eufy Breast Pump S1, Wearable Electric Breast Pump with Heating Technology | Hands-Free Electrical Pump, App-Controlled Smart Rhythm, Hospital-Grade Suction, Portable Design, Leak-Proof and Ultra-Quiet

My partner has been using this regularly since the birth of our son, and it has made a noticeable difference to her pumping experience compared to more traditional pumps. The wearable design gives her much more freedom to move around rather than being tied to a chair, which is particularly valuable when there is a newborn and an older child to look after. The heating function is a feature we were initially sceptical about, but it has turned out to be genuinely useful. It makes pumping more comfortable and seems to help with milk flow, especially during longer sessions. The suction is strong without feeling overly aggressive, and the different settings available through the app make it easy to find a comfortable rhythm. Battery life has been excellent, and the charging case is particularly convenient. It means the pump is always ready to use without having to constantly think about charging cables. Another pleasant surprise has been how quiet it is. Pumping can be done discreetly without drawing much attention, whether at home or when out and about. Cleaning is straightforward once you get familiar with the components, and the overall build quality feels premium and well thought out. After several weeks of regular use, it has performed consistently and has become an essential part of our daily routine. Whilst it is certainly an investment, the convenience, comfort and flexibility it provides have made it well worth the cost for our family.

So first time trying eufy breast pumps and I’ve just finished using it and I am very impressed. There are a lot of parts to the pumps which can be quite fiddly however they are easy to assemble. And I love the fact it has all the information on the app and in the book that arrives with the pumps. The heating feature is a new one to me and I honestly quite liked it! I feel it will be perfect in the winter. The massage feature again is a bit strange at first as it is a vibration but doesn’t feel terrible! The output, well I had just put my little boy to bed after a full days feeding & playing and I set the timer on the app for a 15 minute pump. In the 20 minutes I got just over 2 oz which may not seem like a lot but my boy likes long feeds so I was impressed. I also like that I can see that it is pumping milk rather than on other pumps where you are pretty much guessing. The app is straight forward to use once the pumps are connected. As mentioned you can set the pumps for how long you desire to pump for and control the heating/ massage feature and the pump level. Charging these are magnetic connectors so there is no messing about with making sure the plugs are in the right way. However they can easily come out if they are knocked. There is a digital display for the charging % as well. Overall I must say I’m really happy with these pumps and they are quiet compared to the other model I used. Worth the money imo. Please note this is me comparing a competitor pump that I did not like due to pinching!

Review dated June 2026: I am very impressed by this pump! I have a spectra s1, but I needed something when I am out. The Eufy s2 pro is as good in terms of suction and provides a good output. I know it’s on a pricier side but I feel it’s worth it. Updated review August 2026: As I was using the Eufy s2 as my primary pump I noticed that my case was not working properly. I got in contact with Amazon to report an issue a week prior to the cut of time for a return. The representative has offered me a refund and a confirmation email was sent to my email address. I was advised just to get a new pump from Amazon as the one I have is not in the correct working order. Later I received an email ‘violating Amazon returns policy’. I tried to get in contact with the team several times without any resolution and I was just pushed to the ‘specialist team’ that would never respond nor offer me an explanation. I now got in contact with the Amazon customer service team again that just directed me to the Eufy team and then disconnected. I am very disappointed in the Amazon team that I have been using for years…

I'm a STM who exclusively pumped with my first child so I knew I wanted something effective and that I could easily move around with. I love this pump. At first it can feel a bit fiddly to assemble, but you soon get the knack of it. It is really effective with strong suction. I love the heating mode and that it automatically shuts off after 30 mins in case you fall asleep with it on. They hold a charge well and I like the charging/storage case. Easily sterilised in a cold water steriliser. When emptying the milk pour with the silicone part that sits on the breast facing up or you lose a little milk from the nipple hole. Would definitely recommend.

