This flosser features three pressure modes: high (Clean), medium (Message), and low (Soft). First-time users should start with the gentle Soft mode.

No, this water tank has a upgrade super larger capacity of 300ml, cleaning for 2 minutes is enough. Does the package include the charging adapter? No. But I think it doesn't matter, because everyone has tons of adapters at home to use. It is enough to get a cable.
