U20 Portable Water Flosser

U20 is designed for both home use and travel through two interchangeable water tanks. The portable tank keeps the irrigator easier to carry on the go, while the larger 250 mL tank provides greater capacity for daily use at home. Both tanks connect to the same main body, so users can switch capacity according to the situation without changing the device itself. One irrigator therefore adapts to different routines through a simple change of tank.

Inspired by pebbles shaped by flowing water, U20 uses a broad superelliptical form with soft, continuous curves. The portable tank is integrated into the lower body: when closed, it aligns with the housing to preserve a compact, complete silhouette; when pulled down, the visible structural change naturally signals filling and use. A high-gloss upper body contrasts with the matte UV-finished tank, further defining the two sections through differences in sheen and touch.

Pull the portable tank downward to reveal the filling opening and add water directly, without removing multiple parts.

Press the power button to begin cleaning, then select from three intensity levels and three modes according to gum sensitivity and daily care needs.

The curved nozzle helps direct the water flow towards different areas of the mouth with less wrist adjustment, making daily cleaning more comfortable to control.

After use, the tank withdraws into the body for compact storage. From filling and adjustment to cleaning and storage, the operation remains simple and continuous.

U20 centres its differentiation on an air-water mixing pump. By introducing air into the water stream, the system forms a mixed flow that reduces the amount of water required for each cleaning session while maintaining effective coverage. The softer flow also improves contact comfort along the gums, allowing water efficiency and oral comfort to be addressed through the same core pumping technology.
