The wall-mounted toothbrush holder needs to be plugged into a power source to activate the powerful 90-min high-clean, powerful air-dry, and heating functions.
The toothbrush holder is not plugged into the power supply and can only run the high cleaning and strong air drying functions for 3 min.
After the rechargeable toothbrush holder completes the first 90 minutes of cleaning, it will perform high cleaning, powerful air drying and heating functions for 6 minutes every 3 hours within 12 hours.
After the first 3 minutes of cleaning, the load-brush holder will perform high-level cleaning and powerful air drying for 1 minute every 3 hours within 12 hours.
