How It Works
- Assemble & Sterilize: Connect the duckbill valve, diaphragm, milk container, container back, and flange. Before first use, boil washable parts for up to 5 minutes or steam-sterilize for up to 5 minutes.
- Charge: Fully charge both pump hubs before use. Place them inside the S2 Pro charging case and align the magnetic charging pins until the indicator confirms charging.
- Fit & Align: Place each pump inside a supportive nursing bra with your nipple centered in the transparent flange tunnel. Use the built-in nipple light to help achieve proper alignment and a secure seal.
- Power & Customize: Turn on the pumps and connect them to the eufy app. Adjust suction, HeatFlow™ 2.0 warmth, VibraPump™ massage, rhythm, and pumping modes to suit your comfort.
- Pump Hands-Free: Begin your session and move through your day while the pump works discreetly. Smart sensors can alert you to potential leaks and stop pumping when the milk container is full.
- Clean & Store: After pumping, transfer your milk, disassemble the 5 washable components, wash thoroughly, and allow them to air-dry completely before reassembling or storing.
