As a result, the risk of the product malfunctioning due to water leakage is reduced. It also has a strong dry-running capability and is less likely to break down even after long hours of use, significantly extending the life of the product. 【Clean away dirt that can't be removed by brushing with water flow】 Oral irrigators use the power of water flow to remove dirt from the gaps between teeth and periodontal pockets that toothbrushes can't reach. It is said that even with careful brushing, only about 60% of the dirt can be removed by brushing alone. This product can clean away dirt that cannot be removed by a toothbrush or floss with the water pressure (30~140PSI) of water released from the thin nozzle tip. 【Easy and understandable operation】 Understanding that many elderly people need this product, and considering that conventional products have 3 to 5 modes, which are displayed in English, making it difficult for some people to understand. Therefore, our new product eliminates complexity and is divided into 5 levels according to the strength of the water pressure. The button display also uses Japanese, and the strengths are "Pulse", "Weak", "Medium", "Normal", and "Strong", and can be operated with one button. 【3 types, 4 nozzles & 360° rotation】 Comes with a total of 4 replacement nozzles of 3 types. Two water flow nozzles are included, so you can use them with your family. Of course, a point polishing nozzle is also included, so you can clean hard-to-reach areas such as areas with misaligned teeth or orthodontic treatment. A tongue cleaning nozzle is also included to keep your tongue clean. The 360° rotatable nozzle design allows you to clean areas that are difficult to reach with a toothbrush. 【300ML large capacity tank & IPX7 waterproof】 Based on long-term analysis and feedback from many users, we have equipped it with a 300ML water tank.
