What to do if the Xiaomi Robot Vacuum X20+ has weak suction?

Question

Accepted Answer

If the Xiaomi Robot Vacuum X20+ has weak suction, you can follow these troubleshooting steps:
1. Check whether the dust compartment is full and empty it promptly. Remove dust and debris from the filter, rinse it with clean water if needed, and ensure it is completely dry before reinstalling. This helps maintain stable airflow and suction performance.
2. Remove hair, threads, or other debris wrapped around the main and side brushes. Obstructions can limit brush rotation, reducing cleaning efficiency. Regularly cleaning the brushes ensures smooth operation and consistent suction during use.
3. Examine the suction port and internal air channel for blockages caused by dust or debris. Clearing these pathways allows air to flow freely, which directly improves suction strength and cleaning efficiency.
4. Open the Xiaomi Home App and verify the suction mode. Switching to a higher suction level can enhance cleaning effectiveness, especially on carpets or areas with heavy dirt.
5. If weak suction persists after all the steps above, contact the local after-sales service center for professional inspection.
