Eufy S2 Pro - Electric Breast Pump

It is designed for upright use; lying down may cause milk to leak from the collection container.

The pump typically supports 3-4 full sessions on a single charge, with the case providing additional capacity.

The silicone parts should be hand-washed to maintain integrity; do not place the motor unit in any liquid.

Immediately lower the suction intensity and verify that your nipple is centered in the flange tunnel.

It is recommended to replace silicone valves and membranes every 1-3 months, depending on frequency of use.

Check that the silicone valve is not torn and is properly seated. Ensure the flange is aligned correctly on the breast.

Ensure the device is fully charged in the case or that the battery contacts are clean and free of debris.

Verify the device is sufficiently charged, as the heating element requires significant power and may be disabled when the battery is low.
