Nasiboo Nasal Aspirator works fine on low but shuts off on max power


I struggled to find a category but the device works basically exactly the same as a vacuum cleaner. It just sucks air inside to get boogers out of children’s noses.

So I can turn on the device and choose the suction strength from low to high (1-5).

It’s controllled by a turning switch. I can turn it on on 1 and it works like it should. I can change it to 2 and it works too. But after 2 it just shuts off. So between 1-2 it works and between 2-5 it shuts off. If I try to start on a power mode between 2-5 it starts for a second and then shuts off.

To turn on the device you have to press the turning switch. Which goes up and then stays there (if it works properly)

I coulnd’t find anything online about the device and I would have to buy tools to repair it so I wanted to hear a couple of opinions if it’s repairable or not.

So my reasoning is that it’s a faulty switch because if it would be a faulty fuse or electronics it woulnd’t work at all. Since it starts for a second when I press the button to start it, the power flows and when it goes back up it doesn’t get any electricity so it shuts off.

So I think if it’s only a switch I could buy the tools to unscrew it and to look inside. Do you think it’s repairable? (I also coulnd’t find any spare parts for this exact device so I would have to work with what’s available as generic spare parts)

Hi trigonom,

I have the same nasal aspirator model for my children (Nosiboo Pro and it stopped working yesterday, found your post so I thought I’d give you my 2 cents on this.

I managed to take it apart, but couldn’t find the issue yet, note that mine stopped while it was running and I could not start it ever again, so mine probably has a different problem than yours.

Back to your case, if you remove the plastic case you will see the turn switch operates a potentiometer under the hood that controls the power level of the motor hence increasing or decreasing suction power. Your description of the problem tells me your device detects the motor cannot operate safely when you move the turn switch above level 2 and shuts the motor down. This can happen even under normal circumstances eg. if you use the appliance too long and the motor gets too hot, but if you wait a few minutes for the motor to cool down, you can use the application again as normal.

But in your case it seems the safety electronics that’s there so that the motor cannot overheat switches the motor off either 1) because this safety electronics is faulty or 2) there’s something wrong with the motor itself and the safety electronics detects the problem correctly when it switches it off.

So what I want to say is that your turn switch is probably at no fault, but your problem is probably deeper down in the safety electronics (can be cheap to fix if you can identify the problem) or in the motor (can be more expensive). Also, there’s typo in the title of your post ie. the name of the product is Nosiboo (not Nasiboo), maybe more people find this post if you fix that typo and they can give you a better idea.

Anyway, I bought a new one of the same appliance the same day it broke, because my kids need it so much in the winter and I think the quality of this product is excellent and I’ll get back to trying to fix it later. My appliance was about 6 years old when it broke, we got it from friends where it already served their kids.

Hi Dia Kritikus!

May I ask, how did you remove the plastic shell? I’m afraid that I’m going to break it.

Mine stopped working. Last time I used, everything was ok. And now it just makes a tiny ministart and nothing happens. I have never used it without a filter and no one dropped it. It’s less than 3 yo old.

So sorry, trigonom for using your question for finding info, bit seems there isn’t many Q&As about this item.

Hi Helen,

There are 2 tiny screws at the back you can reach through narrow holes you might have mistaken for venting holes. Hope this helps opening the case.

The ministart sound bad. Let me know what you find.

So I had/have a problem with my Nosiboo 2 and since this is the only post I could find about this I will post my findings here.


Final user (2 year old) dropped physiological serum (salty water) on the power button which caused a short and the device was dead.

Disclaimer : this is what I did and if you go on this route I cannot be responsible. Always test with plastic cases closed and the ability to cut power quickly

I live in Europe and power is 220v here.


- Remove plastic shell (torx screws : 2 near power cable input and 2 above it hidden in some deep holes, i used a small flat screwdriver to remove these)

- Inside there are another 4 torx screws that are larger and hold the other plastic elements together

- I have removed everything inside the case : electronic board mounted on the power input , electronic board mounter under the power button and the fan/engine assembly which is wrapped in a dense foam

- After some wrong steps which shorted yet again the circuit boards I have removed all existing electronics and kept only the motor with the power leads that go into it

- Depending on your issue I advise keeping the electronic board connected to the power input

- Going in side the motor there are 4 wires : 2 white which actually power the motor and 2 black which are connected together with what I suppose it is a thermal switch that prevents the motor from overheating

- I have connected one wire from the mains to a white wire , one of the black wires with one of the whites and the left black wire with the left wire from the mains. Connections where done with Wago 221

- At this point the motor will go with it's full 500W and probably pull your brains out (really doubt)

- To power in a more controllable way the device I used a Gewiss GW20803 and a Gewiss GW20203 in a Gewiss GW27002. Power cable with shucko on one end . Other end connected with grounds and one line to the power plug and one line connected to the variator. Other side of the variator connected to the power plug.

In my use case motor starts at about 1/3 of a spin and you can use it with one rotation step up.

Motor code : px-(d-1)-500

Thermal power switch : BM-1 0954 1324

I will get back when and how it eventually died.

Notes :

  1. Very hot air is coming out. Not sure how it was before
  2. Not sure how long this hack will last but considering only the bought parts and not the tools this was 10% of the entire price of the unit.

Seeing some information about that product, I hope my post will fit here.

As a user of that impressive tool, I am searching for

- information about how much physiological serum can be held by the official paper filter before the fan / motor may be damaged... Photo of the inside parts for clues about that worry as mine is still under warranty and work fine for now.

- a filter like the hospital ones to put between the machine and the head. It looks like a cylinder with both in and out tube on top, and I believe it will be a perfect way to prevent that risk

And I can tell the vents are pretty hot when operating, so it is normal.
