Weak suction, no mist, leaks, and power problems often come from low charge, incorrect assembly, moisture, residue, or normal automatic shutoff. Checking these areas can often identify the problem without opening the device.
This article applies only to the Momcozy BreezyClear™ 2-in-1 Spray & Suction Electric Nasal Aspirator, model NS13. Never open or repair the motor housing.
For regular setup and operating steps, read how to use the electric nasal aspirator.
Key Takeaways
- Weak suction may come from low charge, a poor tip seal, a loose rubber seal, blockage, moisture, or an overfilled cup.
- No mist may be linked to the liquid, tank position, spray outlet, mineral buildup, or six-second timer.
- Wash removable parts separately. Keep running water away from the exposed main unit after removing the collection cup.
- Stop using the device if it becomes hot, smells burnt, sounds unusual, has visible damage, or gets water inside the motor body.

Why Is My Momcozy Nasal Aspirator Not Suctioning?
If your Momcozy nasal aspirator is not suctioning, first check whether the motor is running. A silent motor points to a power issue, while a running motor usually points to a seal, blockage, assembly, or moisture problem.
-
The motor is silent: Check the battery, cable, adapter, charging port, and power indicator.
-
The motor runs but suction feels weak: Check the selected level, tip contact, collection cup, rubber seal, blockage, and moisture.
-
Suction dropped after cleaning: Check whether the rubber seal is missing, reversed, loose, or still wet.
Reassemble the device and test it away from your child. Never test suction on skin, push objects into the airway, or open the motor housing.
Why Does the Motor Run but the Suction Feel Weak?
Weak suction with a running motor usually means that air is escaping or the airflow is partly blocked. The tip, cup, or rubber seal may be loose, or dried mucus may be blocking the passage.
Check these areas:
-
Suction level: Confirm the selected level. Begin low and increase only as needed. Read more about choosing a nasal aspirator suction level.
-
Battery: Fully charge the device.
-
Silicone tip: Attach it firmly.
-
Tip contact: Keep the tip at the nostril opening and reduce large air gaps.
-
Collection cup: Empty it when it reaches about half full.
-
Rubber seal: Check that it is clean, flat, and fully seated.
-
Blockage: Remove visible dried mucus from washable parts.
-
Moisture: Let washed parts dry before reassembly.
The tip should rest at the nostril opening, stay in contact without a large air gap, and never be pushed deeper.
Dry or thick mucus may also reduce suction. Follow the advice in the article on using saline before nasal suction and any instructions from your child’s pediatrician.
Stop if your child develops pain, bleeding, or irritation. Contact Support if suction remains weak after charging, cleaning, drying, and reassembly.
Why Is Mucus Not Entering the Collection Cup?
Mucus may stay inside the tip or aspirator head before it reaches the collection cup. Thick mucus, poor tip contact, a blocked tip, or head movement can also interrupt collection.
Check whether:
- The tip is firmly attached.
- The tip stays at the nostril opening.
- Thick mucus needs loosening before suction.
- Mucus is collecting inside the removable tip or aspirator head.
- Your child’s movement is breaking the seal.
- The cup and rubber seal are loose when suction also feels weak.
A stuffy sound does not always mean removable mucus is close to the nostril entrance. Never push the tip deeper or place another object inside the nose.
Stop using the aspirator if your child develops bleeding, pain, or irritation. Contact a pediatrician about ongoing congestion or breathing concerns.
Why Is the Nasal Aspirator Leaking or Draining From the Side?
Water from the side outlet can be normal during the approved horizontal rinse. Liquid coming from the same area during regular suction or spraying needs checking.
Inspect:
- The cup fill level
- The cup position
- The rubber seal
- The silicone tip connection
- The angle of the device
- Cracks in the cup, tip, or housing
- Moisture near the motor or charging port
An overfilled cup, loose seal, poor connection, or cracked part may cause leakage. Turn off the aspirator if liquid reaches the motor body or charging port.
Contact Support if leaking continues during regular use.
Why Is the Spray Function Not Misting?
No mist usually means the tank is empty, the spray parts are misaligned, the outlet has buildup, or the automatic cycle has ended. Unsuitable water may also leave mineral deposits in the spray system.
Check the spray function in this order:
- Check the liquid level.
- Use only liquid allowed by the current NS13 instructions.
- Make sure the tank and spray parts sit correctly.
- Inspect the visible outlet for residue.
- Clean the approved removable parts.
- Let the parts dry fully.
- Reassemble the spray section and run a fresh cycle.
Current NS13 product information recommends soft or purified water. Hard water may leave mineral deposits in the spray system. Follow the instructions packaged with your device if they differ.
Keep medication, essential oils, homemade saline, vinegar, alcohol, bleach, and descaling products out of the tank unless Momcozy approves them for NS13. Never clean the outlet with needles, pins, or sharp brushes.
Contact Support if no mist appears after cleaning and reassembly.
Why Does the Spray Stop After About Six Seconds?
Mist that runs normally for about six seconds is expected. The NS13 ends each mist cycle automatically.
