Why you’ll love Mother’s Nature W1
WARMING
Soothing Warmth, Naturally Effective
Designed to mimic the natural warmth of your baby, the W1 warming shield encourages oxytocin release, helping milk ducts relax and open for a smoother, more productive pump. The spa-like warmth rises and falls in a calming cycle, easing tension, softening breast tissue, and supporting a faster, more comfortable let-down. The result is a pumping experience that feels nurturing, efficient, and wonderfully relaxing.
BIOMIMICKING
Expertly Designed to Feel More Natural
By mirroring the natural cues your baby provides - warmth, rhythm, and gentle stimulation- the W1 works in harmony with your body’s biological response to nursing to help encourage maximized milk flow in a way that feels intuitive, comfortable, and closer to nature than ever before.
12 SUCTION LEVELS
Because Every Body Is Different
Every mom’s body, and every pumping session, is different. That’s why Mother’s Nature™ W1 offers 12 adjustable suction levels, giving you precise control to find what feels most comfortable and effective for you. Easily move from gentle stimulation to stronger expression as your body responds, so you can pump efficiently without sacrificing comfort.
4 PUMPING MODES
Designed to Work With Your Body
Mother’s Nature™ W1 offers 4 thoughtfully designed pumping modes to support every stage of your session - including the NEW BioBoost™ Mode, a power pumping feature that is designed to work in harmony with your body, using a specialized rhythm inspired by baby’s cluster feeding patterns to help mom’s body produce more milk. From gentle stimulation to efficient expression, each mode gives you the flexibility to pump more comfortably, more naturally, and more effectively.
ACCESSORIES
Everything You Need, Included
Includes a complete set of accessories designed to support comfort, convenience, and confidence from day one. With more sizing options than any other pump, it’s easier to find a fit that truly works for your body. And thoughtful extras make everyday use simpler - like a magnetic charging cable for effortless power-ups or extra duckbill valves with a built-in pull tab for easy removal. It’s a smarter, more supportive setup, ready to use right out of the box.1
- Sizing options here means every size a W1 mom can use at no extra cost, six in all: the 24 mm breast shields and 15, 17, 19, and 21 mm inserts the W1 includes, plus a 13 mm insert through our Perfect Fit Promise™.

At first I didn’t respond too well to this pump but then I used the BioBoost mode and now it’s my primary pump. I usually use one set and alternate between breasts on and off all day so there’s less washing however these are easy to wash. The pull tab on the diaphragm makes washing such a small piece much easier. Sadly the warming feature didn’t do too much for me but I do feel the warmth. It’s nothing intense, it more so knocks the chill off the silicone. The silicone breast shield is soft and feels nice but like any silicone it is a dust magnet. I wish it came with dust covers. The pour spout stopper is absolutely not leak proof. If you bend over too far milk will come out but I do like having it to help keep anything out of the collection cup. The pump is easy to assemble and disassemble and charge. Charging time isn’t fast but it also doesn’t take all day either which is nice. I’m pleased with the battery life. The motors last throughout the day but I don’t think they’d make it through a whole day and night especially if the warming feature is used. I’ve only had the seal come undone and leak milk once and it may have been my fault. I love that Zomee sends so many inserts so you can try different sizes. I also love that they sent charging blocks and not just cords! And there’s two blocks and two cords. I love that there’s so few parts to this pump and they’re all easy to clean. The motor is simple and easy to use but still has customizable options within the settings. No bluetooth!! I love it. No app or anything to complicate things, just turn it on and go. And the nightlight is a nice touch to help me see my output while under my shirt. The collection cups have a little foot to keep them upright when you set them down to help prevent spills. This pump is straight forward and effective without being complicated.
I was on the hunt for an AFFORDABLE wearable that did a great job that had the warming feature that another brand I had heard about had. So I of course searched Tik tok and came across this one and it was so much more affordable! So in my cart it went and it’s hands down the best pump I’ve used in my journey (kid #3). I have great output and it empties me quick! I had heard on a lot of reviews that the warming feature wasn’t as warm as some would like but in my opinion I wouldn’t want it any warmer! I will say I wish that it wasn’t automatic to change settings when you first turn it on. I like that it changes to expression after stimulating but i usually only use those two modes alone and it goes through more than just those. But once you change it it sticks to what you want for that session so overall I’m very happy with my purchase!
As an enougher, I found out this has been a hit or miss with me on giving me the same output from my Spectra. Controls are intuitive, love the silicone material of the flanges, and the heat function is just warm enough to be noticeable. I was slightly misled and disappointed by the memory function or the auto switch mode, this was not explained properly on the manual. Thankfully, the Zomee website bot was helpful. Also, it could have been nice if there is a way to assign or differentiate the motors as left and right since I have different levels for each boob.

W1 FAQs
What makes the Mother’s Nature™ W1 different from other wearable breast pumps?
The W1 is the first warming wearable pump with NatureWarm™ Technology designed to mimic a baby’s natural warmth and nursing rhythm. This gentle warmth helps trigger your body’s natural let-down reflex for faster, more comfortable milk flow - giving you a truly nature-inspired, hospital-grade pumping experience in a compact, hands-free design.
Is the W1 quiet enough to wear discreetly?
Yes, it is. The W1 runs at 46 decibels, about as quiet as a whisper, so you can wear it under clothing at work, out running errands, or around others without drawing attention.
How does the warming feature help with milk flow?
Gentle warmth relaxes breast tissue, boosts circulation, and promotes the release of oxytocin - the hormone that triggers milk release from milk ducts. This makes pumping feel more natural, comfortable, and effective, helping moms express more milk in less time.
What is BioBoost™ Mode?
BioBoost™ Mode is designed to mimic cluster feeding, a natural pattern during baby’s growth spurts. It sends strong signals to your body to boost prolactin levels and help increase milk supply. Use this setting when you want the added stimulation, or skip it — your pump will continue to provide its full pumping benefits either way.
How long does the battery last?
A full charge takes about 90 minutes and provides over 120 minutes of pumping time, enough for multiple sessions throughout the day.
What makes the Mother’s Nature™ W1 different from the Zomee Fit wearable breast pump?
Compared to the Zomee Fit, the Mother’s Nature™ W1 offers NatureWarm™ gentle rotating warmth, while the Fit is non-warming. The W1 provides suction up to 300 mmHg versus up to 280 mmHg on the Fit, and includes Stimulation, Expression, 2-Phase, and BioBoost™ modes, compared to Stimulation, Expression, 2-Phase, and Nipple Correction on the Fit. Both have a 6 oz. container capacity and the same extra parts (duckbill valves, diaphragms, bra strap adjusters, and container brush). Charging time is 1.5 hours for the W1, compared to 2 hours, or a 30-minute quick charge, for the Fit.
How does NatureWarm™ work?
Many pumpers use a warm compress before pumping to promote comfort and support milk flow. Gentle warmth can help relax the breast and milk ducts, which may support faster milk release and improved milk flow. When activated, the pump continuously cycles between 95°–105°F throughout the entire pumping session, providing soothing warmth right when you need it. You can use the warming feature when you want the added benefits of gentle warmth, or skip it — the pump will still provide its full pumping functionality without it.
