eufy Heated Wearable Breast Pump S1 Pro, Charging Case, Hands-Free | HeatFlow, 5-Day Battery, App DIY Rhythm, Powerful 300mmHg, 30% More Output, 46dB Quiet, BPA-Free

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 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.

I bought this product in March ‘26 and have been using it for the past 4 months at least. I bought it to pump milk for my second born, who is exclusively breastfed. I had initially bought a few handsfree pumps (for my first born), but they either weren’t comfortable or didn’t sit well, so I had to return them. With Eufy, I was skeptical, but I was going to return to work and didn’t want to carry my Spectra and all its parts, let alone wash it all. The Eufy wearable pump gave me milk output almost similar to my Spectra, and it was comfortable, with minimal and easy-to-wash parts. It has been so easy to carry, charge, and pump. This is easily the best investment I’ve made. The only thing that could probably be improved is pouring milk from the container into the bottles — there’s a little spill from the spout (the U design), which I believe is due to the design. Despite that, I’m giving it a 5 (4.5 isn’t available) because I’ve been able to find a workaround, but that spill point could be improved, as breastmilk is precious and any amount spilled is just heartbreaking.

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.

I love that there are not a lot of tiny parts to put together or clean. Added plus are the included flange inserts. While I personally think I get about an ounce more output per side with my spectra, these are wonderful for taking to work, pumping on the go, or pumping while still having use of your hands. I’m already big chested so I wouldn’t necessarily wear out and about because I’d look ridiculous, but they are quiet enough that a person probably could. The app is great because it has different pump cycle settings, output tracking ability, and other functions. App is not necessary tho, everything can be controlled right on the wearable, pretty cool. Each one holds about 6oz max before it’ll spill on you, so if you are an oversupplied like me, you do need to keep watch! Great purchase tho, would recommend!

Excellent pump! I had a donated M6 from a family friend but I’m not sure if the motors were bad or if they’re just weak overall, but the eufy goes above and beyond in comparison. It feels so much more luxurious, it heats, has the app, and the case is the cherry on top. I was using the motif Luna and the level 3 on the motif is about the same as the 3 or 4 on the eufy. The app is completely free with no subscription and the pre-set pumping modes/patterns are good and customizable. It’s also easy to clean and reassemble as well as unattaching the motor is easier than the M6 once you learn the “trick”. I would highly recommend!

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.

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.

Perfect to use with eufy pump.

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

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

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.
