Basic Operation
Follow these steps for effective water flossing:
- Select Mode: Before turning on the flosser, press the "M" (Mode) button to cycle through the modes (Strong, Normal, Soft, Pulse) and select your preferred setting. The device has a memory function and will start in the last used mode. For first-time users, it is recommended to start with the "Soft" mode.
- Positioning: Lean over a sink. Place the tip of the nozzle into your mouth, pointing it towards your teeth and gumline at a 90-degree angle. Keep your mouth slightly closed to minimize splashing, but not so closed that it restricts water flow.
- Start Flossing: Press the Power button to turn on the device. Guide the tip along your teeth and gums, moving it slowly from tooth to tooth. Allow the water to flow into the sink.
- Continue: Continue flossing until you have cleaned all areas of your mouth, including between teeth and along the gumline. Do not remove the flosser from your mouth while it is operating to prevent water from splashing.
- Finish: Press the Power button again to turn off the device.

Maintenance
Cleaning the Device
Regular cleaning ensures hygiene and extends the lifespan of your water flosser:
- After each use, remove the jet tip by pressing the nozzle lock button and pulling the tip upwards. Rinse the tip under clean running water.
- Detach the water reservoir and empty any remaining water. Rinse the inside of the tank thoroughly with clean water. The wide-mouth design makes this easy.
- Wipe the exterior of the main unit with a soft, damp cloth. Do not submerge the main unit in water, although it is IPX7 waterproof, it is best to avoid prolonged submersion for cleaning.
- Allow all parts to air dry completely before reassembling or storing.
Storage
When not in use, store your WAFLOO water flosser in a cool, dry place, away from direct sunlight. The included travel bag is ideal for both travel and home storage to protect the device and its accessories.

| Device does not turn on. | Low battery; Power button not pressed correctly. | Charge the device fully. Ensure the power button is pressed firmly. |
| Water pressure is weak or inconsistent. | Water tank is empty; Nozzle is clogged; Air in the pump. | Refill the water tank. Remove and clean the nozzle. Run the device with the nozzle removed to clear air. |
| Water leaks from the device. | Nozzle not securely attached; Water tank not properly seated; Base cover not closed tightly. | Ensure the nozzle is clicked firmly into place. Reattach the water tank securely. Verify the base cover is tightly closed. |
