eufy Security Heated Wearable Breast Pump S1 Pro, Slim Hands-Free with Industry-Leading HeatFlow Tech, Wireless Charging Case, App-Controlled OptiRhythm, Hospital-Grade Suction, in-Bra Use

Updated: 12/25/25 This is my new favorite pump! I reach for it just as much as my Baby Buddha around a month after purchase. I’ve loved using it during MOTN feeds, as I can get my overnight pump in without waking her up. I’ve also used it at work regularly, because I can keep my office door open and attend meetings. I have to keep my office door closed when I use my Baby Buddha, which forces me to keep my office door closed 60-90 minutes per day to pump. I work in an environment that gets regular foot traffic, so being able to keep my door open is a bonus! My Baby Buddha pump is my go to if I am engorged or need to be 100% sure I am empty, or I have the time and privacy to use it. This pump is my go to on my commute into and home from work, and discreet pumping overnight or in public. The suction is great, the speed settings are great, and it does a pretty good job of emptying me. I am so glad I purchased this pump! ——————— I’ve only had this pump half a week and used it over a dozen times, but I absolutely love it! I have continually reached for it over my Baby Buddha motor pump. Pros: - It has a heating feature which can help with expression. - Very easy to change suction and speed settings for your comfort. Even when I am using higher suction and speed settings, the pump is super comfortable and is never painful. - I found the pump very easy to assemble and disassemble. There wasn’t much of a learning curve, and there are only pump four parts involved in assembly, two of which take a fraction of a section to install (diaphragm and duckbill valve). - The app comes with pre-made rhythms. I love the “max output” and “natural” rhythms and get the best output with them. - I have great output comparable to when I use my Baby Buddha motor pump. - The silicone flanges are very comfy. I’ve had no difficulties aligning everything and getting a solid seal. - I can lift my arms and move normally without worrying about breaking the seal. It has made caring for my infant and pumping on a schedule to be very easy. I can easily hold my baby and pump without worrying about dislodging my seal. - The pump is VERY quiet and the pumps are not too large that it’s distracting. I wore it at a public event recently. The event noise easily drowned out the pump sounds, and the pumps didn’t look unrealistically bulky under my shirt. - The charging case gets you a few charges on the go. - All parts can be dried and sterilized in my Baby Brezza dryer/sterilizer. —— Cons: - I have spilled milk a few times, because you need to make sure there is a tight seal with the collection cup and flange when pouring. It helps to have the flange side pointed up to prevent leaks. - The pump can’t be plugged in while using, so if it’s dead, you need to wait for it to charge. A full charge takes a little less than 2 hours. - Replacement parts are a bit more expensive. I just bought an extra pair of collection cups, a pair of flanges, and a pair of diaphragms to have on hand and spent $72 through the Eufy website (with a coupon, original total was around $109). - Quiet, but not silent. Can definitely hear it in lower volume settings. But, it’s not so loud that it is horrendously distracting. - The heat feature will drain your battery faster. I was still able to get multiple pumps off one charge. But if you depend on the heat setting to get much better output, you need to account for more frequent charging. I don’t think you could get a day of consistent pumping with heat out of one charge, if you pumped for 20-30min at a time. —— I am so happy with my purchase. I weighed the pros and cons of multiple wearables, and landed on Eufy. I love my Baby Buddha, but the standard flanges don’t allow for freely moving in public, don’t allow for my to easily hold and care my infant, don’t align with a consistent pumping schedule as a working mom, and don’t allow me to pump at work with my door open. This pump has been a game changer and allowed me much more freedom. Before it was very difficult for me to pump regularly day and night with the Baby Buddha flanges. Now I can throw this wearable on and live life as usual, which has made it easier for me to consistently stick to a pumping schedule. My pumping output has nearly doubled in half a week due to this. I will definitely be able to keep up my goal of pumping 6-8 times per day, thanks to this pump. I’ll update this review if anything changes in the coming months. But I have been extremely happy so far!

Love this wearable pump, definitely worth the money! The heating feature is so worth it and it’s as close to hospital grade suction as you can get with a wearable so I get good output! And I love that I can use the app to control the settings.

As a mom juggling a newborn and other kids, the Eufy breast pump has honestly been a game changer for me. The biggest advantage is the freedom it gives—you’re not tied down to one spot. I’ve been able to pump while driving, doing chores, and even feeding my baby a bottle at the same time, which is huge when you’re managing multiple kids and trying to stay on schedule. In terms of performance, I will say my Spectra pump does yield slightly more—about 0.5 to 1 ounce more per session collectively—but for me, the convenience of the Eufy more than makes up for that difference. Being able to move around and multitask is invaluable, especially in the early weeks when feeding sessions are frequent and time-consuming. Comfort-wise, I’ve found that it really depends on having a well-fitting bra. When everything is positioned correctly, it doesn’t feel too heavy and can actually be quite comfortable—sometimes I barely notice it’s on. Other times, it can feel a bit uncomfortable, and I’m still trying to figure out what causes that variation (likely positioning or flange fit). That said, I really appreciate that Eufy includes nipple measurement and flange sizing guidance—this is something all pump brands should offer because it makes a big difference. The pump is also impressively quiet, which is great if you’re around sleeping kids or trying to be discreet in public. Cleaning is straightforward and easy—the parts come apart quickly and don’t feel cumbersome to wash, which is a big plus when you’re already short on time. Another standout feature is the app integration. It includes built-in programs, including options for power pumping, which is incredibly helpful if you’re trying to build or maintain supply. The heating feature is also a nice touch and adds to the overall comfort. I highly recommend getting the portable charging case—it makes a big difference for on-the-go use and keeps everything organized in a compact, easy-to-carry way. Overall, this pump is a must-have for working moms or anyone exclusively pumping. While it may not extract quite as much as a traditional hospital-grade pump, the convenience, mobility, and thoughtful features make it absolutely worth it.
