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

I’ve had the Eufy S2 Pro for a little over a month now, and I absolutely LOVE it. As far as milk output goes, it has honestly been comparable to my stationary Motif Luna—which says a lot because the Luna has been my reliable workhorse. The massage and heating features are probably my favorite part. They really help with my letdowns, and for me, better letdowns = more milk expressed during a session. The best way I can describe it? It’s like giving your breasts a gentle, warm deep-tissue massage while you pump. 😂 And YES, it makes a difference! Since returning to work, this pump has been a godsend. I work in sales, so disappearing into the lactation room for long stretches several times a day just isn’t ideal. Before getting the S2 Pro, my previous wearable pump (Willow Go) stopped working properly, so I had to bring my Motif Luna to work. A pumping session could easily turn into an hour—about 30 minutes pumping and another 30 minutes cleaning, sanitizing, and drying everything so I could do it all over again three hours later. And as a first-time mom, nobody told me I was going to need pump parts like I was stocking a small warehouse. 😂 I learned QUICKLY. Because I pump every three hours—usually 2–3 times while I’m at work—I now keep two sets of flanges, cups, and the other parts I need. I can pump, pack that set away, grab a clean set for the next session, and keep my day moving. The pumping journey really is a JOURNEY. So many things can affect your output. In the beginning, I was getting around 2 oz total during some pumping sessions. Now, I’m regularly getting about 3–4 oz PER BREAST during a session. Obviously, milk supply can change for many reasons, but the Eufy S2 Pro has absolutely become an important part of what’s working for me. One tip I’ve learned: your bra matters! I get better results when the pump is held snugly against my breast. Not painfully tight, but secure enough that the massage feature can really do its thing. That’s when that “deep-tissue massage” feeling comes into play. 😂 I know some people will look at the price and think, “That is A LOT for a breast pump.” I get it. But for me, the convenience has been worth it. I can be hands-free, mobile, continue working, AND have a pump that massages and heats while giving me output comparable to my stationary pump. For a working, pumping mom, that extra freedom is worth a lot. The Eufy S2 Pro didn’t make pumping effortless—because let’s be real, pumping is basically a part-time job nobody put on the job description—but it has made my pumping journey MUCH easier. ❤️

I have been using my eufy s1 pro for 3 months now and I LOVE it. I saw a twin mom on Forbes who tested a ton of breast pumps and this one was her winner. Her review convinced me and I’m so glad it did. I use this 3x a week at school and it’s so convenient. I refrigerate my parts between pumping sessions and that has worked well for me because it isn’t realistic to wash or sanitize pump parts at school. The heating feature solves the issue of freezing cold pump parts during a pump session. I got the charging case too and that is a huge win. Fits great in my backpack and keeps the motors ready to go when I need to pump. If you’re on the fence over the price, let me tell you it is well worth it. It’s a comfortable pump (though I had to buy separate flange inserts bc I’m a 13mm flange 🫪) and fits great in my bra. I love love love this pump and it makes it so I can do other things like homework while pumping between college classes.

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.

One of my favorite pumps overall. I have 3 wearables that include this one and two wired ones overall this and my NCVI collection cup one are my favorites. I thoroughly enjoy the heating element of the pump, it makes a huge difference to my output. I also really enjoy the fact the charger has both heads in one wire, it makes charging the motors so much easier compared to all my other's. I love the bag and the covers for the pump itself. It makes travel so much easier, this coming from a full-time working momma. I enjoy having an app where you can figure out how long it’s been pumping, can even change settings/important other people’s settings, adjust heating element, and track your output. Cleaning is super easy and it comes with tools to maintain your pump parts. Overall it is an amazing pump and I highly suggest it. Now the only negative thing which isn’t bad because of the app, is just the fact you cannot see how long you’re pumping. Of course, if you’re on the app it tracks your progress, but I do sometimes hate that I have to be on the app to realize how long I’ve been pumping.

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.

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?

Bottom Line Up Front: I have tried a handful of pumps out and this is by far my favorite and has become my go to! The things that I do not like about this pump: The measurement lines are only on one side of the collection cup, and they are incredibly inaccurate. in the picture, you can see the volume in the collection cups to measure just over 8.5 ounces, however, when taken out and measured in a Dr Brown's bottle, it was right at 8 ounces. This isn't a huge problem, but is frustrating if you're a person who likes to track these things. The app has quite a bit of a learning curve. Again, not a dealbreaker, but there doesn't appear to be away to just control the pump on the app (aka turn level up/down, switch between stim and expression, like what you would see on controls of a more traditional pump). Instead, you have to select a pattern within the app, or create one. If you're someone who doesn't want to be messing with that, I wouldn't recommend this pump. It took me a couple of days and a little bit of trial and error, but I was able to figure out the app just fine. HOWEVER, this ended up being one of the things that I did love about it. Once you create a pattern of what exactly works for you and how long you want it on. Then you can put it on and just forget about it. The pour spout opening will overflow if you are expressing more than 5 oz. There is no plug for the opening like you see on the momcozy pumps. So if you express more than 5 oz the pump will keep going, there is no auto shut off, and inevitably start spilling out the top. Here are the things I did like! The warming is SUCH a game changer. My middle day sessions are usually much lower, especially if I’m not using my wall pump. However with the Eufy, I’m getting almost exactly as much as I do with my Spectra. The charging cable is a single cable with two charging ports coming out of it. This is such a simple design choice, but omg it’s so nice to have to detangle a bunch of cables! It’s pretty quiet! In the past I would’ve never worn my wearables in public, but I actually use these in public places without feeling like it’s crazy noticeable. Lastly and most importantly the suction is soooooo gentle. The entire flange is so soft.

I originally had an issue with my shipment and had to reorder, but once I finally received these, they've become one of my favorite wearable pumps (until the S2 Pro). The biggest pro is the output. I get excellent milk production with these, and the heating feature is amazing - it really helps with comfort and milk flow. They've been reliable, and I use them regularly. I wouldn't say my supply has severely increased, but they definitely do a great job at maintaining my supply and emptying. There are a few downsides. I find them a little pinchy, even when using flange inserts. They're also more time consuming to clean because of all the small crevices. The included cleaning brush was a nice idea, but it scratched my milk collection cups, and I accidentally tore one of the duckbill valves while cleaning. Replacement parts are also on the expensive side, so that's something to keep in mind. They're not quite as discreet as I had hoped. I personally wouldn't wear them out in public unless I had a sweatshirt or hoodie on, and coworkers on conference calls have mentioned they can hear the motors, so I still use the mother's room at work. Overall, despite the drawbacks, the heating function and strong output make these a wearable pump I'd recommend. Just be prepared for a little extra maintenance and higher replacement part costs.

Work Very well

Alles super, passt perfekt, da originale Ersatzteile

I purchased these as my eufy was leaking when it got full. These absolutely avoid spills when moving around. It's a shame they don't come with the pump as standard.

Works great but they are super small, it’s easy to lose them

Works perfectly and it is very useful!
