What precautions should I take before charging the device?

The most critical rule is to ensure the charging port is 100% DRY. While it is waterproof for shower use, never plug it in while wet. Always wipe the port and let it air dry before connecting the cable to prevent short circuits.

How do I turn Travel Lock on or off?

To enable or disable Travel Lock, press and hold the Power button for about 5 seconds. Travel Lock helps prevent the flosser from accidentally turning on in your luggage or travel bag.

What should I do if I encounter any product usage issues or concerns?

Please message our team through Amazon first! If you have usage questions or a defective unit, skip the return process. Just send us a message, and we’ll immediately provide a 100% satisfying solution or free replacement.

Can I add mouthwash to the water tank for a fresher clean?

Yes, you certainly can! You can mix mouthwash with warm water in a 1:1 ratio. To keep the device running smoothly, just run a full tank of clean, warm water through the flosser afterward to rinse out any remaining residue.

Why do I need to hold the power button the first time I use it?

To avoid accidental startup during shipping, the flosser is factory-locked. Activate it by holding Power for 2s or placing it on the charging base. Once unlocked, short-press Power for daily quick start.
