Can I put mouthwash in the C30 300ml tank?

Yes! Use up to a 1:1 water-to-mouthwash ratio or 3% hydrogen peroxide. Maintenance Tip: Always flush the unit with a full 300ml tank of clean warm water immediately after to keep the pump residue-free.

Will C30’s strong water pressure hurt sensitive gums?

Start with the “Soft” mode if you have sensitive gums. C30’s WaveFlow technology buffers the water stream for a gentle clean. Once adapted after 1-2 weeks, you can switch to higher modes for deeper clean.

Do I need to refill the 300ml tank mid-floss?

No refills needed! The 300ml (10 oz) tank offers 60s+ of continuous flow for a full-mouth clean in one go. For fast refills, simply open the large flip-lid on the back directly under your faucet.

What if water enters the charging port?

The rubber cap protects the port during shower use. If water gets in, DO NOT plug in the cable. Shake off water and allow it to air dry completely in a ventilated space before charging.

Is usmile C30 suitable for braces or implants?

Absolutely! It includes a specialized Orthodontic S-Shaped Nozzle designed for brackets and dental work. The 360° rotating tip reaches deep molar gaps that standard string floss misses.
