FAQs

What makes Willow Go™ different from traditional breast pumps?

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.

What are the differences between Willow® 3.0 and Willow Go?

Willow 3.0 offers complete, leak-free mobility when pumping with our Spill-Proof Milk Bags. With its gravity-defying continuous latch suction technology, you can pump in any position, from bending over to lying down. Willow Go doesn’t offer as full of a range of motion, but offers the same completely in-bra design and lets you pump totally hands-free and untethered. Willow Go’s “tug and release” suction technology is comparable to traditional pumps and other wearable pump brands.

Willow 3.0 offers more milk storage options. It’s compatible with Spill-Proof Milk Bags and reusable Containers, while Willow Go offers Containers only.

Both pumps are app connected, but Willow 3.0 offers smart pumping that tracks volume in real time and automatically records your session. Check out our comparison page for more, or take our pump quiz to decide which pump is right for you.


Is Willow Go covered by insurance?

Some women are able to obtain full or partial reimbursement for their Willow Pump and accessories through insurance. Use our Insurance Verifier to check your coverage and purchase your discounted pump.

As you navigate through this process, start with our guide on how to get a breast pump covered by your insurance. It gives you all the questions that you need to take to your insurance provider to understand how to obtain coverage and the costs involved.

Can I use my HSA/FSA?

Yes, you can. Simply pay for your breast pump and accessories using your FSA/HSA debit card at checkout, or pay with another credit card and submit your receipt to your plan administrator for reimbursement.

Do you offer financing?

Yes! We partner with Affirm to offer split pay and installment payment plans for Willow pumps. Learn more about our financing options.

How many ounces does Willow Go hold?

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).

What do you mean by hospital grade suction strength?

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 3.0 and Willow Go have a wearable, in-bra design, with a suction range and strength that is comparable to traditional double electric and hospital grade pumps. Willow 3.0 offers a proprietary continuous latch suction and unique pumping waveform with up to -245mmHG maximum suction. 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.

Which bras do you suggest with Willow Go?

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 both Willow 3.0 and Willow Go.

What smartphones does the Willow Go App support?

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.

How do I charge Willow Go?

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.

Does Willow Go have a warranty?

Yes! Willow Go is covered under a 12 month warranty from the purchase date. Accessories - all replaceable pump parts including but not limited to flanges, containers, diaphragms, duckbills, chargers and sizing inserts- are covered under a 90 day warranty. Please review our warranty policy.

Since breast pumps are single-user devices, use by more than one person, including purchasing second hand, will invalidate the warranty. Please keep your original proof of purchase from onewillow.com or an authorized retailer as it is required to exercise your warranty.

Can I return Willow Go?

Breast pumps and accessories are regulated as single-user products, and cannot be returned once the safety seal has been broken. See our returns policy.

• You can return an unopened Willow Pump within 60 days of the purchase date. If you decide to return your unopened pump or accessories, you must contact us to start the return process and to obtain a RMA number. Please review our return policies.

• Only products purchased from onewillow.com may be returned directly to us. For products purchased from our retail partners, please follow their instructions.• Willow pumps are single-user medical devices and returns must be new, unopened (no seals broken), unused, and in the original packaging.

Best Choice we made

I’ve been eyeing Willow products before thinking of having my first. I have a traditional pump but didn’t want to take it everywhere we may travel to so we decided to purchase the Willow go, best decision ever!

I wish I had bought this sooner

I got this pump too late in the game. I am in the process of relactating after 6 months postpartum. I had to return back to work 2 months after I had my baby and pumping at work with the pump I had was almost impossible. So I stopped pumping. But if I had known about Willow go, I would have bought it right away and not stopped pumping. It’s perfect for working moms. Gives me full freedom to do work while pumping. Not just work but it’s perfect if you’re traveling or on the go. It fits perfect in my purse. Also it fits good in my regular bra and the aeroeflow were so generous to send me tons of milk storage bags. It has great suction and batteries seem to last for a good amount. I am in 3rd week of re-lactation 90% on this pump, I get a drop in each breast every session.

So worth it

As someone who primarily nurses, I’ve still found the willow go to be a HUGE game changer. My son is the type of baby that won’t let me put him down without a fuss and won’t stay asleep without me, but also doesn’t eat a ton at night feeding/early morning, so I use the willow on one side while he nurses the other and it’s been PERFECT for that! I’ve also taken it on road trips with us, and will pump using them in the car and pour the fresh milk into a bottle for him, to make things a little more efficient time wise.

I’ve had trouble with pain and output with other pumps, even using the correct flange size, but the willow is really comfortable for me! I’m really great full to have found a pump that works with my body in addition to its convenience.

The two issues I’ve had with the pump:

1. Sometimes the suction does not work properly in one of my pumps, so I take it apart and put it back together again and so far its magically worked after that each time. Not a huge deal, but a bit annoying. It’s an issue I’ve had only a few times so far, but I could be really frustrating if it continues.

2. Pouring the milk out of the containers is not the easiest. I often find myself spilling a little, which is not a huge deal to me either, but could be very upsetting to someone who needs every drop.

Overall, I LOVE the pump despite those few flaws, but things that could make a difference to someone.

Busy busy lady!

I am such a fan. I’m a busy mom trying to stay a breast feeding mom. Pumping hands free allows me to connect more with my life, my other kids life. I’ve had hands free pumps before. But this is by far the best! No tubes to pop out. Charging is easy, washing the parts are so easy! I am such a fan. The Bluetooth part helps me know how long I’ve had the pump on. Sometimes the Bluetooth won’t connect however that is probably more my phones problem than the Willow. I do wish it came with bags to save milk. Or a carrying case. I’m still working on how I am taking it on the go.

At first it was a bumpy ride, but now I love it!

At first I needed 2 replacements and was getting very frustrated... But customer service did great and since then it's been smooth sailing! I LOVE this pump! Works so well, comfortable (the 3.0 HURT me), and great output! Plus since the software updates, I can do 6 pumps on each charge per side... I wear these driving to/from work and discreetly at work as well and I am confident these SAVED my pumping journey. I EP and really really want to get to 12 months! This is my first baby. Thank you, Willow! I've even bought the cute little bag for this, love the color, the style of the pumps and the bag - everything!!!
