1. Introduction
The Waterpik Waterflosser NANO WP-250 is an advanced oral irrigator designed to enhance daily oral hygiene. It utilizes a combination of water pressure and pulsations to clean deep between teeth and below the gumline, areas traditional brushing and string floss may miss. Regular use can significantly improve gum health and remove plaque from treated areas.
2. Product Overview
The Waterpik Waterflosser NANO WP-250 is a compact oral irrigator featuring a main unit with a water reservoir, a handle with a water flossing tip, and a pressure control dial. The reservoir is transparent blue with measurement markings, and the unit is primarily white with blue accents. The handle connects to the main unit via a coiled hose.

4. Safety Warnings

- Always read all instructions before initial use.
- Keep out of reach of children.
- Do not direct water under the tongue, into the ear, nose, or other delicate areas.
- Use only as directed for oral hygiene.
5. Setup Instructions
- Unpack the Unit: Remove all components from the packaging.
- Place the Unit: Position the Waterflosser on a flat, stable surface near a power outlet and a sink.
- Fill the Reservoir: Lift the hinged lid on the reservoir and fill it with lukewarm water. You may also add mouthwash as recommended by your dental professional. Place the reservoir back onto the base.
- Insert Tip: Press the tip firmly into the center of the handle until it clicks into place. To remove a tip, press the eject button on the handle.
- Prime the Unit (First Use): If using for the first time, set the pressure control dial to high. Direct the tip into the sink. Turn the unit ON until water flows from the tip. Turn the unit OFF.
6. Operating Instructions
- Adjust Pressure: Select the desired pressure setting using the dial on the base unit. Start with the lowest setting and gradually increase as comfortable.
- Position the Tip: Lean over the sink and place the tip in your mouth. Close your lips enough to prevent splashing, but allow water to flow from your mouth into the sink.
- Start Flossing: Turn the unit ON. Direct the water stream at a 90-degree angle to your gumline. Begin with the back teeth and work your way to the front. Glide the tip along the gumline, pausing briefly between teeth.
- Clean All Areas: Continue until you have cleaned the inside and outside of both your upper and lower teeth. The 60-second reservoir capacity is designed for a thorough cleaning.
- Turn Off: When finished, turn the unit OFF.
- Empty Reservoir: Empty any remaining water from the reservoir after each use to prevent bacterial growth.
7. Maintenance
Cleaning the Unit:
- Exterior: Wipe the exterior of the unit with a soft cloth and mild, non-abrasive cleaner. Do not immerse the unit in water.
- Reservoir: The reservoir can be removed and cleaned with warm soapy water. For thorough cleaning, it is top-rack dishwasher safe. Ensure it is completely dry before reattaching.
Hygienic Storage:
For hygienic storage and travel, the reservoir can be inverted and placed over the main unit. This compact configuration helps protect the unit from dust and debris when not in use.
Replacing Tips:
- Waterpik recommends replacing flossing tips every 3-6 months, or sooner if the tip becomes damaged.
