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.

How can I keep my water flosser working at its best?

After about one month of regular use, or when buildup is visible, clean the stainless-steel filter at the bottom of the suction tube. Rinse with clean water or gently brush away buildup to help maintain smooth water flow.

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.

How do I use the Travel Lock and charge my flosser?

First-use unlock: long-press 2–3s (then single-press ON/OFF). To relock for travel, long-press 5s. Fully charge before first use.

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.
