Product Overview
The INSMART Water Flosser is designed for comprehensive oral hygiene, offering deep cleaning for teeth and gums. It features adjustable pressure levels and a variety of specialized nozzles to cater to individual needs and ensure thorough removal of food debris and plaque.
- 360° Deep Cleaning: This professional water flosser provides powerful pulsation (1400-1800 pulses per minute) to effectively remove food debris hidden deep within the mouth, addressing gum issues, teeth stains, and bad breath. Its large 600ml water tank supports extended use for individuals and multiple family members.
- 10 Adjustable Water Pressure Settings: Customize your cleaning experience with 10 pressure levels (10-130 PSI). Levels 1-3 are suitable for children, sensitive teeth, and beginners. Medium pressure (5-7) is ideal for most users, while high pressure (10) is designed for adults and experienced users, ensuring thorough cleaning.
- Large 600ml Capacity & Leak-Proof Design: The water tank offers ample capacity for up to 500 seconds of continuous water dispensing. A 1-meter flexible inlet hose allows for convenient long-distance use. The leak-proof design prevents spills, and the 360° rotating nozzle ensures all areas of the mouth are accessible for cleaning.
- 8 Specialized Nozzles: The flosser includes 3 regular high-pressure nozzles and 5 special-purpose nozzles: 1 orthodontic nozzle, 1 tongue cleaning nozzle, 1 periodontal nozzle, 1 stain nozzle, and 1 toothbrush nozzle. These diverse tips enable deep cleaning of interdental spaces and gum lines, areas often missed by traditional brushing and flossing.

Operating Instructions
- Initial Pressure Setting: When using the oral irrigator for the first time, begin with a low water pressure setting (Pressure 1-3) to allow your gums to adjust. Gradually increase the pressure to a comfortable level (Medium Pressure 5-7 for most, High Pressure 10 for experienced users).
- Power On: Turn the main unit's knob to the desired pressure setting.
- Position Nozzle: Place the nozzle tip into your mouth, aiming it at the gumline at a 90-degree angle.
- Activate Water Flow: Turn on the handle switch to start the water flow. Keep your lips slightly closed to prevent splashing while allowing water to drain into the sink.
- Flossing Technique: Guide the water jet along your gumline, pausing briefly between teeth. Ensure you clean both the front and back surfaces of your teeth. The 360° rotating nozzle allows for easy access to all areas.
- Changing Modes: The device features three pressure modes: Normal, Pulse, and Point. Use the mode switch button on the top of the unit to cycle through these options. The mode memory function will automatically shut down the device after 2 minutes of continuous use.
- To Stop Use: First, turn off the handle switch. Then, turn the gear knob on the main unit to the "OFF" position. Finally, turn off the main switch in the center of the irrigator.

Maintenance
- Empty and Dry Water Tank: After each use, empty any remaining water from the tank. The removable 600ml water tank can be easily detached for cleaning and drying to prevent mold and bacterial growth.
- Clean Nozzles: Rinse the nozzles thoroughly under running water after each use. For deeper cleaning, periodically soak them in a solution of 2 parts water to 1 part white vinegar.
- Wipe Down Unit: Wipe the exterior of the main unit with a soft, damp cloth. Do not submerge the main unit in water.
- Storage: Store the water flosser in a clean, dry place. Ensure the handle and hose are properly coiled and stored to prevent kinks.
