Why doesn’t the UV light of the Xiaomi Dust Mite Vacuum Cleaner 2 Pro work?

If the UV light of the Xiaomi Dust Mite Vacuum Cleaner 2 Pro does not work properly, there are several possible reasons related to its safety mechanism and operating conditions. The UV light is designed to function only under specific circumstances to ensure both safety and effectiveness.
Please check the following points for troubleshooting:
  1. The UV light will not activate if the vacuum cleaner is not in direct contact with the cleaning surface. If the device is lifted too far from the surface (more than 3 cm ± 2 cm), the safety system prevents the light from turning on. Ensure that the vacuum cleaner remains close to the surface while in use.
  2. The rollers at the bottom must press down properly to trigger the internal micro switch. If dust, hair, or other debris is stuck in the rollers, the micro switch cannot be engaged, which stops the UV light from functioning. Cleaning the rollers regularly can restore proper UV light operation.
