Battery life varies by product, but generally you should charge your FOREO device only when the LED indicator begins flashing to tell you that the battery is running low.
Wash the brush surfaces with soap and water, rinse with clean water and pat dry with a lint-free cloth or towel. Foreo will recommend spraying the device with FOREO's Silicone Cleaning Spray and rinsing with warm water afterwards for optimal results. Allow device to air-dry.
It is important that you only use the advanced switching-charger supplied with your FOREO product. Attempting to use any other charger (including the chargers supplied with other FOREO products) may damage your device’s battery.
