Q&A
Have a question? Ask an expert.
Start typing and see existing answers.
Can these go into a bottle washer to clean?
Best Answer: All washable components of the S1 (like collection cups, flanges, valves, and diaphragms) are dishwasher-safe, but must be placed only on the top rack. Always keep the pump hub dry and out of any washer.
Can you turn the pumps on and off from your phone? ?
Best Answer: Yes, you can turn the Eufy S1 Wearable Breast Pump on and off from your phone using the Eufy Baby app. The app allows you to remotely control the pump, including starting and stopping sessions, adjusting suction levels, switching between stimulation and expression modes, and managing heating settings.
Does this come with a case? Or just dust covers? Is it a hard case?
Best Answer: The eufy S1 Wearable Breast Pump does not come with a hard carrying case. It includes soft dust covers made from food-grade plastic to keep the flanges clean and protected when not in use.
How many parts are there to clean?
Best Answer: The Wearable Breast Pump S1 has 4 parts that need to be washed.
Does this come with the charging case as well?
Best Answer: No, the charging case comes with the S1 Pro.
How does this charge? ?
Best Answer: To charge, align the magnetic charging pins on the pump hub with the charging ports inside the charging case, ensuring a click is heard to indicate proper connection. The charging light will then indicate the charging progress. You can also charge the pump directly using a magnetic charging cable plugged into the pump hub.
How many ounces does this hold ?
Best Answer: The capacity is 5oz. or 150ml.
Does this have back flow technology to prevent spillage when it’s full?
Best Answer: Yes, it's a closed, anti-backflow design.
What is the suction strength?
Best Answer: This pump helps to achieve maximum milk output with up to 300 mmHg of safe, hospital-grade suction. You can also customize the suction strength and cycle speed to suit your needs.
Can you use this pump overnight as you sleep? And if so, how would that work?
Best Answer: Here is Eufy's response: Although using a wearable breast pump while sleeping may seem efficient, it's generally not advised. The risk of leakage, discomfort, and continuous suction can disrupt your sleep and potentially cause various issues. These include physical trauma to the breasts and nipples, or even complications like mastitis due to excessive or improper use.

Meh.
I was so excited to to get these pumps, after using them I realized that they were completely destroying my nipples. Even the gentle setting was too rough. It made my nipples so raw that I couldn’t even stand facing the shower head and letting water hit them because it hurt so bad. I think that there are better pumps for the amount of money you’ll spend, these simply didn’t work for me.

Motor quit working.
Motor went out after 3 weeks of using it. When I put the pump on and pumped for a 15 min session I would get nothing out. My breast was engorged so it was definitely full. I restarted the pump and would get 3-5 ounces out. This is happening more frequently and I have to restart the pump 2-3 times before it works. Contacted eufy via email because there is no phone number and they have to investigate the situation before sending me a replacement motor. I have noticed a dip in my supply on that side due to lack of being able to pump. Do not recommend this pump for that reason.

Gamechanger
This is such a gamechanger! I get better output than Spectra and it’s so much more convenient to wear and clean. Highly recco!

Even my lactation consultant asked for the link!
This pump is a lifesaver! So comfortable and way less overstimulating than the hospital recommended one that locks me in place with a plug to the wall!

It worked exceptionally well. Enough to keep twin bed for 4 months now
This was for my granddaughter who was expecting twins when I purchased it for her. The boys are now almost 4 months old and she is still using it. It has been excellent for her to be able to feed both babies using the pump. We would recommend it to anyone!

Great wearable option
I seriously loved this pump! My wall pump was a Spectra S1, and I got equal if not better output with my Eufy. Worked great when my baby was in his fussy phase and did not want to be put down. I loved the heating function especially. I would turn it on and let it warm up before putting it on so it would be more comfortable, and it helped with my output and keeping me relaxed. It was pretty powerful and had a couple of options for rhythm which was nice. I will say, the app is slightly delayed…

Love this pump!
No more being tired to a wall! I used to cry with my old pump, because I could never get a full session in with a newborn. With these I was able to tend to my crying baby, and pump at the same time. You can do pretty much everything with these in. They also sell separate pieces to plug the pour spout at the top so that it doesn’t leak if you bend down to pick something up. The heat function is great and definitely helped with output. Works great for my “elastic n*pples”

I really loved mine. Ended gifting it away to a friend after my BF journey ended. Trial and errors to get going. Facebook has a community support group for these. I liked the app for this as well.

Best wearables on the market
This pump was a game changer I was able to pump and still do my job at work treating patients. Also got such a good out put of milk with these some times more than my spectra!
