DISASSEMBLE EUFY 11S (SLIM) FOR REPAIR OR PARTS REPLACEMENT

[@楊翔遴]

Replacement part link now gives a 404.

[@AlsAutoandAppliance]

Thank you for the reminder. It is very unfortunate eufy has decided not to provide replacement parts. :(

[@楊翔遴]

@@AlsAutoandAppliance I think they still have replacement parts. After scrolling through many threads, I found the part I was looking for (Side brush motor): us.eufylife.com/collections/accessory/products/t2108111-90 I haven't confirmed exactly what's wrong with my side brush -- it could very well be a gear. But without a 3d printer, buying a motor is likely the cheapest way to go

In the very off chance you read this. I used your video to take apart my robovac 11s. It was loud when turned on like something was stuck or scraping. Checked the vaccuum motor inside but it was fine. Reassembled the thing and it was fixed. Very weird but i’ll take it. Thanks for the help!

Gotta take your wins whether you know how you got there or not. 🙂 Great job!

Thanks , my dust box was not clipped in properly and it sucked up lots of dust and a smar garlic clove into the motor. Made a terriable sound, watched this and dissambled and cleaned everyting. Working great now.

[@AlsAutoandAppliance]

Great job! Except now your robot will have bad breath from the garlic! :)

[@KandyLandKing]

What a great and helpful video! Mine was making a loud grinding noise. Thought something stuck in vac motor impeller. Nope, ended up chewed up gear in side brush assembly. Toughest was the putting on the front bumper back on. Took assembly apart 3 times thinking that was the issue. Finally read the comments and did find the assembly wasn't matched correctly. Thought the top part of the bumper fit inside the channels on the vacuum, nope. Finally success! I just left the bad gear removed and motor unplugged. Now realize maybe it will throw off an error code? Oh well charging now may have to take apart once again to make 4 times taking it apart. Thought replacing belts in our breadmaker was a challenge, this was worse. Once again, thank you again for all your help!😂

[@KandyLandKing]

Just wanted to mention to NOT unplug the motor! It did do some beeping alarms, so it had to take her apart last time, but working well now!

Cheers for the video! My 11s was saying the suction fan was stopped. Static red light and three beeps. Took it all apart and shook out a walnut shell from Christmas that had somehow made it into the fan duct casing! Put it back together and it’s happily scooting along now. :) Thank you.

Turns out that when the bumper doesn’t want to reattach, you should look to see if any of the wires are sticking out of the case. I learned the hard way. Thanks for doing this video, was really helpful.

[@AlsAutoandAppliance]

Excellent point. This has happened to me in the past as well. Glad you got your vac running again!

[@vbcanuck]

When trying to unplug all the cables off the control board, it is a little easier if you take the three screws out first then lift the board just a little to get a better grip on the connectors. Great video!

[@AlsAutoandAppliance]

Absolutely helpful advice! Thank you for the tip and hope you got your vac running again!

[@jppestana1]

I run a couple of these convicts and haven't had to do any majors on them, but I sure have become adept @ cleaning and light servicing them. This was a great exam of the entire unit. Not sure I am up to the task of of a full dissassembly and re-assembly, but it was sure helpful. And, yes to all EUFY owners-dog hair can turn your cool little slave into a helpless, crippled carpet ornament.

[@leocatz]

Thanks so much for this step by step dis-assembly. Very helpful vs. the 'guess as I go method'. I was able to put my 11s back into service, after removing a piece of hard plastic from the motor housing. It no longer sounds like a tank. (I did end up with 2 mini screws that failed to get back where they belong. But, if it doesn't seem to impact functioning, I'll probably let that go. I'm lusting over a room mapping upgrade, anyway. ) Thanks again for making this task easier. It also gave me an oportunity to do a long overdue basic interior cleaning. You know, blow the nasties onto the floor with pressurized air, so the EUFY can vac them up again! HA.

[@AlsAutoandAppliance]

Thank you for sharing your experience! We did have the opportunity to test out one of the latest Roomba models and the mapping feature is just amazing, but the price is pretty ridiculous. Eufy does just as fine of a job of cleaning, in my opinion. :)

[@leocatz]

@@AlsAutoandAppliance I agree on the cost for room mapping. If I can keep my EUFY 11s running a couple hours every night while I'm sleeping... good enough for me and my feline.

[@Tobias-uf2oj]

Thank you for the helpful video. In my case, after I took everything apart and determined it was fine too, I realized there is a bearing *in* the roller brush and that's what had started sounding like it was falling apart. Maybe you mentioned it and I missed it, but for anyone about to embark on taking apart the Eufy it's worth checking the bearings in the brush first. They should soon freely. Nonetheless, I had a good time tearing it apart and putting it back together again, and it still works so that is awesome. Thanks again for putting this together!

[@AlsAutoandAppliance]

I cover the brush in a separate video, so I never thought to cover that in my other videos. Glad to hear you are back in business!

