Operation Steps

Start Work: Very important! Ensure the device is fully charged before using it for the first time by connecting the USB cable to the recharging socket and turning on the power. This device cannot be used while being charged.

Step 1: Fill water into reservoir

Note: Ensure that the device is powered off when filling water into the water tank.

Rotate the water tank clockwise and pull to remove the water tank. Fill water into the water tank. After filling water, align the water tank with the buckle point, and rotate counterclockwise to install it back.

Water temperature should be less than 40°C.

Step 2: Install the nozzle

Insert the nozzle into the top hole of the main unit and when you hear a "click" sound, the installation is successful. Rotating the nozzle can adjust the direction of water outflow. To replace the nozzle, press and hold the nozzle removal button, and then remove the nozzle.

Step 3: Select the mode

There are 4 modes for the product. You can select the required mode by tapping the mode button when the device is powered off, and the functions of each mode are as follows:

• Standard modes: Long press the On/Off button to enter the working mode. Short press the mode button to change between 4 modes: Normal, Soft, Pulse, DIY. The machine will be powered off if pressing the On/Off button.
• DIY mode: If there is no suitable pressure under standard modes, you can enter DIY mode to choose 8 water pressure gears. In the working state, press the mode button to select the DIY mode, and long press the mode button for about 3 seconds. Until the DIY indicator flashes quickly, you can change water pressure by short pressing. After selecting the required gears, loosen the mode button. After 3 seconds, it will exit from choosing gears, and the indicator will stop flashing.
• Power Level Display: Long press the mode button to display the current power level, indicated by the number of lights on. When charging, the lights flash in sequence. After fully charged, all lights are on. If the power is too low during use, the indicator light will flash to remind the user to charge. When the indicator light flashes 3 times, the device automatically shuts down.
• Working time: Approximately 2 minutes.
• Memory mode: When powered on, the product will enter the working mode before the last shutdown.
• The device should be used vertically to ensure optimal working state. After running for 120 seconds in any mode, the device automatically powers off.

Step 4: Preparation before use

Before use, bend over the sink slightly, extend the nozzle into your mouth, aim at your teeth, gums or slit between the teeth. Rotate the nozzle to adjust the direction of water outflow, ensure that the water flow is perpendicular to the flushing position, and open your mouth slightly to facilitate the flushing water to flow out of your mouth.

Tips: When using the oral irrigator for the first time, start from the lowest gear, and gradually adjust the water pressure after the oral cavity adapts. Itching or slight gum bleeding may occur, which is a normal phenomenon and usually stops within 1~2 weeks.

Step 5: Using

Press and hold the On/Off button for 0.6s to power on the device. If you need to pause during use, press the On/Off button lightly. If you continue to use it, please press the On/Off button again. The product has a timed power-off function in 120s. Before automatic power-off, the water in the tank will be used up. If you need to continue to use, first lightly press the On/Off button to turn off the machine, add water, and then start the equipment. After use, turn off the device.

Tips for Use: To obtain a better cleaning effect, start from the molars (posterior teeth) and clean in the direction of incisors. When cleaning, move the nozzle 90° along the gum line and stay between the teeth for a short time. When using the product, keep lips slightly closed to prevent water from flowing sideways, leaving a certain gap to facilitate the water in the mouth to flow freely to the wash basin.

Cleaning and Maintenance

Clean the main unit:

1. Please use water or neutral detergent to clean the product. Do not use corrosive or abrasive detergent. Do not use hot water over 50°C to clean any part of the machine to avoid damage to the product and reduce its performance.
2. Do not soak the oral irrigator in water. If necessary, wipe the surface of the device with a soft cloth dipped in a mild non-corrosive detergent.

Clean the water tank:

1. Grab the product body with your left hand, grab the water tank with your right hand, rotate it in the counterclockwise direction to remove the water tank.

3. After cleaning, align the water tank with the buckle point and then rotate clockwise to put it back.

Removal of hard water precipitates:

1. Hard water precipitates may accumulate on the device, depending on the mineral content in water. If it is not removed in time, the product performance will be reduced.
2. Align the nozzle with the sink, turn on the machine for running until the water is used up. Then fill the water tank with clean warm water and repeat the above operation to carry out cleaning. Cleaning operation should be repeated every 1-3 months to ensure performance.
