Follow these instructions on how to use a Waterpik® Water Flosser:

1. Fill the reservoir with warm water and place firmly on the base.
2. Select a tip and click into the handle. (Note: If this is the first use, set the pressure control dial to high. Point the tip into the sink and turn on until water flows. Turn the unit off.)
3. Start with the lowest pressure setting, lean over the sink, place tip in your mouth.
4. Turn unit on. Close lips enough to prevent splashing, let water flow from your mouth into sink.
5. Aim the tip at the gumline.
6. When finished, turn unit off and use the tip eject button to remove the tip.

Depending on the Waterpik® Water Flosser model, you can use the in-handle pause or on/off switch to stop water flow if needed. You can also aim the tip using the rotating base. (These features are not available on all models.)

Learn how to clean your Water Flosser in 5 easy steps.

Step 1: Clean the outside of the unit.

Clean the outside of the product when necessary by using a soft cloth and mild non-abrasive cleanser.

Step 2: Clean the water reservoir.

• Remove the water reservoir from the unit. (Refer to your product manual if you need assistance).
• If using a countertop model that contains a small black reservoir valve, remove the valve by pushing on it from the bottom. Clean the valve by massaging it under warm water for 30-45 seconds and set aside.
• Place the reservoir in the top rack of your dishwasher for cleaning. We recommend air drying instead of a heated dry cycle.
• If you removed a valve, place it back in the reservoir before use. (Dome side up, push in place so the four prongs are visible on the bottom of the reservoir.)
• Reservoirs can also be hand washed with warm soapy water.

The reservoir is top-rack dishwasher safe.

Step 3: Clean the internal parts.

• Based on your model, mix 1-2 tablespoons of white vinegar with 16 ounces of warm water.
• Run this solution through the unit until the reservoir is empty.
• Rinse by repeating with a full reservoir of clean warm water.

Mix white vinegar with a full reservoir of warm water and run the solution through the unit.

Step 4: Clean the flosser tip.

• Remove the tip from the unit using the eject button.
• Soak the Water Flosser tip in a container of 2 parts water, 1 part hydrogen peroxide or white vinegar for 5 minutes.
• Rinse the tip under warm water.
• For maximum effectiveness over time, we recommend replacing Water Flosser tips every 3-6 months. The tips can become clogged and/or affected by mineral deposits.

Soak the flosser tip in vinegar/water mixture for 5 minutes.

Complete this process every 1-3 months to ensure optimal performance.

Waterpik® cordless models are shower safe.

The most common reason for little or no water flow is a clogged jet tip. You can troubleshoot this condition by removing the jet tip and observing if water bubbles up from the top when the device is powered on.

To remove the tip, press the Tip Eject button (refer to your owner's manual if needed).

To clean the tip, soak it in a container of hydrogen peroxide or white vinegar for 5-7 minutes. Rinse the tip under warm water.

Mouthwash or other recommended antibacterial solutions can be used in our Water Flossers.

We recommend using no more than a 1:1 ratio of solution to water. After using additives, run at least one-half reservoir of plain water through the unit to flush the water pathway.

Do not use mouthwashes or additives that contain iodine, peroxide, baking soda, or water-insoluble concentrated oils (such as Tea Tree Oil). Use of these items can reduce the product performance and will shorten the life of the unit

Do not use a salt/saline solution in any handheld cordless unit. If additives are being used, it is highly recommended that the cleaning procedure is done at least once a month.