[@bonobonorman9658]

We have two EUFY 11S that scoot around every night at 01:30 am. They start within seconds of each other and cover the house extremely well when we are asleep. Plus we often start them manually (pushing the blue button, or use the remote) as we leave the house because we do find them a tad noisy. Yes, they are noisy and they like to knock on our bedroom door! It can be fun to watch them "ping-pong" around the various rooms until they go "orange-light mode" and quietly start sniffing for their EUFY charging station. They will find it 9 times out of ten ( 10/10 in a small apartment we think...) and soon ready for work the next morning. We clean the "nappy" i.e. the dust collecting box every two three days and honestly, it is a bit scary to see how incredibly effective the pair really are in doing the cleaning job around the house. So no doubts that they clean our floors very well! If you like to be bare-foot or walk around in socks, you do appreciate the smooth feel of clean floors. . The tips I can share is that it is a very good idea to fix the charging-station with Velcro-tape to the wall shirting board behind it. If loose, the Robovac tend to push it around so it may end up out of reach. The other tip is that we don't see much point in using the two removable filters, a HEPA filter and a sponge-mat. We have tossed those two filters and run our two EUFY 11S team with just the one prime screen filter. It is so much simpler to clean and maintain and the power is definitely boosted when running without the two extra sucker-filters. Maybe the additional two filters are worthwhile if a family-member suffers from some airborne allergy? We have found our pair of Robovac a very good purchase and blissfully without silly distractions like Bluetooth and "magic mapping", etc. No thanks because my time is valuable! Besides, the remote control is fine and dandy for any additional commands. Ooh, we got two EUFY's 11S because after a year or so we could not stand the thought of being without one, would it fail on us. But they just keep soldering on together... night after night. Conclusion: They fill their 0.6 litre dust-pans quick and well, nuff said. Except, what else can you ask for?

If you don't get any lights or beeps at all, there is a good chance that your power switch is bad. Try switching the switch several times in succession. Can also try to spray contact cleaner into the switch or replace it altogether. Have a video for that too. Good luck!

I have run the vac without the dust bin. The dirt is then sucked into the fan area causing poor or no vacuum power. I think that this is a design flaw BUT I think that they are a good vacuum.

Great video! I was having the four beeps and red light error, and resolved it with your help. I have zero experience, and yet was able to take the robot apart. I removed the motor of the main brush, which was not moving freely, and sprayed some olive oil (I didn't have WD40) to get it loosened up. I put it back together and it's working great! The only problem is that I have two screws left over. Hopefully it won't cause future problems. Thanks for the detailed video!

[@AlsAutoandAppliance]

Thank you! So awesome you were able to accomplish something new! If you only had two screws left, that's not too bad! There is a good chance they belong inside the brush compartment. Otherwise, it shouldn't cause any issues. Worst-case, you can take it apart again to find out where the screws go. :)

one minor detail. The 360 degree swivel wheel (as well as the one on the dust pan) can be easily removed by pulling them straight out with some pliers. They clip right on. That's not something I knew and that little wheel was becoming very dingy and clumped up with hair. Otherwise this is a gem. Thanks!

[@AlsAutoandAppliance]

Yes, and there is also a sensor in the well where the wheel is. I believe it senses that the wheel is moving (hence the two colors of the wheel). Good tip!

[@GuntherFischer-ix1uq]

Stumbled here too, the wheel didn't come out easily, and I didn't dare to use too much force. The otherwise great movie doesn't cover this detail. Fortunately, there are others to fill the gap: see video #Y6XX8aq_KUk

If I remember right, that assembly just unscrews from the inside under the main board. Normally, the wheel should just pop out with the axle using a flat blade screwdriver. Have never had one completely break before.

@@AlsAutoandAppliance thank you.

[@CrisGonzalez-k4e]

this is an awesome video, helped me a lot with all the pieces, could you go more detailed about the front bumper? since mine it's impossible to put it back, I see that here you play a bit with it and then it's easy to put the screws, but I'm not sure what I'm doing wrong, since in these views is not shown how the bumper is properly aligned

[@AlsAutoandAppliance]

The most common thing that makes the bumper super hard to reinstall is that the upper and lower body halves don't go fully back together due to wires getting pinched. It's really hard to tell, but take a close look all the way around and ensure there are no gaps between the upper and lower halves. Hope this helps and please comment if you get it to work.

How does one remove the front castor. My robot had a little run in with...kitty doo, and it is just a mess, and I want to clean it up. My experience is with a Roomba 360.

[@AlsAutoandAppliance]

So sorry about the poop incident. The caster just snaps out. You can use a flat blade screwdriver. You can see the metal axle snapped into the caster hub. If I remember right, you can get on the inside edge of the wheel and pry till the axle pops out. The hub part has to be either unscrewed from the inside or it might just also snap out. It’s different depending on the model.

