Xiaomi Roborock S50 - real fan repair (not replacement!)

Instruction for repair of damaged fan when you start smell burned plastic. Called as an Error 18.

[@chimeranzl9147]

Genius! Thanks for this - threw in a couple of washers and it did the trick perfect! Also found fluff clogged up on the intake so cleaned the whole inside, it's cleaning the floor ten times better now, just like new!

[@NLRamonNL]

Awesome, thanks a lot. I hope you sleep well tonight knowing there is another roborock S5 driving around with pieces of credit card in its fan motor. For those attempting this: The clips on the fan motor break really easy. I had to resort to a drip of glue to ensure a good seal

[@tomasnovotny5892]

You are welcome, I'm glad it works and helped you, my sleep will be way better now!!! :-))

[@NLRamonNL]

1.5 year update: it happened again, i ordered a new motor this time.

Dear Tomik, thanks for the very helpful video! We used BN1074 washers we had left over from our raspberry pi, and they work just fine. Our fan casing clips snapped off when opening them, so we superglued the halves together. Our vacuum is finally working again! The problem presented itself a little differently for us: fan would spin up very slow and after a few seconds error 18 (fan error) was returned. No burn smell, no skidmarks found in the fan. Since we didn't find any debris either we gave your method a try. Good luck to all others with similar issues!

[@stefl0n]

My fan also got stuck the same way and so I was able to repair it easily with your solution. Thanks a lot! :-)

[@Mizmodigg]

I can confirm this works. Fixed my fan this way and it is running fine so far. Though, I found a local seller of fan-replacements, so I now have 3 working robot vacuums....

[@menangal]

i got exactly the same problem with my robot vac. it sometimes stopped and produced burnt plastic smell. already bought a fan replacement but then found your clip. while waiting for the replacement i tried what you suggested and voila ... it worked like magic!! the robot vac is now back like a brand new one. i will keep the replacement for spare. thank you very much for sharing!

[@vithayab2286]

I have the model vacuum + mop 1G. Seems to a be another version. Bought mine 1month ago, it was working well until today. I did the same trick with the fan and it worked ! 1g fan is black, not white. Thank you for your tutorial

[@Tomik723]

You are welcome, I’m happy, it worked for you too.

[@Lopatoid]

Thanks! Roborock S5 was giving me "fan error" and I was able to fix it with a help of your video.

[@danijel124]

Thanks this actually works. I used metal m3 washers. I couldnt remove the stator like you so i just placed it underneath somehow and it works again :) thanks

[@robertcmarko1829]

Thanks Tomik723, This definitely works for me. I made those distance parts from shirt collar stay, which is thinner than and I found it better this way. Good job!

[@robertcmarko1829]

...thinner than plastic card...

[@chrishamilton2694]

You're a genius! Awesome video! I wish I had that ingenuity.

[@viniciusperotto594]

I must have done something wrong. One of the clips broke, then I put the washers and closed the vacuum. When I turned it on the fan started making a very loud noise and it didn't look safe to let it run with that noise, so I sort of gave up and let the robot to die alone in my living room. Later I ordered a new fan from aliexpress, which was like $10, had a coupon so it cost me $3 with free shipping. I kept the original fan, if the new one breaks I will try your fix again! Thanks for sharing the video :)

[@Tomik723]

Did you checked if the fan seats well in position without freeplay? I don’t know if housing connection is tight enough when one clip is broken, but you can always weld or glue it (disassebly will be more complicated next time, but it will serve the purpose).

[@m.willms3471]

It worked. Thank you so much!

[@danijel124]

I repaired 4 roborock s5 this way and they work as new after 1 year :P Thanks mate

[@tomasnovotny5892]

Thanks for feedback! I'm glad it helped! :-)

[@NhanHuynhDo]

Another success story. I used layers of toilet paper instead of washers to have more control of the thickness. Thanks Tomik723 for the tip!

