eufy Heated Wearable Breast Pump S1 Pro, Charging Case, Hands-Free

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!

This pump is amazing it's been 2 months of use after a failed attempt with a different pump! I normally forget to write reviews but I love it so much! First session I got 5 oz in ~10 mins. I use these probably more fequently than I should since I have a spectra 2, this empties me quicker though. They will help me when going back to work next week for sure, I'm about to order more parts now to help with that transition. They are powerful so play with the setting to help you out the best. The heated feature is nice but I barely use it. Be careful with bending over and you have to watch out for overflow because it happens, make sure you also put the flange together correctly or milk will spill on you. Great design, functionality and fit for a heavier chested person. Love this product and it makes pumping so convenient :) great price also especially if you catch it on sale!

I bought the eufy S1 Security Heated Wearable Breast Pump because I wanted a hands-free pump that would allow me to take care of my baby and get things done while pumping. I was also really interested in the built-in heating feature since I had heard it could make pumping more comfortable and help with milk flow. I was hoping it would be discreet, comfortable, and efficient, and it definitely met my expectations. The pump was easy to set up, and the controls are simple to understand. I love that it fits comfortably inside my bra without feeling too bulky, so I can move around the house while pumping. The heating feature is one of my favorite parts—it provides a gentle warmth that makes pumping much more comfortable and seems to help me empty more efficiently. The suction is strong but comfortable, and I appreciate having multiple suction and stimulation settings so I can customize each pumping session. Another thing I really like is how quiet the pump is. It's discreet enough that I can wear it around the house or while out without drawing attention. The collection cups are easy to pour from, and all of the parts come apart easily for cleaning, which is a huge plus since pumping already involves enough washing. The only small downside is that wearable pumps can hold a limited amount of milk compared to traditional bottles, so if you have a large output, you may need to empty them during longer sessions. It also takes a little practice to get the positioning just right the first couple of times, but once you do, it works really well. Overall, I'm extremely happy with this purchase. It's comfortable, efficient, and has made pumping so much more convenient. Being able to pump hands-free while still taking care of my baby or doing things around the house has been a game changer. I would definitely recommend it to any breastfeeding mom looking for a reliable wearable breast pump.

EDIT: I’m 8 months PP and quite honestly this pump is the one I always reach for now. There’s the diff pumps I have where I use them depending on the setting/place we’re attending but I usually almost always reach out for this pump now. It empties me as much as the spectra (gold model) since my body is used to them now. I think it took at least a few weeks for it to switch since I started to use it way more than the spectra once I worked because they were wearable. I was very surprised! I really had to trust that it was just going to work, it even says that in their instructions you have to just be patient with it. The gentle mode worked for me with the heat - I had to play with the settings BUT now there’s a feature where other people can share their sequence and other settings that you can upload to your app to see if it helps out more. I wouldn’t be able to use them without the legendary inserts though, they are godsend (eufy please make something like this!). I really like the legendary inserts because it’s rubber and the circumferential length of the inserts covers a good amount of surface area to attach to your breast - the pumps really stay in place in my pumping bra since I move all around at work. I also got the plugs for the top so the milk doesn’t go everywhere. I have 4 sets of these so I can use them daily and I started to do the fridge hack at work since it was the easiest for me to do. I believe now they come in a 21mm size too, so I’m really excited to try those flanges too! Also definitely invest in a bottle washer to clean them makes it even more easier to use, I can’t live (mentally) without the Momcozy bottle washer for cleaning them. They clean them soooooo well and I can put two sets of these pump containers in it to clean each time. I hope it’ll work out for anyone taking a chance on these!! Oh also AMAZING CUSTOMER SERVICE!!! I had something I needed from customer service and they were very helpful and attentive and replied very quickly each time I messaged them. That is very rare. Thanks so much!!!! ——————————————————————- LONG REVIEW - Because I feel like with any pump on the market considering how much they cost, they should all have one. I would’ve liked a thorough review compared to most of the other reviews I’ve seen here with all the pros and cons. Or maybe they were just that frustrated they didn’t post here. I was really excited to get this pump as I had been looking really extensively for the past month on what portable breast pump to get. I bought a main plug in pump and was paying out of pocket for this one for work and wanted to make sure it did everything I needed it to do. I’m a health professional and needed something that would empty me fairly quickly and not give me clogs unlike my previous portable one had three years ago. Figured portable pumps have come a long way since then. I also wanted something not as circular so it wasn’t as bulky in my pumping bra as I have to move around a lot for my profession. Most reviews here raved on how my loved their Eufy, even on Reddit so I bit the bullet and bought this. I was in between these, the Elvies and the Momcozys. I even bought Momcozys but returned it unopened since I was convinced these would work better because of the warming feature and the ability to buy more supplies to save even a few minutes during work so I was quicker with pumping. The pumps came earlier than expected so I was excited to have them before I started working so I can to play with the settings and see what mode would work better for me. On my spectra and baby Buddha I get 8-10oz in the morning when I pump exclusively. Or if I feed baby first and then pump I still get 4-5oz left. There are three modes so far I’ve done the max output and the gentle mode. These were the modes recommended by reviewers. When they didn’t work, I tried the others. The output was the same if not worse. I usually get the most on mornings so I pumped each morning to see if there’s any improvement with the tweaks I’ve used. I make sure everything is in place and nipples are centered and I have a tight fit in my bra. First time I pumped I did 20min max output - I got in total 1.5oz Second time I pumped with flange inserts 20min gentle mode - I got a little less than 2oz Third time I pumped with flange inserts and 30 minutes gentle mode - I thought I was doing ok during it (you can’t see milk output unless you pause and fully take it out) - once again I got 1.5 oz It was so upsetting the third time that I put the spectra on right after since I still felt full (despite the recommendation of 30min pumping otherwise you risk nipple/tissue damage), and in 10minutes it gave me 4oz. And each time despite all the borders of container is sealed, it still somehow managed to leak milk out when pouring it into my storage container. For the amount of money this pump can be especially with paying out of pocket for this, it is not worth it. All it has it that it’s pretty and has looks. These are unusable at my work. It would risk me getting a lower milk supply, clogs, and/or mastitis. Now I have to figure out how I’m going to buy another portable again for work, it’s disappointing. By recommendation from users on facebook and Reddit bought the legendary flange inserts. I’ll update this if it improves. But for now stay away from them unless you want to buy something that just sits there useless.

