WT-288 Cordless Water Flosser
A 300 ml smart model with four cleaning modes, three intensity levels, charging base, and three included nozzles.

Give your customers powerful interdental cleaning with portable designs, adjustable performance, and flexible product configurations for home and travel use.

A cordless water flosser is a portable, battery-powered oral care device that cleans between teeth and along the gumline with a focused stream of pressurized water. Rapid water pulses help remove trapped food particles, plaque, and debris from areas that are difficult to reach with a toothbrush.
Compared with traditional string floss, it offers a more convenient and comfortable cleaning experience for daily use. A cordless water flosser is especially suitable for users with braces, implants, bridges, crowns, or sensitive gums. Its compact design, rechargeable power system, and built-in water tank make it ideal for home, travel, and on-the-go oral care.

Features
After each use, empty the water reservoir completely and rinse it several times with clean, warm water. Remove the nozzle, wash it under running water, and check the opening for trapped debris. Wipe the cordless water flosser handle with a soft, damp cloth, especially around the buttons and charging port. Store the unit upright with the tank cap open, and allow all components to air-dry fully before the next use.


Fill the reservoir with lukewarm water and securely insert the selected nozzle. Start your cordless water flosser at the lowest pressure setting, lean over the sink, and place the tip inside your mouth before switching it on. Aim the water stream at the gumline at a 90-degree angle. Move slowly from the back teeth toward the front, pausing briefly between each tooth and cleaning both inner and outer surfaces.
A cordless water flosser typically lasts around three to five years, depending on battery quality, motor durability, water exposure, and daily maintenance. Rechargeable batteries gradually lose capacity after repeated charging cycles, while mineral buildup from hard water can reduce pump performance. Regularly cleaning the reservoir and nozzle, allowing the unit to dry, and using clean water can help maintain stable pressure and extend the product’s service life.


A waterproof cordless water flosser is designed for reliable use in wet bathroom environments. An IPX7-rated structure helps protect the internal components from water exposure during daily cleaning and rinsing. The sealed housing also makes the handle easier to maintain after use. For safe charging and longer service life, keep the charging port dry and ensure the protective cover is fully closed before operation.
A standard cordless water flosser should not be used for nasal irrigation unless the product is specifically designed for both oral and nasal care. Dental water pressure may be too strong for sensitive nasal tissues, potentially causing discomfort, irritation, or bleeding. Saline solutions may also damage internal components not designed for saltwater use. To reduce contamination risks, use a dedicated nasal irrigation device with separate accessories and manufacturer-approved pressure settings.

The standard MOQ for a cordless water flosser is 1,000 pieces per model. For a first trial order, Besman can normally support 500 pieces, depending on the selected model, color, packaging, and stock situation. A higher quantity may be required for custom plastic colors, new molds, special accessories, or fully customized retail packaging.
Cordless water flosser samples normally require 7–15 working days, depending on whether you select a standard sample or request logo, color, packaging, or structural changes. Standard available samples can usually be arranged faster. Before shipment, the sample configuration, nozzle set, charging accessories, and packaging requirements will be confirmed to reduce differences during later mass production.
Besman can support relevant compliance documents and testing for cordless water flosser projects, including CE and RoHS requirements for suitable models and markets. Exact documentation should be confirmed according to the product configuration, destination country, battery type, charger, and packaging. Additional testing or certification can be discussed before order confirmation to avoid compliance gaps after production.
Mass production for a cordless water flosser normally takes about 35–45 days after the deposit and final approval of artwork, color, accessories, and samples. The schedule may change for new molds, special packaging, customized electronic functions, or peak-season orders. Confirming specifications and artwork early helps you reserve production capacity and reduce avoidable delays before shipment.
Quality control for a cordless water flosser can cover incoming materials, assembly checks, water-pressure performance, pulse operation, charging, battery function, leakage, waterproof structure, aging, appearance, and final packaging inspection. The exact test plan depends on the selected model and project requirements. Test reports or inspection records can be discussed before mass production and shipment.
Yes. Additional replacement nozzles can be supplied with the initial cordless water flosser order or arranged for later repeat purchases. You can select standard, orthodontic, periodontal, plaque-control, or tongue-cleaning tips according to the compatible model. Nozzle quantity, individual packaging, color identification, and retail pack configuration should be confirmed before quotation and sample approval.
