The Coslus C20 Cordless Rechargeable Water Flosser is currently available on Amazon for $6.99 after applying the coupon code “BQ385MEV,” according to a deal report from IGN. This represents an 83% discount from the original $42 list price, making it one of the most affordable oral irrigation options currently on the market.
The discount is available to all shoppers and does not require an Amazon Prime membership. The Coslus C20 is positioned as a budget-friendly alternative to high-end dental equipment, such as the Philips Sonicare Power Flosser, by providing a portable, cordless method to remove plaque and food debris from between teeth.
According to Amazon product data, the C20 is a top-selling flosser with more than 51,000 user reviews. The device functions as an oral irrigator, using a pressurized stream of water to mimic the results of traditional string flossing.
Coslus C20 Technical Specifications and Features
The Coslus C20 is a fully integrated cordless design, which distinguishes it from countertop models that require a permanent plug and a separate, stationary water tank. This portability allows for easier travel and requires significantly less bathroom counter space.
Key hardware specifications for the device include:
- Water Capacity: A built-in 300ml water tank.
- Pressure Settings: Three distinct modes—low, medium, and high—to accommodate different gum sensitivities and the removal of stubborn particles.
- Battery Life: The manufacturer claims the battery lasts up to 30 days of normal daily use.
- Charging: The unit recharges via an included USB Type-A cable.
- Accessories: The package includes multiple nozzle tips designed to target specific areas of the gums.
ADA Seal of Acceptance and Market Positioning
Beyond its price point, the device has a notable professional credential. In June, Yahoo Finance reported that the Coslus C20 appeared to have received the ADA Seal of Acceptance.
The C20 competes directly with professional-grade oral irrigators by offering the same basic utility—water-jet cleaning—at a fraction of the cost.
For users prioritizing oral hygiene on a budget, the combination of the ADA Seal and the current 83% discount makes the C20 a high-value entry point into water flossing.
