"Normal Mode" for daily use with standard water pressure. "Spot Mode" has indirect water pressure and is suitable for sensitive areas. "Pulse Mode" is used for gum massage, alternating between strong and weak pressure. "Support Mode" is suitable for cleaning braces and their surroundings with high pressure. "Hold Mode" for designated area cleaning, releasing the water flosser only when the button is pressed. 【6 Memory Water Pressure Levels】 You can select from 6 water pressure levels for each oral irrigator mode. Each pressure level is automatically saved for the next use. The water pressure range is 30-120 PSI, with a pulse frequency of 1400-1800 per minute, providing a powerful and comfortable stream delivery. 【Waterproof/Low Noise/Long Lasting】 The oral irrigator has an IPX7 waterproof design, allowing for safe and convenient use in the shower or bathroom. The noise level is a quiet 75db, so it won't disturb others even when used in the morning or late at night.
