaner without the side brush. If the noise ceases after removing the side brush, the root cause of the noise is most certainly due to the side brush.

3. Adjusting the Suction Power: Change the suction power settings on the robotic vacuum cleaner. Observe if the noise level fluctuates with different suction power levels. This process can help determine if the noise is related to the robotic vacuum cleaner motor's suction function.

4. Filter Maintenance: Examine the filters for severe blockages. A clogged filter can cause the robotic vacuum cleaner to work harder and emit a louder noise. Try cleaning or replacing the filters when necessary to ensure proper airflow.

5. Inspecting the Wheels: Look for any foreign objects that may be stuck in the wheels, and then rotate the wheels manually to verify if the robotic vacuum cleaner emits a loud noise.

Note: Always power off your robotic vacuum cleaner before performing any maintenance tasks to avoid causing any potential injury or damage.
