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

I can’t praise this pump enough. It has strong suction, it is comfortable, it is easy to clean, its parts seem like good quality, there are multiple flange sizing options, it is pretty quiet, it keeps a charge really well, it is extremely portable, the app is so helpful and user friendly with lots of combinations to customize your pumping session, and the heating feature is great for someone with slow milk flow. I have consistently pumped around 2 more ounces than with my old pump.

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!

MAMAS. Yes hands down this is the pump. It’s expensive but entirely worth it. I’ve always gotten free pumps through the state my last 3 pregnancies, but I chose to upgrade from my wired Medela swing maxi, and omg such an amazing experience so far to get something this nice. Works amazing, and I’m already pumping an extra oz or 2 since I switched YESTERDAY. has multiple setting for suction and I’m the type that NEEDS a decent amount of suction and it does exactly what I want. The heating effect is also so nice, feels like my boobs are at the spa lol if you’re skeptical don’t be. 10/10 love this pump. Beautiful!

This wearable pump has changed my entire pumping experience. The only reason I can’t give it five stars is because of the occasional leaks. I’ve tried lifting my toddler out of her car seat while wearing them and the seal ca pop. I am also a busty mom and I feel like I needed to use even bigger nursing bras to hold them place. I do think they are great quality. The app makes it easy to customize your pumping experience. The warming feature is a plus, but honestly a cold pump from the fridge just helped me stay awake during nighttime sessions. The charging case is also great to have to keep everything together and store when not in use.

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.

I’ve used the spectra, momcozy S12, ameda glow and now this pump. This one is by far my favorite. Spectra is bulky and we’re taught it’s “the primary pump”. Ignore that! The spectra is bulky and cumbersome. The momcozy is great but is a tad bulky with the motor on top and has no extras to it. The ameda leaks like crazy — drove me nuts! This one draws more and feels better! The heat is amazing, the texture of the cup feels so much better and the app is pretty intuitive. I love the gentle mode. And I love that there is more than one profile to use during the session depending on the desired outcome. Seriously, best pump! And it doesn’t leak! That’s my favorite part. Great output, feels great, no leaks, quiet, and high quality!

I got this pump after seeing others rave about it online. I have the momcozy m9 and the Spectra S1 but mainly use the portable pump for sanity purposes and not wanting to be stuck to tubes. My m9 motor stopped working and I while waiting for a new one from customer support, I really needed another hands free pump asap so decided to get another one. I was between the Willow 360 and this pump but ultimately decided to go with the eufy S1 for the warming feature since I use the fridge hack and HATE having to either put on the flanges cold or wait for them to warm up. Let me tell you, the warming function is a game changer. I think it’s also helped with my output. I’m not a big supplier so every ounce counts. I also love that the machine doesn’t automatically start pumping when turning it on. You have to press the power button one more time to get it started. This is important for me because I like to start at a lower setting and gradually build up. The pumps usually save your previous settings so if I’m at a really high setting to end and don’t adjust it, then my next session starts out painful. I didn’t think I would care about this, but I love the charging case! I don’t have to have all of these cables on my nightstand anymore and it’s good to have traveling. Plus, I feel like the charge doesn’t last as long as advertised (mine only lasted about a day), but that might be because I use the warming feature so frequently and sometimes forget to turn the pump off after a session. I love that it converts between oz and mls. Something small but it’s a nice touch. There are some issues that I don’t like. For me, these are minor issues and just more annoying. I would get the pump again just for the warming feature alone. -The major annoyance is that when I sync the pumps on the app, it’ll start off at the same rhythm but for some reason starts to go off as time progresses. Also, I’ll frequently have one still in simulation while the other one has moved on to express mode but that doesn’t make sense why it would do that since they SHOULD be doing the same thing. It’ll show on the app that my right pump has progressed a lot farther than the left side even though the time is the same. I thought maybe it’s an app glitch but even if you don’t sync it and you manually start it on the pump itself, it still has the same issue. The only way I’ve gotten around the rhythm issue is by manually changing between expression and stimulation. -There’s no timer on the actual pump. You have to rely on the app in order to know how long you’ve been pumping. -The pump itself easily tips over and the milk spout is right next to the charging port and the buttons so it may get damaged over time if you’re not careful. -The measurement on the cups are off. It’ll say like 0.5oz but when I actually measure it out into my Medela storage containers, it’ll be more like 1-1.5 oz. -When your session is done, you can type out the amount of milk as exact amounts, but if you type it in later or have to edit the amount, then you can only scroll in increments ( for oz it’s by 0.3’s and for mls it’s by 5’s). I’ve only been using this pump for two days but it’s my favorite pump so far. I’m probably going to use this as my main pump. :) Edit: Removing a star for case design. I do like the pump, but finally went out this week and realized you can’t put the pump inside the case without removing the protective flange cover because there’s a bump in the middle… what’s the point of having a flange cover if you can’t use it at all times?

I apologize in advance for this long review! Also for my grammar/typos…. I’ve had this pump for two days so this review is obviously only based off two days of use. I exclusively pump. I have a 3 month old and a 3 year old so I’m constantly moving. I needed a wearable comfortable pump. This is my second wearable pump the first one was cheap and got the job done for the most part but it only had two modes. I have been researching other wearable pumps and these wearable pumps are an investment. I bought the Eufy on prime day which was an amazing deal. I was sold on the Eufy because of the heat setting. I’m very sensitive like I have to have the suction low but I’m also an over producer. Anywho I love this pump!! There is an app to connect it to your phone and you can control it from there or the pump itself. You can sync both of them or have separate modes. You can have an auto shut off! Whatever setting you leave off on will be the one that is suggested when you turn it back on. Also in the app you can track your ounces you do have to manually put them in which isn’t bad. I absolutely love the heat setting it’s very comfortable and you can have it automatically shut off on a timer too, I’m a hot person and this doesn’t add to it or make pumping unbearable. Now moving on to putting it together and taking it apart. Once you get the hang of it man it’s super easy! I haven’t spilt any of my milk while taking it apart which I’m thankful for because we all know it’s hard work making it anyways we don’t want to waste it! So I take my fingers and pull by the spout in the opposite direction from the motor. Someone pulling them in two different directions at the same to get the magnet to come apart once I fill that it’s not connected anyone I pull the motor off. I’m sure I’m not explaining it correctly but once you get it down it’s so easy! The other parts are super easy to take off and put back on, also very easy to clean all parts. Now I’ve noticed when putting the flange back on the milk container easier to push the sensor in place and then push the center of the flange where your nipple goes in to place first before doing the rim. Just somethings I’ve found easier for me.! Oh also when pouring your milk always have the flange facing up not down if you do you’ll lose some milk! I’ve caught myself trying to do it that way and then I remember! When I say I collect every drop EVERY DROP comes out again you’ll get it down with what works best for you! One last thing the charging cord it’s just one with a split end with TWO chargers on it. Oh I also charged it before my first use. I didn’t charge it at all one day and I pumped 5 times in one day my sessions were 20 minutes a piece. The next day I pumped with it two more session and then I charged it. I felt like it holds a good charge. I’m sure I’m leaving so much out but again it’s amazing!! I’m so sorry that I rambled I hope this helps someone else. **Update 8/30/24 I still love this pump! I use it 3X a day! I absolutely love not being tied down when I’m driving or working! I’ve literally pumped everywhere! Which makes life easier when you are constantly on the go! My family and coworkers don’t even hear it most of the time because the surrounding noise is louder. I don’t have any complaints other than I wish it held more ounces but I can’t even fault them for that.
