Description
Breast Pump S1 Pro Breast Pump S2 Pro Breast Pump S1 Breast Pump E20 Bottle Washer S1 Pro 4K Baby Monitor E21 S1 Pro/S1/E20 Accessories Q: Why can't I feel much suction? A: Breast pump suction is limited to 40 kPa by international standards to protect breasts and capillaries, so the suction may feel soft. If you're using a new pump, check it's working properly and you've set the right mode for optimal performance. Q: How to ensure proper heating for S1&S1Pro? A: Make sure the heating pins are fully extended, the pump hub is securely attached, and there's no gap between the hub and diaphragm. Press the heating button. If you see a solid orange light, the heating is on. If it flashes orange, repeat the steps. Q: What should I know about charging S1&S1Pro? A: Wipe the pump hub and keep it dry. Use a magnetic charging cable with a 5V/2A or higher rating adapter. S1Pro can also be charged via the charging case. When pump and case are fully charged, use without heating for 20 mins/session, 3 times/day, the case can last 5 days. Q: Can I use a microwave to sterilize eufy breast pumps? A: No, it can damage the components and cause malfunctions. Initial Use: Steam washable parts or boil with constant stirring for up to 5 minutes. Daily Cleaning: Rinse washable parts with warm, soapy water and air dry. Sterilize as needed. Q: Where can I get help on usage? A: You can join our eufy Baby&Mom Care Official Group on Facebook to get peer support, along with tips and tricks from lactation consultants.

Size: Massage Heated S2 Pro
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

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!

I am a nurse on a busy floor, these breast pumps have been a life saver for me. Easy to use, the heating feature really does help with my letdown, easy to clean, and the charging case is a game changer. I can use the pumps multiple times a day without having to recharge the pumps or the case itself. The battery life on the case lasts for a pretty long time. The suction was also strong, which was impressive to me. For wearable pumps, these are a pretty good choice. Way better than momcozys in my opinion. If you’re contemplating whether or not to buy these, yes they are expensive but I would say it’s money well spent. 10/10 would recommend.

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 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.

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 liked this pump a lot at first—it’s super convenient being hands-free, and the heated feature felt really nice in the beginning. It worked well for me for the first few weeks and made pumping feel a little more comfortable and efficient. That said, I ended up having some issues with clogged lymphatic fluid, which then led to clogged ducts. After talking with my lactation consultant, I was advised to stop using heat and switch to ice instead, and that made a big difference for me. I also noticed the diaphragm tends to leak—especially if you’re holding it upside down. You have to keep a hand over it so it doesn’t fall out and spill, which isn’t ideal when you’re already multitasking. Overall, I do think it’s a well-designed pump and has some great features, but it just wasn’t the best long-term daily option for my body personally.

✨ MY EUFY S2 PRO ✨ I was already a huge fan of the eufy S1 Pro, so when the S2 Pro was released, I knew I had to get my hands on them and it definitely lived up to the hype. First of all... the night light is such a thoughtful touch for those middle of the night pumping sessions. It's also one of the quietest wearable pumps I've used, making it easy to pump without disturbing everyone around me. The suction is strong, yet incredibly comfortable. I never experience any pinching, and the customizable settings let you truly make each session your own. Being able to adjust the heat, massage, suction & rhythm separately is such a game changer. Can we also appreciate the little details? 🤍 The diaphragm has a built in tab, making it so much easier to remove & the built in pour spout helps transfer milk into a bottle or storage bag without the usual mess. It's clear this pump was designed with real moms in mind. The heat & massage feature is something I can actually feel & it makes pumping feel so much more comfortable and relaxing! Another feature I especially love is the automatic shutoff. If you're a mama with an oversupply or you get caught up caring for your little one, you can have peace of mind knowing the pump won't just keep running and overfill. And can we talk about the color? 🌸 The soft rose pink is absolutely gorgeous. It's sleek, premium & honestly one of the prettiest wearable pumps I've seen. This is one of those products that combines thoughtful design, comfort & functionality so well and it shows in every detail. Obsessed.
