Twee Go Grey Concrete Breast pump

The massage mode offers 5 levels, while the milk expression mode offers 9 intensity levels. Massage simulates the initial sucking phase during breastfeeding, while expression simulates the deeper sucking phase. You can change the level using the increase and decrease buttons.

First, fit the silicone funnel onto the T-piece and check that its flange is properly attached. Then place the membrane on the T-piece, fit the membrane cover and gently insert the suction valve fully into the lower opening. Screw the bottle onto the T-piece, insert the tube into the opening in the membrane cover and connect it to the main motor. The tube should be inserted securely to prevent air leakage. For double pumping, repeat the assembly process for the second set and connect the tubes to the device using the connector.

Before use, check the assembly, disinfect the parts that come into contact with milk, wash your hands and press the breast pump firmly against your breast to create a seal. Switch on the device by briefly pressing the power button; massage mode will start automatically. After 3 minutes, the mode will change automatically. You can also change it earlier using the button. Use the level buttons to select a comfortable massage or suction level. The device switches off automatically after 30 minutes of operation.

After expressing, seal the container of milk immediately and place it in the refrigerator. At room temperature of 16–29°C milk can be stored for up to 4 hours, in the refrigerator at 4°C for up to 48 hours, and in a freezer below -4°C for up to 3 months. When freezing, fill the container to ¾ of its capacity. Do not refreeze thawed milk or add fresh milk to frozen milk.

Warm the milk in a bottle warmer or in warm water at a maximum temperature of 37°C. After thawing, it is best to place the milk in the refrigerator first and then warm it. Do not use a microwave or boiling water. Before feeding, gently shake the container to mix the milk evenly.

When the battery symbol shows one bar, connect the USB cable to the breast pump's power socket and connect the other end to a USB power adapter. The USB power adapter is not included. Once charged, the battery symbol lights up and shows three bars. The device can be used while charging, with particular caution.

First, check the battery charge level and connect the breast pump to the charger. Also make sure that the cable is correctly connected to both the device and the power supply. After checking the connection, try switching the breast pump on again.

Check that the suction valve is fitted correctly and that the breast pump is sealed firmly against your breast. You can place the valve in boiling water for 3 minutes and then fit it again. Also check the battery charge level. If the room temperature is below 15°C, leave the device switched on for approximately 30 seconds before use.

Reduce or adjust the massage or suction level to suit your comfort. You can also change your position or the way your breast is positioned. If the pain or discomfort does not go away, consult a doctor.

After use, disassemble the breast pump and wipe the main device with a dry, soft cloth. Before first use, disinfect the bottle, T-piece, valve, membrane and silicone funnel by immersing them in boiling water for 10 minutes. The parts must be completely submerged and must not touch the dry part of the container. Before the next use, rinse the parts under running water and leave them to dry completely. The tube must be completely dry, and the main device and USB cable must not be cleaned with water or disinfected.
