Why consider it

  • Integrated motors keep the setup inside the bra without routing external tubing.
  • Three included insert sizes offer documented options to check alongside the 24 mm flanges.

What to consider

  • The original M5 does not connect to the Momcozy app; M5 Smart is a different model.
  • The pumps cannot operate while charging, and the documented kit does not include a wall adapter.

Check the seal before starting

  1. Start with clean hands and clean, fully dry collection pieces. Seat the diaphragm on the collector and press its edge into place.
  2. Fit the valve onto the flange without a gap. Align the heart marks on the flange and collector, then press around the flange rim.
  3. Attach the motor last. Check the breast seal and nipple alignment before securing the pump in your bra.

These steps apply to the original M5. A loose connection can disrupt the seal; increasing suction does not fix an incorrectly assembled cup.

Switch off, remove and transfer

  1. Switch off, then use a finger to break the breast seal.
  2. Lean slightly forward as you remove the pump, keeping the flange opening facing up.
  3. Hold the protruding sides of the motor to separate it from the collector before pouring. Pour gently into a milk-storage container.

Close and label the container using the storage guide, then clean and fully dry the collection pieces. Stop if pumping hurts and seek qualified help for persistent discomfort.

Prepare for the next session

Keep the motor and charging equipment out of wash water. Charge between sessions: the original M5 cannot pump while charging. Unplug it and close the charging-port cap before use.
