Disassembling
https://youtu.be/88AqHUD2nhY
For initial use, or after each use, disassemble the pumps into parts that can be cleaned or sterilized separately.
1. Step 1: Hold the pump hub with one hand and use the thumb of the other hand to pull the container edge near the spout
outward to release the pump hub from the spout. (Avoid pulling the flange.) Step 2: Lift the hub.
Step 2
Step 1
• The locking mechanism between the pump hub and the pouring spout ensures reliable suction and heating.
2. Remove the diaphragm from the groove.
3. Unwrap the outer ring of the flange, pull the heating pins out of the oval notch, and then pull the entire flange out.
4. Flick the duckbill valve with your finger to remove it.
• The duckbill valve may be slippery after you use it for pumping. Flicking the duckbill valve helps you move it more
easily.
Cleaning and Sterilizing
https://youtu.be/lkIQ_H89qrA
• All components except the pump hub are washable. Clean the pump hub with disinfectant wipes.
• Scrub infant feeding items using the provided clean brush.
• Do not use a microwave to sterilize. High temperatures will shorten the lifespan and cause safety hazards.
• Air-dry all parts thoroughly after cleaning and sterilizing.
Before Initial Use
Sterilize all washable parts by boiling for up to 5 minutes, stirring constantly to avoid the parts sticking to the container and
melting. Alternatively, steam-sterilize for a maximum of 5 minutes. Then remove them using clean tongs.
5 min
Dishwasher
Cooking Pot
Baby Bottle Sterilizer
For Daily Use
Rinse all washable parts with warm, soapy water, then air dry. Sterilize if needed, using the same methods as the initial
cleaning.
Assembling
https://youtu.be/UchwqZQrDlU
Before assebmling, make sure to wash your hands well with soap and water.
1. Hold the bottom of the container up, insert the duckbill valve into the small hole inside the container with your thumb and
index finger and flick it to ensure it does not fall out.
2. Push the flange tunnel onto the container, making sure the heating pins are firmly pushed into the oval notch. Wrap the
outer ring to ensure it is properly assembled to prevent milk leakage.
Heating pins Oval notch
Outer ring
3. Press firmly behind the heating pins for full extension. Heating may fail if not fully extended.
4. Insert the diaphragm into the groove of the container, with the concave side of the diaphragm facing the flange side.
5. Install the pump hub on the top of the container, pressing firmly to seal the gap between the pump hub and the
diaphragm.
Wearing
https://youtu.be/nzC4MHDWaPM
Measurement
Use the nipple measurement card to determine your flange or insert size:
1. Stimulate your nipple until it is erect.
2. Slide the hole over each nipple. Select a hole with a nipple diameter that fits snugly around the base.
3. Get your measurement based on the sizing chart.
• Nipple elasticity can aect sizing. You may need to size down if you have elastic nipples, or size up if you have
less elastic nipples. If you experience discomfort or notice a consistent decrease in output, you may need to
experiment with dierent sizes.
• 15 mm, 17 mm, 19 mm, and 21 mm sizing inserts must be used with 24 mm flanges. 24 mm and 27 mm flanges are
available for your choice.

23-26mm 27mm
* Sizing inserts must be used with 24mm flange.
Use a Sizing Insert (Optional)
To ensure a proper fit, use the Nipple Measurement Card to select an appropriate sizing insert and place the sizing insert in
the flange tunnel.
Wear
1. Slightly lean forward to make sure your nipple is centered in the flange tunnel. The breast pump should be firmly against
your breast.
2. Use a full-coverage nursing bra with a flap to create a tight seal between your breasts and the flange.
Two criteria will help you determine if the breast pump is positioned correctly:
• Whether you feel a noticeable suction that can pull out milk;
• Whether it is comfortable to wear.
If the wearing position doesn't meet either of these criteria, you need to adjust the position of the pump.
It takes a bit of time for your body to adapt to a new pump, so don't be discouraged if the results aren't good at
the very beginning.

• Do not continue pumping for more than 5 minutes at a time if you do not succeed in expressing any milk. Try
again at another time during the day.