I purchased this pump after being enticed by the heating features, app control and aesthetic. I used approximately 6 weeks post partum and I instantly fell in love with it! The heating feature made it so much more nicer to pump especially when feeling engorged and sore. The ease and comfortability of the pump was incredible and was my go to pump for most of my pumping journey alongside the spectra S1. However, after a couple months use the charging case stopped working and was quite frustrating as this was the main source of charging especially as I was abroad when this happened! With the Eufy S2 now out, I am even more tempered to purchase this upgraded version with all its features but not sure if I can justify the money! Overall would recommend!

Absolutely amazing. I initially dealt with some setting issues like "heating/warming" but after learning the settings on the app, it was resolved successfully. The reason i had purchased this pump was my supply, which had dropped significantly and as i am exclusively pumping, it was really disappointing to start feeding my baby with the ready to use formula !!! Right after the first use, i was able to pump a pretty good amount of milk. Its just the second day of use and i am starting to store the milk which explains well how efficiently it increases the supply and empties the breasts. The massaging and the warming features are a total game changer as you feel less of a pumping and more of a massaging thing going on for the period its on. The light 💡 feature is absolutely amazing as it helps to check the amount during and after the pump at night or even during the day...and you can turn it off as per your convenience. The absolute shocking thing to me is the Eufy app. It controls the pump like a real magic unlike the other big brands like m*mcozy which were just boring to use and had no other features than a very few and basics. Once i was able to use the app correctly, for example, the power of the massage mode, heating, timing, alarm, pump data, baby log and especially the different levels and angles of massage....simply wow and salute to the manufacturers. Thanks for making the pumping absolute fun and game changing.

I like this pump and use it frequently… however the heating elements went after about 3 weeks which for the price is a bit disappointing… it is comfortable and having the different modes and suction is great and the heating was nice until it stopped working… I would say get this if you don’t mind paying high prices to replace parts frequently

I love the heat feature and I definitely think it helped me! After watching loads and loads of breast pump reviews, I ended up buying these and I'm 100% happy with them. There are so many product reviews out there mostly with a discount code so I did not trust them. I'm glad I took my time and bought Eufy because I really believe it helped me with increase my milk supply. My baby was mixed feed because I did not believe I was supplying enough. I used this pump to help me supply more. Now I only give her one bottle a day just for peace of my mind but she doesn't finish her bottle so I think I've been supplying her just enough! My baby is 7MO and I used this pump mostly when she was 3-4 MO. I do not need to use it anymore ♥️

I bought the Eufy S1 Pro from Amazon for €30 less than the price on other websites, and my first impression is absolutely amazing. It arrived in an incredibly beautiful and well-designed box, and the packaging was extremely protective. For a breast pump, the overall quality feels extremely premium. I haven’t used it yet, so I can’t comment on its pumping performance just yet, but even the spare parts, color, texture, and every little detail feel so thoughtfully designed and made with great quality. I honestly love it. This is what design and marketing should look like. It almost feels like opening an iPhone. Even the cable and cleaning brush are the same color as the pump and the packaging, they’ve thought about everything. My first impression of this breast pump is fantastic. I’ll update my review once I use it and can evaluate its actual performance and efficiency, but so far, I’m seriously impressed!

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.

Werkt geweldig, ongeveer dezelfde output als m’n Medela freestyle flex.

I transitioned from Medela Symphony to this, took three days to get used to the different rhythm but once you were there, it really made everything so much easier. Now I can pump and eat or do something else at the same time. Way better than being locked at one place with tubes attached to you. I also really like the heating feature! Nice plus to the device. So yes, best decision ever.

I really thought I couldn’t get a wearable pump that would work with my elastic tissue but I’ve gotten the same if not more output with this pump as with my spectra. It feels expensive, all of the parts are easy to put together and clean and I like the ability to use the app or the pump buttons. The heating feature is amazing and that it comes with silicone flange inserts for a correct fit. SO pleased with this purchase.