I have been an exclusive pumper since my milk came in. I was using my spectra pump full time for about the first 2 months and WISH I would’ve just used this pump from the beginning knowing what I know now The reason I chose the Eufy pump is because I have been using Eufy security cameras long before I ever had a baby. Then we got the eufy baby camera, then the bay sock monitor. When I started looking for a hands free pump on Amazon I was so excited to see that eufy made a breast pump!!!!! It didn’t have that many reviews like the other big name pumps but I didn’t want to deal with more apps on my phone so i took the risk in hoping I would’ve like Eufys breast pump The first few pump sessions you’ll have to mess around with the settings in the app to see what works for you. The first time I put the pump together I thought it was a little tricky. However, after you assemble the pump about 3 times, it’s now second nature and super easy. I don’t even have to think when taking it apart or putting it back together. Ive never experienced any leaks or incorrect suction etc etc the pump has worked every single time I was a full time spectra girlie. However, I kept experiencing clogs in my right breast EVERY WEEK since my pumping journey began. I hated using the Eufy and only used it if I absolutely had to because everything online says that mobile pumps aren’t as good as plug in pumps. So for the first 2ish months of my pumping journey I had only used the eufy maybe 2-3 times However, I had been battling a clog and engorgement in my right breast for about 3-4 days that would NOT let up at all. We were running around and I had to use the Eufy because I wasn’t home. I have no idea how but the eufy relieved the clog and the engorgement that was happening. Since that day, I have used the eufy FULL TIME as my primary pump which has been for almost 2 months now. So I have used the eufy pump for almost 2 months now EXCLUSIVELY and have not experienced ANY clog or engorgement. And at the time I started using the eufy full time I was pumping 6-7 times a day! AND I get the exact same output with the Eufy that I did with the spectra. So this whole idea of “the wall pumps are better” talk is nonsense to me. I haven’t used the spectra pump in almost 2 months and hope I never have to use it again. I have the exact same output with the eufy. I think for future babies I’m going to go straight to using the eufy full time as well. As a first time mom, using a wall pump is probably more beginner friendly because you do have to learn how to line your nip up ina flange. Doing that in a hands free pump is a little tricky at first because you can’t see anything. Just something to keep in mind if you are a FTM. I also clean this pump exclusively in my bottle washer. I can’t fully attest to the battery life because I charge this thing after every use. I do know that if you use the heat I think you’ll only get about 2 pump sessions without charging it Why I’m giving 4 stars: My dislikes about the eufy pump is that the collection cups only hold about 6oz before it starts spilling out of the top. You also can’t see how full the cups are until it literally starts spilling over. Hopefully they’ll do a redesign someday where the sides where the motor attached are visible so you can actually see the milk line. I also think the app is just okay. My main gripe is that the motors have to be on in order to even view the pump settings and to access the milk output log. The very first time I pumped I LOVED that eufy had their own pumping log to input how much you pumped. But then I quickly realized once you turn the pumps off this info isn’t accessible or viewable or if you forgot to log it and want to add it you can’t get into the log because the pumps are off which is stupid in my opinion. Because of that, I use a separate app to log how much milk I made. I also HATE the flange inserts that eufy gives you. I now use the Nursi Luna inserts with my pump. I also dislike that there’s no timer on the physical motor. Not a huge deal but it would be nice if it was there. I also didn’t know that you could physically start the pump by clicking the power button twice. And that you could pause the pump by hitting the power button once you’re pumping. I thought you could only start, stop, and pause the pump in the app and was using it like this for an entire month until I accidentally figured it out one day. In all, I love my eufy pump. I haven’t had any clog or engorgement issue with it. I use the pump full time now. Because I use the eufy now, it makes my pumping journey not as awful lol. I was about to lose my mind using the spectra am but changing to eufy saved my pumping journey!!!!!!!

