Setup
1. Charging the Pump
Before first use, fully charge the breast pump. Connect the Type-C cable to the pump and a 5V/1A adapter. The battery icon on the display will turn green when fully charged. A full charge takes approximately 2 hours and provides 5-6 pumping sessions or over 2 hours of working time.

2. Disassembly for Cleaning
To clean the pump effectively, disassemble the milk collection components. Separate the milk collector cup from the pump motor. Then, carefully remove the diaphragm, T-junction, duckbill valve, and silicone plug from the milk collector cup and flange.

3. Cleaning and Sanitizing
Wash and sanitize all parts that come into contact with breast milk before first use and after each subsequent use. These parts include the DoubleFit Flange, Milk Collector Cup, Diaphragm, T-junction, Duckbill Valve, and Silicone Plug.
- Use steam/sanitise pot or boiled water.
- Ensure water temperature is ≤100°C (212°F).
- Soak for 5-10 minutes.
- Wipe off excess water or air dry completely before reassembly.
The Pump Motor and Charging Base do not require washing; simply wipe them with a clean tissue or damp cloth.

4. Innovative Heated Base
The heated base gently warms the pump to body temperature (up to 45°C), which can boost milk output by 30% and ease discomfort, especially in cool conditions. It also features self-cleaning and dust-proof functions.

Maintenance & Care
- Regularly clean and sanitize all milk-contacting parts as described in the "Cleaning and Sanitizing" section.
- Ensure all parts are completely dry before reassembly and storage to prevent mold or bacterial growth.
- Store the pump in a clean, dry place away from direct sunlight and extreme temperatures.
- Do not use abrasive cleaners or harsh chemicals on any part of the pump.
Troubleshooting
If the breast pump doesn't work or the suction power is insufficient, consider the following:
- Proper Assembly: Ensure the diaphragm is pressed tightly into the collector and the T-junction locks fully into its slots. Improper assembly is a common cause of low suction.
- Liquid Damage: Gently shake the pump base. If you hear liquid, stop use immediately and inspect the motor vents for moisture. Liquid in the motor can cause malfunction.
- Flange Size: Verify that you are using the correct flange size (19mm, 21mm, or 24mm) for your nipple. An incorrect flange size can affect comfort and milk expression efficiency.
- Battery Charge: Ensure the pump is sufficiently charged. Low battery can lead to reduced performance.
If issues persist after checking these points, please reach out to customer service directly through the Amazon messaging system for professional assistance.
