How to Use eufy S1 Pro Breast Pump with Milk Bags

What the eufy S1 Pro Breast Pump and Milk Bags Deliver

The eufy S1 Pro Breast Pump is a heated wearable pump that uses HeatFlow technology to help prevent clogs and boost output by 30% (based on feedback from over 300 eufy pump users). It comes with a wireless charging case that provides up to five days of power, making it suitable for pumping on the go. The included eufy Milk Bags (120 pieces) are pre-sterilized, thickened bags with double-sealed seams and double zippers to protect milk. They also feature color-changing technology that lets you see the milk's temperature at a glance: purple means too cold, white means too hot, and blue means just right for feeding.

This guide walks you through using the pump with the milk bags step by step, from setup to sealing and storage.

Step-by-Step: Using the eufy S1 Pro Breast Pump with Milk Bags

Follow these steps to pump and store milk efficiently using the eufy S1 Pro and its compatible milk bags.

1. Charge the pump and prepare the milk bag: Ensure the S1 Pro is fully charged using the wireless charging case. Open a new eufy Milk Bag; the bag is pre-sterilized, so no additional sterilization is needed. Check that the double zipper is clean and undamaged.
2. Position the pump and start pumping: Place the S1 Pro over your breast, ensuring a comfortable fit. Use the eufy Baby app to customize pumping rhythm, suction, and speed with OptiRhythm technology for a hands-free experience. The HeatFlow feature provides gentle warmth during pumping.
3. Transfer milk to the milk bag: After pumping, carefully pour the expressed milk into the milk bag. Each bag can hold up to 7 oz, reducing the number of bags needed. Leave some headspace to allow for expansion when freezing.
4. Seal the bag securely: Press the double zipper closed with your fingertips until you hear a click. The double-sealed seams and double zippers provide a strong, leak-proof seal. Double-check that the zipper is fully engaged.
5. Check the temperature indicator: The milk bag's color-changing technology shows the milk's temperature: blue means just right for feeding, white means too hot, and purple means too cold. Use this to decide if the milk is ready to feed or needs warming or cooling.
6. Store or feed immediately: If not feeding right away, label the bag with the date and store it in the refrigerator or freezer. The strong seal helps protect the milk from leaks and contamination.
