Setup
1. Initial Cleaning
Before first use and after each use, disassemble all parts that come into contact with breast milk (silicone flange, milk collector cup, diaphragm, valve). Wash them thoroughly with warm soapy water and rinse with clean water. Sterilize these parts by boiling them for 5 minutes or using a steam sterilizer. Do not wash or sterilize the motor unit.
2. Assembly
- Ensure all parts are dry before assembly.
- Carefully attach the valve to the bottom of the milk collector cup.
- Place the silicone diaphragm onto the milk collector cup, ensuring a tight seal.
- Attach the silicone flange to the milk collector cup, making sure it is securely fitted.
- Align the assembled milk collector cup with the motor unit and press firmly until it clicks into place.
3. Charging the Device
Connect the USB charging cable to the motor unit and a suitable USB power adapter (not included). The battery indicator on the display will show charging status. A full charge typically provides 4-5 pumping sessions. Charge the pump fully before its first use.

Operating Instructions
1. Wearing the Pump
Once assembled, place the breast pump directly into your nursing bra, ensuring the silicone flange is centered over your nipple. Adjust your bra for a secure and comfortable fit. The hands-free design allows you to move freely during pumping.

2. Power On/Off
Press and hold the power button on the motor unit to turn the pump on or off. The digital display will illuminate.
3. Mode Selection
The pump features 4 modes. Press the mode button to cycle through them:
- Massage Mode: Stimulates milk let-down with gentle, rapid suction.
- Expression Mode: Mimics a baby's natural sucking rhythm for efficient milk extraction.
4. Suction Level Adjustment
Each mode has 9 adjustable suction levels. Use the '+' and '-' buttons on the motor unit to increase or decrease the suction intensity. Start with a lower level and gradually increase to a comfortable, effective setting.
5. Pumping Session
Pump for approximately 15-20 minutes per breast, or until milk flow significantly slows. The pump operates quietly, with a noise level below 40 dB, ensuring minimal disturbance.
6. Milk Collection
The milk collector cup can hold up to 180 ml of expressed milk. Monitor the milk level during pumping. Once finished, carefully remove the pump from your bra, detach the milk collector cup, and transfer the milk to a storage bottle or bag.

Cleaning and Maintenance
1. Disassembly
After each use, gently detach the motor unit from the milk collector cup. Disassemble all parts that come into contact with milk: the silicone flange, milk collector cup, diaphragm, and valve.
2. Cleaning
- Wash all disassembled parts (except the motor unit) immediately after use.
- Use warm water and a mild dish soap.
- Rinse thoroughly with clean water to remove all soap residue.
- Do not use abrasive cleaners or brushes that could damage the silicone or plastic components.
3. Sterilization
Sterilize the cleaned parts (silicone flange, milk collector cup, diaphragm, valve) regularly, especially before the first use and once daily. This can be done by:
- Boiling: Place parts in a pot of boiling water for 5 minutes. Ensure parts do not touch the bottom or sides of the pot to prevent damage.
- Steam Sterilizer: Follow the manufacturer's instructions for your steam sterilizer.
4. Drying and Storage
Allow all parts to air dry completely on a clean surface or drying rack. Store the clean, dry components in a clean, covered container until the next use. Keep the motor unit dry and clean with a damp cloth if necessary.
