What to do if the Xiaomi Robot Vacuum S40C fails to collect dust?

If the Xiaomi Robot Vacuum S40C fails to collect dust, it can be due to improper installation, filter blockage, brush obstruction, or sensor malfunction.
If the robot vacuum fails to collect dust, please refer to the following steps:
1. Please check if the dust compartment of the robot vacuum is full and try to clean it;
2. If the dust compartment, dust compartment cover, or filter is not properly installed, the robot will fail to detect the dust container and display a dust collection failure;
3. A clogged or damp filter can reduce suction power and cause the system to mistakenly report a dust collection failure;
4. Tangled hair or debris in the brush, side brush, or suction inlet can block dust flow and lead to a dust collection failure alert;
5. Dust-contaminated or malfunctioning internal sensors can incorrectly determine that dust collection has failed, resulting in an error notification;
6. If the above methods do not resolve the issue, please contact the local after-sales service center.
