The Lacevo S70: The Smart, Stylish Wearable That Pumps Like a Pro
By Jessica, IBCLC at Genuine Lactation
There’s a new wearable pump on the market, and it’s not just another pastel plastic knockoff. The Lacevo S70 is a sleek, smart, app-controlled wearable that’s powerful, thoughtfully designed, and actually delivers. After testing it extensively, I can confidently say: this pump is absolutely worth your attention—and potentially a spot in your rotation.
I’ve been tracking the Lacevo for a while, especially since it's been available in Australia (where I support many clients). Now that it’s landed in the U.S., I finally got my hands on it, gave it a thorough trial, and wow—there’s a lot to love.
🍼 What Makes the Lacevo S70 Special?
The Lacevo S70 is priced as a luxury wearable pump (currently ~$360 USD), but unlike many others in that category, it justifies that price tag. Here’s what makes it stand out:
App-controlled with 4 customizable modes (and 12 levels in each)
Powerful suction: up to 280 mmHg
Smart but optional Bluetooth: run manually to save battery
6 oz capacity with overfill sensor (sensor can be disabled in the app)
Silicone flange with wide-angle fit: grippy, minimal compression
Includes 13, 15, 17, 19 mm inserts with a silicone roller for flange sizing
Elegant, well-designed carry case with upright storage and wet bag clip
Fits more body types than many wearables, thanks to the flange curve
⚙️ Let’s Talk Modes: A Truly Custom Experience
The Lacevo S70 doesn’t just offer a basic “stimulation vs expression” toggle. Instead, it gives you four distinct, thoughtfully-programmed modes—each designed to mimic different pumping rhythms and sensations. These modes are represented by unique icons on the pump itself:

💪 Fit, Feel & Functionality
The flange design is one of the most universally accommodating I’ve seen. It’s got the wide curve of the OG Medela cups (the ones everyone loved), but with a slightly grippy, padded silicone rim. That means it stays in place comfortably, doesn’t over-compress breast tissue, and works well for both small and large breasts.
When paired with the right bra and correct flange sizing, this pump delivers some of the gentlest, most effective suction I’ve experienced in a wearable.
👜 Accessories That Actually Solve Problems
The included carry case deserves its own shout-out. It’s not a charging case, but it’s everything you wish other cases were:
Keeps motors upright and protected from milk or crumbs (yes, really)
Has a wet bag clip that stays separate from the clean pump parts
Provides upright storage for pulling pumps out mid-car ride without spilling
Holds your inserts, cords, parts, and extras with room to spare
This was clearly designed by a parent who has pumped in a car, in a meeting, and in chaos—and wanted to make life easier.
🔊 Real Talk: What to Expect
Noise Level: This pump is not discreetly quiet. It’s about as loud as the BabyBuddha or Momcozy Air 1, with a distinct vibration sound. Not ideal for silent environments, but fine in most homes, offices, or on-the-go settings.
Insert Fit: The included inserts are high quality but snug. If you're using oils or have damp hands, they can be hard to insert. Luckily, it's compatible with Willow and Maymom short inserts for easier handling.
Bluetooth Quirks: You may need to reconnect the Bluetooth if you’ve used it manually. But on the plus side, manual mode preserves battery, unlike Elvie or Willow Go, which drain quickly due to constant connectivity.
Cost of Replacement Parts: Still being determined. As soon as we know more, we’ll update the Wearable Pump Paperweight Calculator so you can compare long-term value.
👩💻 Designed by a Pumping Mom, for Pumping Moms
During my call with the Lacevo CEO, it was immediately obvious: this pump wasn’t designed by a marketing team—it was designed by a mom who pumped and paid attention. From flange sizing guidance that doesn’t overestimate (no more “add 4mm” nonsense) to insert kits that include hard-to-find sizes and smart case design, this is pumping equipment made with real-life use in mind.
🎯 Who Is This Pump Best For?
Choose the Lacevo S70 if you want:
Strong but customizable suction
Comfort that works across many breast shapes
App control with the option to go manual
Accessories that make pumping away from home easier
A wearable that doesn’t scream “diaper bag pastel”
It’s powerful, functional, and—yes—just a little sexy. (Because sometimes we want our pumping gear to feel more adult than preschool.)
✅ Final Verdict
This pump has officially earned its place in the Genuine Lactation lineup. It’s not just another wearable—it’s a premium, well-designed tool for serious pumping parents who want control, comfort, and a few creature comforts while they’re at it.
