Possible Reasons:
- Air leakage due to improper installation of components.
- Blockage in tubing or suction tip.
- Low battery.
- Low suction level setting.
Solution:
1. Seal Inspection
Focus on checking that both ends of the silicone connecting tube are securely inserted into the ports of the main unit and the collection cup, and that the collection cup lid is tightly closed and locked to prevent air leakage.
2. Blockage Cleaning
Remove the silicone suction tip, connecting tube, and spray mask, then rinse and clean each part thoroughly, especially the filter grid area inside the suction tip and any mucus on the inner wall of the connecting tube.
3. Battery/Level Check
Ensure the device has sufficient battery power (e.g., the indicator light stays green) and adjust the suction level to a higher setting before testing the suction again.
If the issue cannot be solved still, please escalate to after sales support.