• If the process becomes very uncomfortable or painful, stop using the pump and consult your healthcare
professional.
• Do not wear and use the product for over 35 minutes. Consult your healthcare practitioner to understand how
long you should pump in a pumping session.
Stimulation Mode and Expression Mode
• Stimulation mode (also known as Massage mode):
Designed to mimic the initial rapid sucking that a baby does to stimulate the milk ejection reflex, also known as letdown.
This mode typically uses a faster and lighter suction pattern to encourage the breasts to start releasing milk. The goal is to
signal the body to begin milk flow. This mode is usually shorter in duration, lasting for a few minutes, and is the first phase
of the pumping process.
• Expression mode:
After the milk ejection reflex has been triggered, switch to expression mode. This mode imitates the slower, deeper suck of
a baby when it is actually feeding and drawing milk from the breast. Expression mode uses slower but stronger suction to
extract milk eciently. This phase can last as long as the mother needs to pump to empty the breasts suciently, which
can be about 10-20 minutes per session.
Using with eufy Baby App
https://youtu.be/0eWX-TetCos
Your phone is your pumping partner. Enhance your experience with the eufy Baby app.
Manage devices: Rename the breast pumps, select sides, and adjust LED light.
Remote control: Start or stop pumping, adjust suction or heat level, switch between stimulation and expression modes.
Set schedule and session: Remind yourself not to forget to pump. Set a duration or capacity for each session.
Optimize Milk Output with OptiRhythm Technology: Choose from 4 pre-set rhythms and customize your pump by adjusting
suction intensity, speed, and duration to best suit your baby.
1. Max Rhythm (by default): For moms who want the max output. Switch between stimulation and expression modes
multiple times.
2. Natural Rhythm: For moms who appreciate the natural suction rhythm of a baby. Switch between stimulation and
expression modes with a mix of long and short pulls.
3. Standard Rhythm: For moms who prefer a traditional electric pumping suction pattern. Single switch from stimulation to
expression mode after 2 minutes.
4. Gentle Rhythm: For moms who have sensitive nipples. Each suction is carefully calibrated to operate at a slower pace
and with a softer touch.
Tutorial and FAQ: Refer to more detailed instructions or troubleshooting.
Track data: Review your pumping history.
Upgrade firmware: Upgrade firmware when available for improved performance or new features.
Transferring Milk
https://youtu.be/v_HzT9psxSY
1. Pause or turn o the breast pump. Lean forward when taking out the pump to prevent leakage.
2. Remove the pump hub from the container. (Refer to "Disassembling" step 1.)
Avoid disassembling any parts (including the diaphragm) other than the pump hub before transferring milk to prevent
leakage.
3. Leave the container on the table ready for transfer.
4. Tilt the container with the flange up to pour milk. When the pouring spout faces down, tilt further to empty completely.
Lastly, remove the diaphragm if needed to collect any trapped milk under it.
Storing Milk
Storing Breast Milk
Store breast milk in a clean and sterilized milk storage bag or a milk bottle with a sealing cushion, and immediately place in
the refrigerator to chill or freeze.
• Do not freeze breast milk repeatedly.
• Do not mix fresh breast milk with frozen breast milk.
Feeding Stored Milk
Place the frozen breast milk in the refrigerator for one night to thaw. Alternatively, you can use a bowl of hot water to thaw
in an emergency. Once thawed, it must be consumed within 24 hours.
• Make sure to check the temperature of breast milk before feeding your baby.
• Do not immerse the milk storage bottle in boiling water for heating to prevent it from rupturing or cracking.
• Do not use a microwave oven to heat breast milk.
• Discard the breast milk left after feeding.
Maintenance
1. Pump Hub
Modifications of any kind are prohibited. Opening or tampering with the pump hub will void the warranty. If repair is
required, return the pump hub to the retailer or directly to the manufacturer.
2. Washable Parts
The expected service life of the washable parts is 1-3 months. It is recommended to replace the washable parts after long-
term storage or before pumping for your next child.
More wearable breast pumps and spare parts are available for purchase at
