Why can't I feel much suction?
Breast pump suction is limited to 40 kPa by international standards to protect breasts and capillaries, so the suction may feel soft. If you're using a new pump, check it's working properly and you've set the right mode for optimal performance.
-
How to ensure proper heating for S1&S1Pro?
Make sure the heating pins are fully extended, the pump hub is securely attached, and there's no gap between the hub and diaphragm. Press the heating button. If you see a solid orange light, the heating is on. If it flashes orange, repeat the steps.
-
What should I know about charging S1&S1Pro?
Use a magnetic charging cable with a 5V/2A or higher rating adapter. S1Pro can also be charged via the charging case. When pump and case are fully charged, use without heating for 20 mins/session, 3 times/day, the case can last 5 days.
-
Can I use a microwave to sterilize eufy breast pumps?
No, it can damage the components and cause malfunctions. Initial Use: Steam washable parts or boil with constant stirring for up to 5 minutes. Daily Cleaning: Rinse washable parts with warm, soapy water and air dry. Sterilize as needed.
