What's New for Generation 3?

Willow Pump Generation 3

Re-engineered from the inside out, our Generation 3 smart pump offers more comfort and control – and helps you get more milk.

  • Slower, softer pumping rhythm designed for comfort
  • Smart Suction technology adjusts based on your preferences to increase output (no need to press a button)
  • Plus, a new app exclusively for Generation 3 with step-by-step onboarding and personalized pumping tips

  • Everything works inside the pump and inside your bra, with no external tubes, cords or dangling bottles to hold you back.
  • Milk flows into the spill-proof disposable collection and storage bag or reusable container inside the pump (container accessory sold separately).
  • Smart, proprietary technology responds to your body and maintains suction similar to a baby, enabling true mobility without spilling a drop.
  • Lie down, bend over, play with baby, take a conference call… pump wherever the day takes you!
  • Spill-proof in any position. Willow is the only breast pump that’s totally enclosed and spill-proof in any position with self-sealing milk bags.
  • Smart Suction Technology adjusts based on your preferences to increase output (no need to press a button).

  • Quiet pumping. Pump wherever the day takes you— with no disruptions.
  • In-bra pumping. No need to undress or buy new bras—your regular maternity or nursing bra is perfect for Willow!

Rough start but amazing ending!

I had a rough start with my left pump. Error messages kept coming up. After 2 replacement pumps and with great response from customer service, I have had the most amazing experience. I was strictly a pump-only mom for my 2 girls. Now I have my son and this product has been a game changer! Totally worth every penny! With 2 active toddlers... I must say that this has changed the way I feel about pumping. I can pretty much do anything around the house or anywhere really and still tend to my babies while I’m pumping!!

Love it

Totally useful. I use it around the house and while driving or running errands. I love the spill free bags and reusable containers but with the containers I don’t bend over to prevent leaking. Totally great suction and volume. It’s comfortable and easy to use and simple to clean.

Willow is WORTH the money!

I had my first born two weeks ago and I had anticipated on exclusively breastfeeding. Well, you know how babies are… that being said my little one won’t latch. After debating what is best for us, I decided I will exclusively pump. I had been using my spectra pump which made me feel extremely limited in what I can do. I don’t have the time to sit for 20-30 min plugged into the wall! So I looked into wearable pumps and I was recommended Willow. Let me just say, this has been a game changer. I can get so much done around the house AND take care of my baby, all while pumping away. It’s so quiet and gives me 360° mobility. Not only that, but it’s so easy to clean. The app is user friendly as well. Honestly, Willow has taken a tremendous amount of stress off of me the last few days. I can confidently go into my pumping journey thanks to Willow.

Amazing product!

I struggled with postpartum depression when I first had my daughter and thought I might have had to give up on breastfeeding and pumping because I couldn’t stand being tied down to a pump that I needed to hold up to my body and plug into the wall. The willow LITERALLY saved my breastfeeding journey and I am forever grateful. It’s also the only pump I’ve tried that empties my breasts fully and I’ve been able to increase my supply with this pump!
