My Willow Go Review
After testing a wide range of breast pumps over the years, one thing has remained clear—every mom’s needs are different. While some pumps prioritize power or app features, others lean into portability or simplicity. The Willow Go tries to balance all four, offering a hands-free experience with strong suction and minimal setup.
That’s why in my Willow Go breast pump review, I’ll walk you through the key features of this wearable pump and break down the pros and cons, so you can decide if the Willow Go is the right fit for your lifestyle and pumping routine.

What I Love About the Willow Go
For a wearable pump, I think the Willow Go includes several thoughtful features that make it a solid option—especially for those who value flexibility and simplicity.
As with any wearable breast pump, the Willow Go has no tubing or external motor, so it fits directly into your bra. It is longer than some of the other wearable breast pumps, but this also means that it has a slim profile making it quite discreet, especially when coupled with the app integration.
The suction performance is also pretty good for a wearable. With up to 280mmHg of hospital-grade suction and 15 levels across two modes, it provides more control than many competitors in the same category. The combination of strength and adjustability makes it well-suited for both comfort and output.
The hard silicone flange is a single-piece design available in 21mm and 24mm sizes. While firmer than soft silicone inserts, it’s easy to position and forms a consistent seal. The simplified design reduces the number of parts to assemble and clean, which is a smart design choice for everyday use.
Another feature worth highlighting is the milk collection capacity. The standard 5oz cups are sufficient for most sessions, but the option to upgrade to 7oz collection cups is particularly useful for those with higher output or longer sessions. This extra capacity is a thoughtful addition that not all wearable pumps offer.
And finally, the fact that the Willow Go is top-rack dishwasher safe is a major convenience. Cleaning breast pump parts can be time-consuming, so being able to toss the components into the dishwasher is a huge time-saver and a standout feature in this price and product category.
While it’s not perfect (I’ll cover a few downsides later), the Willow Go is a solid option for a wearable breast pump. You can also see how it compare to other wearables in my Eufy S1 Pro vs Willow Go review!

Performance and Efficiency
When it comes to performance, the Willow Go offers strong, reliable suction in a compact wearable design. It features two pumping modes—stimulation and expression—along with 15 suction levels, which allows for a good level of adjustability despite the simplified setup.
The suction strength reaches up to 280mmHg, putting it in line with hospital-grade pumps and making it suitable for maintaining milk supply across different stages of pumping. While I love customization with the 15 suction levels, I do think that having only 2 modes is a bit of a letdown, especially when you compare it to similar priced pumps like the Momcozy M9. Ideally, it would be great to have a mixed mode or automatic letdown pattern available. That said, the modes are straightforward, controlled directly on the pump or via the Willow App.

Design
The Willow Go features a fully integrated, all-in-one design, combining the motor and collection cup into a single unit that fits directly inside a standard nursing bra. This self-contained structure eliminates the need for tubing, cords, or external attachments, making it a true wearable pump built for mobility and convenience.
Each pump weighs around 370g, which places it on the heavier side compared to some lightweight wearables. However, the weight is evenly distributed, and the rounded profile helps it sit more comfortably against the body. While not completely invisible under clothing, it remains discreet enough for everyday wear, particularly with looser tops or nursing bras with good structure.
The collection cups hold up to 5oz of milk, which is sufficient for most single sessions. For those who pump larger volumes, a 7oz version is available and adds extra flexibility without significantly altering the shape or weight of the unit. The milk is stored securely within the cup, and the design minimizes sloshing or leaking during wear.
One of the key advantages of the Willow Go is its minimal part count. The pump consists of only a few pieces, all of which snap together with a clean, intuitive fit. This makes assembly and disassembly quick, and reduces the chance of losing components—a benefit for anyone pumping multiple times a day.

