- 1 Waterpik Cordless Pulse Water Flosser Unit
- 2 Waterpik Classic Jet Tips
- 1 USB-C to USB-A Charging Cable
Setup
- Initial Charge: Before first use, fully charge the unit. Connect the USB-C end of the charging cable to the port on the flosser and the USB-A end to a compatible wall adapter (not included) or USB port. The recharge indicator light will show charging status. A full charge provides up to 4 weeks of use.
- Attach Tip: Insert a Classic Jet Tip into the center of the handle until it clicks into place. To remove, press the tip eject button and pull the tip away from the handle.
- Fill Reservoir: Open the flip-top lid on the reservoir. Fill the reservoir with warm water. The reservoir has a 6oz capacity, providing up to 45 seconds of flossing time. Close the lid securely.

The easy-fill reservoir allows for quick and convenient refills, ensuring continuous flossing without interruption. It holds enough water for a thorough cleaning session.
Operating Instructions
- Select Pressure Setting: The device features two safe and effective pressure settings: low and high. Use the power switch to select your desired intensity. First-time users should start with the low setting and gradually increase as comfortable.
- Positioning: Lean over a sink. Place the tip in your mouth, aiming it along the gumline at a 90-degree angle. Close your lips enough to prevent splashing while allowing water to flow from your mouth into the sink.
- Begin Flossing: Turn the unit ON. Guide the tip along your gumline, pausing briefly between teeth. Floss both the inside and outside surfaces of your upper and lower teeth.
- Waterproof Use: The Waterpik Cordless Pulse is waterproof and can be used in the shower for added convenience.

The ergonomically designed non-slip hand grip ensures comfortable and easy control during flossing, enhancing precision and effectiveness.
Maintenance
- Empty Reservoir: After each use, empty any remaining water from the reservoir. The reservoir is top-rack dishwasher safe for easy cleaning.
- Clean Unit: Wipe the exterior of the unit with a soft cloth. Do not immerse the main unit in water.
- Tip Replacement: Replace Classic Jet Tips every 6 months, or sooner if they show signs of wear.
