Why does the COSLUS water dental flosser only have three modes?
Developed over 3 years through extensive user testing, this flosser offers 3 simplified modes for ultimate ease of use. Suitable for all ages, from teens to seniors, it is built to deliver a premium lifespan of 3 years.
What is the intensity of the water pressure? Which mode should I choose?
This flosser features three pressure modes: high (Clean), medium (Message), and low (Soft). First-time users should start with the gentle Soft mode. Any initial gum bleeding is normal and should subside quickly as gums adapt.
Do you need to add water a lot during use?
No, this water tank has an upgraded, super-large capacity of 300ml, which is enough for a 2-minute cleaning session.
Where can you get replacement tips?
Nozzle Replacement: For best results, replace every 3 months. Find accessories on our product page, website, and COSLUS store.
Does the package include the charging adapter?
The adapter is not included to avoid waste. You can charge it using any standard 5V adapter (like one from a phone or tablet). If needed, you can purchase a compatible adapter from COSLUS.
