The listing says continuous light operation requires the lid to be fully closed.

Listing details to confirm

The listing describes five modes as Quick Refresh, Daily Renewal, Deep Remove, Thermal Dry and Ultrasonic, while also describing the device as a 45 kHz, 25W ultrasonic cleaner with a built-in 254 nm light. It does not clarify whether the light operates in every mode or whether thermal drying uses the ultrasonic system. The claimed 30 dB noise level and cleaning-performance comparisons are listing claims, not independent measurements.

The supplied evidence includes aggregate ratings but no customer-review summary, so it does not establish specific customer-reported strengths, concerns or reasons for the ratings. The rating distribution is largely favorable, but offers no evidence about cleaning effectiveness, noise or light performance. Buyers should treat the 45 kHz frequency, 25W power and claimed operating noise as listing specifications rather than customer-verified outcomes.
