Willow Manuals & User Guides

Saule is a femtech leader dedicated to improving the lives of mothers through innovative technology. The company revolutionized breast pumping with the introduction of the Willow Wearable Breast Pump, the first quiet, all-in-one, in-bra pump designed without external tubes, cords, or dangling bottles. This closed-system design allows mothers to pump completely hands-free and in any position—even lying down—without leaks, granting unprecedented freedom and mobility.

The brand's product lineup includes the Willow 360™ (formerly Willow 3.0) and the Willow Go™, catering to different needs for capacity and spill-proof performance. Willow pumps integrate seamlessly with the Willow App, enabling users to track milk volume in real-time, view session history, and control suction levels directly from their smartphone. By combining medical-grade technology with modern convenience, Willow empowers women to maintain their breastfeeding journey without pausing their lives.

• How do I find my flange size for Willow pumps?

  To find your size, measure the base of your nipple (not the areola) before pumping or at least one hour after. Use the Willow sizing guide or a ruler to determine your measurement in millimeters and select the corresponding flange or insert size.

• What is the "Flip to Finish" technique?

  Flip to Finish is a movement used with the Willow pump to transfer milk from the tunnel into the milk bag or container at the end of a session, ensuring no milk is spilled when removing the pump.

• Are Willow pump parts dishwasher safe?

  Yes, washable parts such as the flange, Flextube, and container components are dishwasher-safe. They should be placed on the top rack. Always consult your specific model's manual for detailed cleaning instructions.

• Can I check my milk volume on the app?

  Yes, the Willow App connects to the pump via Bluetooth to provide real-time milk volume tracking, session history, and suction control.
