【Industry's First High Output, Cleans the Mouth】Oral irrigators are products that use water pressure (30-140PSI) released from a thin nozzle to clean away dirt that cannot be removed by toothbrushes or floss alone. With a rotation speed of 1400-2100r/min, they quickly blast away dirt on teeth and food debris caught in gaps, washing away dirt from areas with misaligned teeth. 【5 Modes & 6-Level Adjustment & Memory Function】Equipped with 5 operating modes that allow you to choose the strength according to the condition of your gums, and you can switch freely with one button. With the 6-level adjustment function, you can freely adjust the intensity of the water pressure, eliminating the dissatisfaction of water pressure being too strong or too weak at the specified levels, allowing you to find a comfortable water pressure and meet various oral care needs. 【2 Types, 4 Nozzles & 360° Rotation】Comes with 4 replacement nozzles in 2 types. There are 3 water flow nozzles, which can be used with your family. Of course, there is also 1 point-cleaning nozzle, which can be used to clean hard-to-reach areas such as areas with misaligned teeth or orthodontic appliances. The 360° rotatable nozzle design allows you to clean even hard-to-reach areas of your teeth. 【300ML Large Capacity Tank & Waterproof Design for Use in the Bath】Equipped with a 300ML large-capacity tank, reducing the number of times you need to refill water. You can see the remaining amount of water in the tank at a glance. The tank is removable, and you can easily clean the tank and the inside of the refill. This is a waterproof jet washer, so you can use the oral irrigator anywhere, such as in the bath or shower, even if you are concerned about water splashing. It has a waterproof design that allows it to be used in the bath, but storing or leaving it in a place with high temperature and humidity may cause malfunctions. Please bring it into the bathroom only when using it. *Do not soak in water for a long time. 【Convenient Type-C Charging / USB & Easy to Carry】It is rechargeable with a built-in 2000mAh lithium battery, so you can use it even where there is no power outlet. It can be used for up to about 40 days with a full charge of 8 hours. It also has a function to check the remaining charge. When the power is turned off, press "M" for about 1 second, and you can check the remaining charge. It is a portable type, and unlike the stationary type, it does not get in the way even when used in a compact washroom in an apartment or condominium.