[@Tomik723]

Good idea! Anything with needed thickness can be used :-)

[@patrickgorham966]

Worked GREAT, Many Thanks!

[@tobybrown1179]

My fan glued itself together on the flange near the motor. I had a new fan to exchange it over so just threw it away, after pulling it apart to check it out. Yes the tags broke off easily as I pulled apart

[@vanameintani3708]

Thank you very much! You are great!

[@robi7155]

Hi Tomik, thanks for this video *thumbsup*, i had the same problem and i could solve the problem. My Roborock smelted like it was a electronic failure, but after i saw your video i checked this little guy. And what can i say....... see it, say it, fix it and it works like new!

[@joelity]

I opened the fan and found that the motor core and the blade was not firmly attached to each other. When the blade spinning, it floats up a little bit till stuck to the fan cover. My working solution is using super glue to attach the fan blade and the motor core. Making it stick together. The robot is working just fine.

[@Mizmodigg]

This looks just like mine. I had noise in addition to the smell. Did it work fine after your fix?

[@alexmendel1324]

nice guide, made same with my old original engine after watching your video. Can't test helped this or not until my current engine die, too lazy to disassemble robot again just for tests :/ But already touched this previously floppy detail, it not loosy anymore, seems legit! Sad that I've found this video too late and already buyed new engine from aliexpress... What have you used to open those clipses? I've break two of them at opening

[@shaundramann9161]

God bless you! Thank you!

[@njmaverick7]

Hey @Tomik723, I was wondering if you know the pinout for the motor connector on the board. I believe one would be +14V, GND, two others for the direction I/O.

[@Skans-Gustav]

Beautiful solution! Thanks.

[@mattagren]

Fantastic!!! ❤

[@khanhbber]

Can it work on S5 Max, S6 MaxV ? tks

[@ivanj0]

Well thought!

[@BOTmaster15]

3d printing one custom washer would be much easier to assembly. Mine is still workign but sooner or.later I might have to do this

[@tomasnovotny5892]

Thanks for feedback, glad it works! :)

[@alptekinkaratas1772]

thanks a lot.

[@cescsoo]

good idea👍

[@tubaengin]

I have been using s5 for 1.5 years now and it alvays gives error 10 like 2 minutes after it starts cleaning. It decreases the suction power and does not clean as good as before. Also it keeps calling for error 5 during cleaning like every 5 minutes. It complains more than me during cleaning 😅 i disassamble it till the fan and cleaned all filters but nothing changed. Do you have any suggestion about what to do? Thabk you for thr video, i will try of it helps for our case..

[@Tomik723]

Uff, unfortunately no idea, sorry. So far I had a trouble only with a fan.

[@pinidpm]

Hi, I had the same problem than you. I cleaned my roborock and after 1 minute cleaning, the Error 10 appears again. I changed the vacuum motor of a new one and the problem was fixed!

[@tubaengin]

@@pinidpm thank you. I try it too. It is quite expensive nowadays because of the currency rate but insallah I will try it in first opportunity.

[@wizard-of-other-oz]

Did not help. It seems the magnets cannot hold the turbine in place

[@andriuspajarskas1084]

simple and good solution, funny indian accent too :)

Thanks Andrianus, I’m glad it works! BTW it’s Czech accent xD

I removed the 3 screws but cant remove the pcb from the Fan?! How to remove the pcb?

[@sagarspatil]

Same problem with my Roborock s5 max. Can’t separate the circuit from the fan.

[@zsoltkallos437]

@@sagarspatil same here. did you find the solution?

[@sagarspatil]

@@zsoltkallos437 yes. Watch the video in slow motion and follow it closely. I’m not sure how to explain it.

[@zsoltkallos437]

@@sagarspatil can you try to explain, still cannot disassemble :(

[@elczupakabra8993]

I had the same problem, but I have just used more force and it finally came off. To not break anything just hold the metal part on the PCB and the base part of the fan (closest to the PCB) as the top part can be dismounted.
