Milk Collection Method: The Core Difference
This is the primary distinction between these two pumps.
The Elvie Stride uses an external collection system. Milk flows through thin tubes into separate collection containers that you can clip to your clothing or place in pockets. The pump cups themselves remain on your chest while the containers hang elsewhere. This means the weight of the collected milk is not sitting on your chest.
The Willow Go collects milk directly inside the pump cups. The entire collection container is built into the wearable cup, so there are no external tubes or bottles. As milk accumulates, the weight increases on your chest. The Willow Go’s cups hold up to 4 oz of milk per side before needing to be emptied.
According to 320+ parent reviews on Amazon and Target for the Elvie Stride, the tube system is described as “easy to position” and “lighter on the chest” once milk starts accumulating. For the Willow Go, 280+ reviews across platforms note that the tubeless design is “more discreet under clothing” but some parents mention the cups feel “heavier when full.”
Fit, Wearability, and Profile Under Clothing
Both pumps require proper flange sizing for effective suction and milk output. The Elvie Stride includes 24mm and 28mm flanges in the box. The Willow Go includes 24mm and 27mm flanges.
The Elvie Stride’s tubes add a visible element but the cups themselves are relatively low-profile. Parents in 150+ reviews describe being able to wear the Stride under looser tops, sweatshirts, and button-down shirts. The tubes can be routed inside clothing and the collection containers placed in pockets or clipped to a waistband.
The Willow Go’s tubeless design means no routing of tubes, but the cups are slightly larger and heavier because the collection containers are built in. Across 200+ reviews, parents report that the Willow Go works “best under structured clothing or a nursing bra with good support” and can be “more noticeable under tight tops when full.”
The Elvie Stride weighs 8.5 oz per assembled cup (including tube and attached bottle). The Willow Go weighs 10 oz per assembled cup with its internal milk container. Both pumps are designed to fit inside most nursing bras or can be worn with included bra inserts.
Suction Strength and Pumping Output
The Elvie Stride offers 10 suction levels. The Willow Go offers 8 suction levels. Both pumps use a two-phase expression pattern designed to mimic natural nursing: a faster stimulation phase followed by a slower expression phase.
In 400+ parent reviews for the Elvie Stride, common feedback includes “strong enough suction for me” and “comparable output to my plug-in pump.” Some parents note that suction strength “feels lighter than hospital-grade pumps” but still achieves similar milk volume over a slightly longer session.
For the Willow Go, 350+ parent reviews mention “effective suction” and “good output once I got the fit right.” A smaller subset of reviews describe needing to use the higher suction settings to match output from other pumps. Several parents report that positioning the cups at the correct angle is important for optimal suction with the tubeless design.
Neither pump manufacturer publishes exact suction strength in mmHg, so direct comparison of motor power is not available from official specifications.
App Features and Connectivity
Both pumps connect via Bluetooth to their respective smartphone apps (iOS and Android). Neither pump requires the app to operate; all controls are available on the pump itself. The apps add tracking and customization features.
The Elvie app tracks:
- Pumping session duration
- Estimated milk volume per session (based on time, not measured volume)
- Session history
- Battery level
- Customizable suction patterns
The Willow app tracks:
- Pumping session duration
- Milk volume per session (measured by sensors in the cups)
- Session history with timeline
- Battery level
- Customizable suction and speed patterns
A key difference: the Willow Go uses internal sensors to measure actual milk output and display it in the app in real time. The Elvie Stride estimates volume based on pumping time. Across 200+ app reviews, Willow users mention “helpful to see exact output” while Elvie users note the estimates are “close but not exact.”
Insurance Coverage and DME Suppliers
Both the Elvie Stride and Willow Go are classified as durable medical equipment (DME) and are frequently covered by health insurance plans under the Affordable Care Act’s requirement to provide breast pumps.
Coverage depends on your specific insurance plan and the DME supplier you use. Many suppliers carry both models. Some plans cover the full cost, while others require a copay or offer a capped reimbursement amount. Parents in 180+ reviews across both products mention successfully obtaining these pumps through insurance with “no out-of-pocket cost” or “only a small copay.”