I absolutely LOVE this breast pump. I basically use it as my primary pump. The flange inserts are also my favorite out of all of the brands I’ve tried. I prefer these over my spectra, and I get about the same output or more with these compared to the spectra. I tried the motif aura glow wearables, and that motor was not nearly as good as my Eufy’s. I absolutely love the charging case too. Would charge at night, and the pumps would last though all of my sessions at work without me having to worry about less power or them dying. The price is high for these, but was ABSOLUTELY worth it for me. I’ve been breastfeeding for 10 months now and it couldn’t have been accomplished without having such an amazing product to have on the go. The one thing I wish these came with is a wet/dry carrying case, but that is easily purchased for cheaper elsewhere. Also, replacement parts off of Eufy’s website are a bit pricey too.

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?

Day 1: I really am enjoying them. I took my time to review the manual and washed them and re assembled everything. Very straightforward. I got another known brand set and returned it due to a strong manufacturing odor. These had it sooo slightly you had to shove your nose right in and focus to smell it. And after the wash it was completely gone, not like the other one. (Quality product!!) They are very comfortable to wear, lightweight. The light feature isn’t something I’ve needed yet. The massage and heat are amazing. My breasts we’re starting to get hard lumps from the little guy not being able to latch (I am well equipped) and after the first use I got relief from that! I find them to be quiet, I was so tired of my spectra milking me lol I felt like a real cow lol. I still don’t know how far back/forward I can lean in them, till it’s a problem. The app is straightforward. I wish it auto tracked how much you pumped. I guess the S1 has that feature. But from what I read from people who upgraded is that these are more comfortable. So I’ll take comfort over a small thing like tracking output automatically But I’m trying to be fully breastmilk (breastfeeding and pumping) and it was worth the investment to be comfortable and mobile. I feel my sanity has improved. Output is the same so far. I am hoping to get more once my breasts adjust. I will post an update if I remember. Update >1week later: still my favorite. The light feature is nice at night. And I’ll turn it on to see my output. Still very comfortable and quiet. My friend gave me 5 pumps to try and I thought I’d switch from the eufy. None of them compared. One had a strong suction but OMG it was loud. To be honest this is really a great investment for me. The one thing that is kind of a bummer is that the case is constantly charging the pumps so the battery drains. But that’s about it. And I only charged the case once and it’s been over a week. So not too bad. Assembly is still easy, I don’t find it to have any hard to clean areas. The flanges go in so smooth too. 5 out of 5 for sure

Produit de remplacement pour mes pompes préférées. Vaut vraiment le prix.

Perfect to use with eufy pump.

Passen, sind dicht, perfekt. Genau so hab ich sie gebraucht.

Great extra charging cord

I use them while pumping and it seems to create more suction power. I think they should come with every set of pumps though. Disappointed I had to buy separately.
