Operation confirmed 【Cutting-Edge Bubble Cleaning Technology for Thorough Cleaning】 Adopting the industry's first ultra-powerful bubble jet technology, this product sends ultra-powerful bubbles into a microbubble pressurized chamber, reaching deep into the teeth. Utilizing the surface tension of the bubbles, it removes remaining debris from the entire mouth, completely solving the problem of conventional electric toothbrushes only being able to clean the surface of the teeth, truly cleaning the entire mouth 360 degrees! When the high-speed airflow is ejected from the fine pores, the trumpet part of the brush head creates the Coandă effect, increasing the intensity and density of the microbubble jet. This allows it to penetrate hard-to-reach areas such as the gaps between teeth, achieving a thorough cleaning effect. Please understand that this is a used item, so only those who understand this are welcome to purchase. #ElectricToothbrush
