Cordless oral irrigator with Soft, Normal, Jet and Custom modes, a 10-90 PSI pressure range, a 300ml integrated tank and an IPX7 waterproof body. Manufactured by Risun Technology for private label, retail and distribution programs.

The F5037 is a rechargeable portable water flosser designed for daily oral irrigation at home, on the road or in clinical settings. Four cleaning modes - Soft, Normal, Jet and Custom - cover a 10-90 PSI pressure range, and the Custom mode adds 8 individual pressure levels so users can dial in the exact flow they prefer. A digital LCD screen shows battery status and water pressure, while a 300ml integrated tank reduces the number of refills per session.
The unit runs on a 2500mAh Li-ion battery charged through a DC port in less than 6 hours, delivering more than 40 minutes of use at Normal mode. A 2-minute timer, mode memory and mode preset support consistent daily routines, and the IPX7 waterproof housing allows rinsing under running water. A hidden compartment stores one nozzle, which keeps the device compact for travel and hotel use.
The screen displays battery level and current water pressure, so users know the remaining runtime and the active intensity before starting a session.
Beyond the three preset modes, Custom mode offers 8 water pressure levels for users with sensitive gums or specific irrigation routines.
Jet mode allows the user to control water flow directly, targeting specific interdental areas while limiting water consumption.
The jet ramps from weak to strong over 3 seconds, giving the gum line time to adjust and reducing the shock of a full-pressure start.
Two buttons handle power and mode selection, and mode memory plus mode preset restore the last-used setting for faster repeat use.
The integrated 300ml reservoir and the concealed nozzle storage keep the device self-contained for travel, hotel and clinical use.

The F5037 is the current platform in this specification. Configuration options documented for the model include the four-mode set (Soft, Normal, Jet, Custom), the 8-level Custom pressure scale, the preset and memory functions, and the hidden nozzle bay. Colourways, packaging formats, MOQ and lead times are not part of the published specification, so buyers should confirm these points directly with the sales team before committing to an order.
The body is built from an ABS housing with a food-grade soft bristle component, combining structural rigidity with contact-safe materials for an oral care device. Inside, the 300ml tank is integrated into the chassis rather than clipped on, which keeps the footprint compact and the centre of gravity stable in hand. The front face carries the digital LCD and the two-button control cluster, and a concealed bay at the base holds one nozzle between uses. IPX7 sealing protects the electronics during rinsing and normal bathroom use.
Risun Technology supplies private label brands, retailers and distributors, and the F5037 platform is positioned for those programs. The four cleaning modes, the 8-level Custom scale and the mode preset behaviour give brands room to define a positioning around sensitive-gum care, travel convenience or clinical support. Buyers should confirm branding artwork, packaging format and program terms with the sales team, as these details are not fixed in the published specification.
