Willow vs Spectra 9 Plus: What's the Difference?

Buying a breast pump can feel exhausting and, frankly, overwhelming! With so many good options available, it can feel impossible to know which is the perfect fit for you.

To help make the decision easier on you, we are comparing some of the top brands against Willow Pumps!

Today: Willow 3.0 and Willow Go vs. the Spectra 9 Plus.

Here’s the TLDR:

• Willow 3.0 provides 360 degree leak-proof mobility; Spectra 9 Plus is hands free but not meant to be used bending over.

• Willow 3.0 and Willow Go are wireless, tubeless, and fit entirely in-bra; Spectra 9 Plus offers the option to purchase container cups attached to an out-of-bra pump by tubes.

• Willow offers a mobile app (compatible with Apple Watch) to monitor and track pumping sessions; Spectra does not.

• Willow 3.0 and Willow Go have milk collection options. With Willow Go, you can choose either 5 oz or 7 oz milk containers. With Willow 3.0 you can choose from ready-to-store milk bags or reusable containers. Both Willow 3.0 options hold 4 oz. Spectra 9 Plus offers the option of pumping into bottles or purchasing collection cups that hold under 8 oz per cup.

One of the best features of a wearable pump is the ability to move around while pumping. While every wearable pump offers more mobility than a traditional pump, there are ranges of wearable pump mobility.

Willow 3.0 provides 360 degree leak-proof mobility, meaning you can pump in any position: laying down, bending over, you name it! Better yet, the pump won’t leak either! The 100% leak-proof capability requires the ready-to-store milk bags. Moms love the milk bags because you won’t spill a drop, and they’re so easy when pumping on the go. You don’t have to worry about transferring milk. You can pop them right in your bag, cooler, or freezer spill-

Willow Go's fully in-bra design allows you to pump discreetly and efficiently, while remaining upright (generally 45° mobility without leaks)Moms choose Willow Go for– you guessed it…pumping on the go, without requiring the 360° leak-proof mobility Willow 3.0 provides.

Spectra 9 Plus allows you to pump hands free while multitasking. If you choose to buy the hands-free bundle, you will get the Cara Cups that can be placed in your bra. Otherwise, you would pump into bottles like a traditional pump.

While the cups are hands-free, they are connected to the pocket-sized pump by the traditional breast pump tubes. The cups are not meant to be used when bending over, as milk can spill out and suction can be lost.

Remembering to keep your pump charged is one of the biggest shifts from using a traditional pump. The last thing you want to happen is to sit down to pump and realize you haven’t charged your pump!

A good pump makes all the difference in your pumping experience.