I miss Radio Shack too. Even several years before they all closed they downsized and had people working there that only knew how to sell phones. At any rate, sometimes the gear is just on the motor too far and simply moving it out a hair does the trick. As for replacing the gear, unfortunately I have not found a source and have been looking real hard. An alternative is to try to find a used assembly on ebay. I'm looking at trying to manufacture them myself and need to model the gear then have it printed or molded. Might also try a little bit of grease...not too much, though!

@@AlsAutoandAppliance No charging issues. The 18650 batteries are just worn out and cheaper to replace the 18650 batteries and solder them in than buy battery pack. I was just looking for the same circuit board they use for the BMS. I think i found a bms i can use

Liked your video, help me understand a lot about the little Robovac! Just one question, I removed the front little caster assembly wheel, and now I am unable to put it back in. From the look of it, the rod slides right underneath the circuit board. However there isn't anything I saw that keeps the wheel attached. This is very frustrating as now the whole wheel assembly just sits in there and I'm able to remove it very easily now than how I was before :( Any suggestions? Thank you!

[@AlsAutoandAppliance]

Are you talking about just the wheel and axle or the entire assembly? If it's just the wheel and axle, it just snaps in and out. If it won't stay in, it's possible the feature that the axle snaps into is broken off or worn. If it's the entire swivel part, I'll have to take a look at mine and see how it goes together. I will let you know. :)

[@Flash8012]

alsautoandappliance I’m talking about the entire swivel assembly. I took mine out, and now I am unable to put it back in. It just keeps falling out. Thank you for looking into this!

[@AlsAutoandAppliance]

@@Flash8012 Ok. I have an 11 and 11C and both of them have the same caster and I believe the 11S would be no different. The post of the caster is snapped into place. On the board side of the chassis, the post is flush with the hole that it snaps into. It's possible your caster is not snapped in as far as it will go. If it does appear to be all the way in, then the feature inside the hole where the post snaps into is probably broken away. The only way I can see to fix this is to either install setscrews or pins to lock the post into place in the groove or to drill and tap the top of the post to accept a screw and washer to keep it in place. Hope it just needs to be snapped into place. :)

Hello, the first things to check are the power switch (make sure it's flipped to "I" or on and check that the battery is reconnected, both at the connection in the battery compartment as well as where the cable plugs into the main circuit board. Let me know what you find and we'll check a few other things out. Good luck!

Quick question; Can you roll the wheels when the robot is off? My current one (different brand) will lock the wheels in place, making it extremely difficult to clean them. Thanks.

[@AlsAutoandAppliance]

You should be able to. There will be some resistance but should be safe. If the windings of the motor or any of the drive circuits are shorted, that can make the wheels difficult to turn. In general, there will be no mechanical "lock" on any brand of robot vacuum. Hope this helps, and if you have any other questions, please let me know.

[@jansmit4628]

The 4S1P Lithium battery pack has only a + and - connection, so no balancing circuitry. This looks very unsafe to me. This is very normal for NiMh batteries in small household equipment. They fail often after using it for a year due to imbalance also, but mistreating LIpo batteries can lead to hazardous situations. I think Eufy should have added a balance circuit to there RoboVac models. Question 1: What is the function of the round metal plate behind one of the two wheels. Question 2: The sprocket that drives the rolerbrush in my 11S is no longer square in the middle but round. Motor spins fine, but the brush is not driven. Can his part be separately ordered or does it only come with the motor, gear assembly and brush holder plastics? The motor number seems to be RP390-ST/20143/DV, but is the the number for the whole assembly or is there a separate number for the sprocket with the square hole?

[@AlsAutoandAppliance]

Since Eufy is a lower cost alternative to the likes of Roomba etc., my guess is they opted to forgo battery monitoring to save a few bucks. The number on the motor is just for the motor. The whole assembly us.eufy.com/products/t2108111-97 is available from Eufy, OR you could try and print www.thingiverse.com/thing:5368883 a replacement gear. Recommend using resin printing vs filament. Finally, the disc is a 40 gram slug of metal to add more weight to the back. It looks like the location for the slug may have originally been for a speaker. You will notice there are small holes on the underside where the slug is installed. Hope this helps.

There are two options. You can either put a piece of tape over the top of it, or you can unsolder it from the board. If you have the front of the bot facing you, it is the black part with a hole in the center (approx. 1/2" diameter) at the far right corner. You just need to tape over the little hole.

Most of them come apart very similarly and have similar issues. The main differences are in the "hidden" screws. Some models have a screw under the front wheel and some have screws inside the main brush compartment which are easy to miss when they are covered in a layer of dust and debris. Just remember you should never have to force anything apart. If it seems to be stubborn, study the parts carefully and you will usually find that one sneaky screw.

So sorry for the late reply. Yes, the wheel *CAN* come off, but has to be pressed off of the plastic gear on the inside of the transmission.

If that's still too big, might be able to craft a hook tool from a tin can, but be very careful, as that thin metal can be pretty sharp.
