Eufy S1 Wearable Breast Pump – HeatFlow™ Comfort and Smart App Control

Because pumping should be as natural and stress-free as possible, the Eufy S1 Wearable Breast Pump combines gentle heat therapy, hospital-grade suction, and smart app control—helping moms pump comfortably, quietly, and efficiently anytime, anywhere.

The Eufy S1 Wearable Breast Pump is a revolutionary advancement in wearable pumping, designed with moms’ comfort and efficiency in mind. Its exclusive HeatFlow™ technology warms the soft silicone flange with uniform heat (35°C – 40.5°C), boosting milk flow, easing letdown, and preventing clogged ducts. With seven adjustable heat levels, every session can be tailored to your comfort.

Using OptiRhythm™ technology via the Eufy Baby app, you can remotely control suction strength, rhythm, and speed for a fully personalised hands-free pumping experience. Its ergonomic 105° flange supports natural milk expression while accommodating nipple sizes from 17mm to 24mm. Delivering up to 300 mmHg hospital-grade suction, the S1 maximises output while staying gentle on your body.

Discreet and practical, the S1 is lightweight and fits comfortably in-bra with a secure leakproof double-seal design. At just 46 dB, it ensures privacy at home, work, or on the go. All skin-contact parts are BPA-free and food-grade, while washable components are dishwasher safe or suitable for boiling, steaming, or UV sterilisation.