Comfort
The Willow Go uses a single-piece hard silicone flange that’s built directly into the pump. Unlike pumps that rely on soft silicone inserts, there’s no additional cushioning layer between the flange and the breast, which gives it a firmer, more structured feel during sessions.
While the hard silicone material provides a stable seal and maintains suction well, it may feel less flexible compared to soft silicone options—especially during longer or more frequent pumping sessions. The rigid structure is efficient for milk removal, but may not offer the same level of comfort for users with sensitivity or a preference for softer contact.
Two flange sizes—21mm and 24mm—are included in the box, which covers a fairly standard fit range. However, there are no smaller or intermediate sizes provided, and the fixed nature of the flange design means sizing options are limited without purchasing third-party accessories. This could be a drawback for those who fall outside the included size range or require a more customized fit.
Noise Levels
The Willow Go operates at around 50 decibels, which places it in the mid-range for wearable pumps. The sound is a steady mechanical hum—not overly loud, but noticeable in quiet environments. It’s discreet enough for use at home or in private spaces, but may be heard in very quiet shared settings.
While not as silent as some ultra-quiet models such as Elvie Pump, the noise level is generally easy to mask with ambient sound, making it suitable for most daily routines without drawing too much attention.
User-Friendliness
The Willow Go is designed with simplicity in mind, but there are a few trade-offs to be aware of when it comes to user interface and app functionality.
Unlike pumps with a built-in LED screen, the Willow Go relies entirely on a single button located on the top of the pump for switching modes and adjusting suction levels. While this keeps the design minimal, it also means there’s no visual feedback or on-device display to track settings, time, or session progress. For me this is disappointing as it adds a layer of guesswork during use—especially in low-light or overnight pumping sessions.
The pump does offer a companion Willow Go app, but its functionality is limited. It’s currently only available in the USA and Canada, and even within those regions, it doesn’t allow control of suction levels. Users can switch between modes via the app, but all suction adjustments must be done directly on the pump. Additionally, milk output must be logged manually, and the app lacks features like real-time tracking or session history that are found in more advanced apps.
That said, the overall setup is relatively straightforward. The pump consists of just a few main parts, and the collection unit snaps together easily. The lack of tubing or connectors simplifies assembly, and once familiar with the controls, using the pump becomes fairly intuitive.
Portability
The Willow Go is built for portability, with a completely cordless, wearable design that fits directly into a bra—making it one of the most travel-friendly pumps available. There are no external motors, tubes, or power cords needed during use, allowing for full mobility whether at home, at work, or on the go.
The pump is powered by a rechargeable battery that offers up to 90 minutes of use per full charge, which translates to about three pumping sessions. While this is sufficient for part-time or occasional use, it may not be ideal for exclusive pumpers who need more sessions throughout the day without recharging.
Charging is done via USB, although the device does not use USB-C. A full charge takes approximately 2 hours, and the battery generally holds its charge well between uses. However, there is no charging case included like you get with the Eufy S1 Pro, so users who plan to pump away from home may need to carry a backup cable or power bank for convenience.
Value for Money
For everything that’s included, the Willow Go offers solid value—especially for a hands-free pump with hospital-grade suction in a true wearable format.
Priced around $350 USD, it sits in the higher-range for wearable pumps. And while I don’t think it offers the greatest value in a wearable breast pump, it often goes on sale, and if you can get it discounted I think it makes it a more viable option.
The included components are enough to get started right away, and for those needing more capacity, the optional 7oz milk containers are a helpful upgrade. While the app is limited and battery life is shorter than some, the overall package balances convenience, performance, and design at a reasonable price point.
When you purchase the Willow Go double pump, included in your box is:
- Willow Go Pump Motor Units * 2
- 5oz Reusable Milk Containers * 2
- Flange (21mm and 24mm, depending on selected size) * 2
- Pump Diaphragms * 2
- Container backs * 2
- Splashguards * 2
- Duckbill Valves * 2
- USB Charging Cable * 2
- Instructions for Use * 1
Additional accessories—such as the 7oz containers, replacement parts, and carry bags—are sold separately through Willow’s website.
What I Wish Was Different
I’ve already touched on a few of the trade-offs of the Willow Go, but here’s a quick recap of the areas that could be improved:
- Limited App Functionality: While the pump includes an app, it’s only available in the U.S. and Canada—and even then, the features are minimal. You can’t adjust suction levels or track sessions automatically. Milk output must be entered manually, and there’s no integration for reminders or detailed logs. For a pump at this price point, a more functional app would add a lot of value.
- No On-Device Display: The absence of an LED screen means there’s no visual feedback while pumping. You can’t see your suction level, time, or mode at a glance, which may be frustrating—especially during nighttime sessions or for those who prefer more control over their settings.
- Short Battery Life: With a battery life of just 90 minutes (around three sessions), the Willow Go may need to be recharged daily depending on your routine. While it’s manageable for part-time pumpers, it’s less ideal for full-time or exclusive use.
- No Smaller Flange Sizes: Only 21mm and 24mm flanges are available. Those needing smaller or in-between sizes may have to seek third-party options, which can be inconvenient and add to the overall cost.
That said, many of these limitations are expected for a wearable pump in this category—and the Willow Go still offers strong performance and ease of use overall. But they’re worth keeping in mind to make sure the pump aligns with your specific needs and expectations.
The Verdict
If you’re looking for a hands-free, all-in-one breast pump that’s easy to use and travel-friendly, the Willow Go is a solid option. It combines hospital-grade suction, minimal parts, and cordless operation in a sleek, wearable format that fits discreetly into your daily routine.
While it doesn’t offer the advanced tracking or customizations of some higher-end models, it still delivers where it counts—strong performance, simple assembly, app integration, and a compact design that’s ideal for multitasking. The top-rack dishwasher-safe parts and optional 7oz container upgrade are also standout features that add everyday convenience.
There are a few downsides to be aware of—limited app functionality, no display screen, and shorter battery life—but for many users, these are manageable trade-offs in exchange for the freedom and simplicity the Willow Go offers.
Overall, I think the Willow Go is a solid choice for those who want a wearable pump that’s reliable, discreet, and easy to maintain—without jumping to the highest price tier. It’s especially well-suited for part-time pumpers, working moms, or anyone wanting to pump without cords or compromise.
