A: If the noise from your Xiaomi Vacuum Cleaner G20 increases when using the 2-in-1 Brush attachment, here are what you can do to troubleshoot and address the problem:
1. Inspect the 2-in-1 Brush attachment, including the roller brush and its housing, for any debris, hair, or other obstructions. These can cause the brush to spin irregularly or generate more noise than usual. Clean out any blockages carefully;
2. Verify that the 2-in-1 Brush attachment is securely connected to the vacuum cleaner's wand or hose. A loose attachment can cause vibrations and increased noise during operation;
3. Examine the roller brush within the 2-in-1 Brush attachment. If the roller brush is damaged, bent, or has trapped debris, it can cause excessive noise. Clean the roller brush thoroughly and ensure it rotates smoothly without any resistance;
4. Inspect the roller brush and other parts of the 2-in-1 Brush attachment for signs of wear and tear, such as worn bristles or damaged bearings. Replace any worn-out components to reduce noise and improve performance.