No mist, uneven mist, or an immediate stop points to a different issue. Check the liquid level, spray assembly, visible outlet, and removable parts. Clean and dry the approved parts before running another cycle.
Never alter or bypass the automatic timer.
Why Did Suction Drop After Cleaning or Reassembly?
Suction may drop after cleaning when the rubber seal, collection cup, or silicone tip is wet, loose, missing, or installed incorrectly. These three parts control the seal and airflow.
Check them in this order:
-
Rubber seal: Confirm that it is present and facing the correct way.
-
Collection cup: Attach it evenly and securely.
-
Silicone tip: Press it firmly into place.
-
Moisture: Make sure all washed parts are fully dry.
Avoid forcing a part or using a similar-looking part from another model. Use the official nasal aspirator setup and cleaning video to check the correct position of each part.
Contact Support if a part no longer fits securely or suction stays weak after reassembly.
Can Water Damage the Momcozy Nasal Aspirator?
Yes. Water may damage the electrical parts if the device is rinsed in the wrong position or submerged.
The NS13 instructions describe two cleaning methods:
- Remove the collection cup, silicone tip, and rubber seal. Wash these removable parts with running water or mild, non-abrasive soap.
- For the assembled rinse, keep the collection cup attached. Hold the unit horizontally as shown in the official video. Rinse the silicone head so dirty water flows from the side outlet.
Never rinse the exposed main unit after removing the collection cup. Do not submerge the device.
If the motor body or charging port gets wet:
- Turn off the device.
- Disconnect the charging cable.
- Leave it unplugged.
- Stop using it.
- Contact Momcozy Support.
Avoid hair dryers, heaters, rice, ovens, compressed air, or home disassembly.
Why Will the Nasal Aspirator Not Turn On or Charge?
A depleted battery, damaged cable, unsuitable adapter, loose connection, or wet charging port may keep the aspirator from turning on or charging.
Check:
- The charging cable and connector
- The wall outlet
- The 5V 2A adapter
- The cable connection
- Moisture or visible debris at the port opening
- The charging indicator
- The time allowed for charging
Keep metal tools, cotton swabs, and cleaning liquid out of the port. Leave the device unplugged if it feels hot or appears swollen, cracked, or wet.
Contact Support if the aspirator remains unresponsive or the cable, port, or charging indicator appears damaged.
Why Does the Aspirator Stop During Use?
Stopping after the normal timer ends is expected. Current NS13 product information describes a six-second spray cycle and an automatic stop after about five minutes of continuous suction.
An earlier shutdown may result from:
- Low battery
- An overfilled cup
- Blocked airflow
- Moisture after cleaning
- A loose part
- Excess heat
- An internal fault
Empty the cup, check the airflow, dry the parts, and charge the battery. Test the device away from your child.
Stop using it if it becomes hot, develops an unusual smell, or keeps shutting down early. Never try to bypass the timer.
What Should I Do if the Tip or Airway Is Clogged?
Turn off the aspirator and clean only the approved removable parts. Dried mucus in the tip or visible airway can reduce suction.
Remove the silicone tip, collection cup, and rubber seal. Rinse them with water or mild, non-abrasive soap. Check only the visible airway, then air-dry and reassemble the parts.
Keep pins, toothpicks, cotton swabs, brushes, and compressed air away from internal channels. Contact Support if residue remains in an area that cannot be safely reached.
Why Does the Aspirator Smell or Have Dried Residue?
Odor and dried residue usually come from mucus left in the tip or cup, delayed cleaning, or parts stored while damp.
After each use:
- Empty the collection cup.
- Remove the washable parts.
- Rinse away visible mucus the same day.
- Use mild, non-abrasive soap if needed.
- Air-dry all parts before storage.
Avoid bleach, alcohol, vinegar, essential oils, descaler, and boiling water.
Replace any removable part with lasting odor, residue, discoloration, cracks, or mold-like material. Contact Support if buildup is trapped inside the main unit.
What if My Baby Cries, Turns Away, or Breaks the Suction Seal?
Head movement can break the seal and make suction seem weaker than it is. Pause the session instead of increasing suction or pushing the tip deeper.
Let your baby hear the device before placing it near the nose. Use the built-in light or music if it keeps your child calm. Keep each attempt short. A second caregiver may gently support the child’s head and body.
Never use forceful restraint. End the session if you cannot maintain a safe position.
Stop suction if you see bleeding or irritation. Contact a pediatrician if your child appears to be in pain or has trouble breathing. Read more about safe nasal aspirator use.
When Should I Replace a Tip, Seal, or Other Part?
Replace a removable part when it no longer forms a secure, clean seal. Cracks, warping, loose fit, or lasting residue can affect suction and hygiene.
Replacement signs include:
- Cracks or tears
- Warping
- Lasting discoloration
- A loose fit
- A damaged sealing edge
- Odor or residue that remains after cleaning
Use parts made for model NS13. The official BreezyClear replacement heads contain silicone parts for the BreezyClear model.
Ask Support before using a part with unclear model compatibility.