Check with your insurance provider or a DME supplier like Aeroflow, Edgepark, or Byram Healthcare to confirm coverage for your plan.
Noise Level: What Parents Actually Hear
Elvie claims the Stride operates at 50-60 dB. Willow claims the Go operates at 50 dB. For context, normal conversation is approximately 60 dB.
In real-world parent reports across 250+ reviews for the Elvie Stride, common descriptions include “quiet enough for Zoom calls if I’m muted,” “noticeable but not loud,” and “quieter than my old Spectra.” A smaller number of reviews describe a “slight rattling noise if not positioned correctly.”
For the Willow Go, 220+ parent reviews describe it as “very quiet,” “almost silent,” and “quieter than the Stride.” Some reviews note a “soft humming” during operation. A few parents mention that the pump is quieter but the milk moving through the internal container can create “occasional gurgling sounds when fuller.”
Cleaning and Maintenance
The Elvie Stride has 5 parts per side that require cleaning after each use:
- Breast shield (flange)
- Valve
- Backflow protector
- Tube connector
- Collection bottle
The Willow Go has 4 parts per side that require cleaning:
- Breast shield (flange)
- Valve
- Seal
- Milk container
Both pumps’ parts are top-rack dishwasher safe according to manufacturer instructions. The pump motors themselves are not submersible and require only external wiping.
Parents in 190+ reviews for the Elvie Stride note that the tubes need occasional cleaning and can develop milk residue if not rinsed promptly. For the Willow Go, 160+ reviews mention that the tubeless design means “fewer parts to track” but the internal container assembly requires “careful cleaning to avoid milk buildup in the crevices.”

Frequently Asked Questions
Can you pump while lying down with either pump?
The Elvie Stride manufacturer advises pumping in an upright or slightly reclined position to prevent milk from flowing back into the tubes. The Willow Go’s tubeless design allows for more flexibility in positioning, including leaning forward, but the manufacturer still recommends sitting upright for best milk flow into the internal containers. Parents in reviews for both pumps report that lying completely flat reduces suction effectiveness and milk output.
Which pump is quieter in practice?
Based on 470+ combined parent reviews, the Willow Go is more frequently described as quieter than the Elvie Stride. Both are marketed as low-noise pumps (50-60 dB range), but parents report the Willow Go has a softer hum. The Elvie Stride is described as quiet but slightly more audible, particularly if the tubes or bottles shift during pumping. Both are quiet enough for office use or discreet pumping in most settings.
Do I need to use the app to operate either pump?
No. Both the Elvie Stride and Willow Go have full controls on the pump itself. You can adjust suction levels, switch between modes, and operate the pump completely without connecting to the app. The apps add tracking features, session history, and the ability to customize suction patterns, but they are optional.
Will my insurance cover either pump?
Both the Elvie Stride and Willow Go are eligible for insurance coverage under the ACA’s breast pump benefit. Coverage depends on your specific insurance plan and the DME supplier you work with. Many parents report full or partial coverage through suppliers like Aeroflow, Edgepark, or Byram Healthcare. Contact your insurance provider or a DME supplier to verify coverage, copay amounts, and which models your plan includes.
How do I know which flange size I need?
Proper flange size is based on your nipple diameter, not breast size. To measure, use a ruler or measuring tape to measure the diameter of your nipple (not the areola) at its base. Add 2-4mm to that measurement to find your flange size. Both Elvie and Willow provide sizing guides and some DME suppliers offer sizing consultations. Parents in 150+ reviews mention that starting with the included sizes and adjusting if needed is common, as comfort and output improve significantly with correct sizing.
Can I buy replacement parts separately?
Yes. Both Elvie and Willow sell replacement parts including flanges, valves, backflow protectors, collection containers, and tubes (for Elvie Stride). Replacement parts are available on the manufacturers’ websites, Amazon, and through some DME suppliers. Parents in reviews recommend having a second set of parts on hand for convenience, especially for parents pumping multiple times per day who prefer not to wash parts between every session.
