Willow Go FAQs
-
Willow Go is unique because, unlike traditional breast pumps, everything works inside the pump, inside your bra—no external tubes, cords, wires, or dangling bottles. This smart, hands-free pump connects to our app for step-by-step onboarding, easy session tracking, and pumping pro tips. Learn more about why Willow or check out our blog post for more information on how Willow pumps differ from manual and electric breast pumps.
-
We know every ounce matters when it comes to pumping and breastfeeding, so we engineer and test our pumps to optimize milk expression and comfort. Willow Go has a wearable, in-bra design, with a suction range and strength that is comparable to traditional double electric and hospital grade pumps. Willow Go offers maximum suction up to -280mmHG. Willow pumps are closed system pumps, just like hospital grade pumps.
While Willow’s suction strength is equivalent to hospital grade pumps, Willow pumps are single-user and have been clinically tested with established milk supply. Consult your health care provider if you are seeking to initiate lactation with a breast pump.
-
Willow Go holds up to 5 oz of milk (10 oz total). If you pump more than 5 oz per side, purchase our 7 oz containers to pump up to 14 oz per session (sold separately).
-
For your best pumping experience, we recommend a full coverage nursing bra that's stretchy and has a flap - no underwires or padding. It should hold the pumps securely in place when fastened. The Willow Perfect Pumping Bra works great with Willow Go.
-
The Willow Go App is available for devices that run the following operating systems:
iOS 14 and higher
Android OS 10 and higher (must support Bluetooth 5.1)
Keep in mind, due to the significant number of different Android device models, Willow® cannot guarantee optimal performance of our pumps across all devices.
-
The Willow Go pump kit includes two USB charging cables which can be used with any standard 5 Volt USB power source. We recommend at least 5 Volt 2 Amp adapters for fastest charging.
