FAQs
Why is the eufy Wearable Pump S1 better than other pumps?
The eufy Wearable Pump S1 features industry-first HeatFlow™ technology for improved milk flow and comfort, hospital-grade suction, and OptiRhythm™ smart customization. It delivers an efficient, comfortable pumping experience paired with an app for remote control & data tracking, and a full accessory kit.
Why heating, and is it safe to use?
Heating increases milk output and comfort. Our embedded HeatFlow™ system uses a precision sensor that checks every 3 seconds to maintain optimal heat (95–105°F). You get 7 heat levels, a 5–15 minute auto-shutoff timer, and all parts are BPA-free silicone. The heating flange has passed 56 hours of continuous boil and 1,000 flex tests.
What are the warranty and return policies?
• 12-month warranty on the pump hub
• 3-month warranty on all washable components
Returns accepted only if unused, unopened, and in original packaging.
What accessories are included, and are replacement parts available?
• 2 pumps with 24 mm flanges
• 17/19/21 mm silicone inserts
• 2 magnetic charging cables

• 1 storage bag, 2 dust covers, cleaning brush, and user guide
Replacement parts for all washable pieces are sold separately.
Do wearable breast pumps decrease milk supply?
No—when used correctly, the S1 Pro can maintain or even boost supply. Its ultra-quiet motor, adjustable suction, and heating feature mimic natural nursing patterns and help stimulate let-down.
