My wife just purchased this exact unit from a garage sale and I found this extremely helpful to me in taking apart and thoroughly cleaning it.

This video is fantastic. I don't think there's another U1 teardown/repair video on KZfaq that really goes into this kind of detail, especially the more convoluted parts of disassembling one of these machines such as the wheel timing, belt drive assembly/tension, location of fragile clips, order of assembly etc. Great job, I'll be referencing this video in the future for sure.

HUGE THANKS for taking the time to do this tutorial! I know you kept saying to take it to an authorized dealer and trust me I thought about it but... I just kept watching and performed all of the repairs myself using OEM parts sourced online. Thanks again!

Great video ! I own a U1 and take great care when using it. Fascinating to see how intricate the engineering is on these units. I'm skeptical if my authorized Miele dealer would be able to service the unit with the same expertise that you have.

I watched the whole thing from beginning to end! Very entertaining & I learned quite a bit!

Thank you so much for this detailed disassembly and repair guide! I used this, as well as your motor disassembly video to overhaul an S7260 Cat and Dog that was almost ruined because the were running it with the bag holder missing. The inside was a mess, the motor was all filled up with pet hair and dust. Its all spotless now and running great.

I have an issue only with the lower unit. Lower unit has no vacuum. Hose has full vacuum and no ports are clogged anywhere. I wonder if the hose position you showed somehow in the lower unit is not in the correct seal position. I have not taken the lower unit apart yet so can't imagine how that would happen without it being opened up.

Your fantastically useful video production is a gift that keeps on giving. I suspect there will be more folks discovering this now that the U1 S7 vacuums are out of production. I just fixed my 2010 vintage S7210 with a few new parts and hope it lasts another 10 years. ;-)

Its interesting on how miele engineer the S7/Dynamic U1. German engineering at its finest.

37:40 THANK YOU SO MUCH. You just saved me a trip to the repair shop. I just finished cleaning the beater bar assembly (two long-haired adults and a couple of long-haired cats make for a very sad beater bar) and went to put the unit upright again, but it jammed and wouldn't lock upright. A web search indicated that this ribbed shield was likely the problem, and I discovered that it was quite loose inside the housing. I managed to pull it out and verified that the vacuum could now lock upright, but I couldn't for the life of me see how it was supposed to be secured inside the swivel head; I was pretty sure I'd have to take it in for repair. Your video solved the mystery; I was able to get that shield back where it belonged and working properly again without binding up the works. Thank you!!

Great video, can't wait to watch it again tomorrow. Our s7580 seems very similar and had the red light come on and stopped all vacuum. Bag seems to not secure right and debris was everywhere.

Thanks. I couldn't figure out how to get the cover back on. Your video saved me a trip to the vacuum dealer!

Thanks for posting the video! Its great to be able to watch someone take apart the machine. Had a hard time getting the handle to tilt, and it turned out my wheel timing was messed up. Found a broken off tab on the bottom motor cover and I think the sliding dust cover must have jammed causing one side of the wheels to go out of sync. The part showing the timing marks was a little blurry, but once I got it apart and it made sense. Had to reposition one of the gears but once it was adjusted the handle tilted smooth as butter! Removed the sliding cover since it doesn't prevent the vac from working. Definitely German engineering at its best and kind of complex. Very solid, though, compared to the throwaway vacs they sell in chain stores. Have had it about 7 years and filtration/suction are awesome. Had a Panasonic before that fell apart within 5 years.

Have owned several s7s in the past and currently have a yellow s7210 - lovely machine Your video has been an eye opener for me - very informative and helpful I do wish they'd continued with s7/u1 development as we might have still had production examples to this day and who knows maybe a newer model even!I see these as a sebo rival In many ways ( got the sebo X7 too)

Wonderful job and exactly what I needed. Thank you!

Learned a lesson the hard way. Reassembled after cleaning and didn't push down hard enough on the motor retention wedge or whatever it's actually called. Within a year the belt had worn out from being too loose and slipping on the drive sprocket, essentially stripping all the belt teeth off of the belt. New belt with the motor retention wedge pushed firmly downs far as it would go and it's running like new again. Thank you for sharing your expertise!

4 minutes into the video and he had it solved. A Sharpie marker was stuck where the hose attaches to the vacuum. This then captured hair, dust, etc and completely blocked it up. Once removed, it ran like new. Thanks!

Miele twist 300 has grinding noise when in twist while vacuuming.Thanks for the great video!

Keep up to great work on the videos

Thanks for the video! I just removed a bunch of caked up dust from below the chrome plate on the bottom of my S7 Tango and a bunch more from the intake tube. There were two metal "clips" inside the tube that seemed to catch most of the dust and that was the source of the blockage. Do those clips belong in there are did I vacuum them up at some point and they got stuck?

Excellent and comprehensive video - thank you and well done. Do you have a detailed guide on the wheel timing for this model please?

Hi great video did you manage to upload miele wheels timing video i’m still having problems getting the timing to work many thanks 🙏

video was awesome..u make it possible for owners to repair instead of outrageous repair bills

Crazy thorough! How does one send you their Miele?

Great video! Mine is very loud and spewing a fine beige color dusting on the front bottom. I’ve taken it all apart and cleared all of the air flow areas including taking the bottom plate off. I installed a new bag and filter. It does vacuum and picks up anything on th3vrug. Any idea what’s causing this? Thank you for any advice you may have!

I have this vacuum but its the blue one I guess a step down from this one. I would send it to you for a check up but that a distance to go I believe. I would take it apart as I have a many a vacuum but this one is its own beast.

Hi, What is the best oil that you recommend? Just got a Miele Salsa that's in rough shape but I hope to fix it up.

I have this vacuum and got one open box on eBay in 2018, but since cleaning my car a few months back, it’s developed a higher pitch sound as if something is blocking airflow. I’ve taken a broomstick and cleared the extension hose, but the sound is still there making me wonder if there is a blockage in the head unit? I’ve checked the brush rollers and the suction hose inside and it seems clear.

Awesome video dude. These Miele uprights seem to get a decent amount of hate on the subreddit but I still had to have it when I found out they had one S7580 left at a different vacuum shop I went to today.

A mostly excellent video but a few vital points, especially the re-installation of the wheels, are not in the field of view of the camera. Also around 40:40, music starts which replaces what appears to be vital dialogue about wheel re-installation and timing which lasts until 42:40. What in the world is that about?

Is silicone based grease suitable for the component at 49:30? I bought a used Twist and wanna go through it of course

Awesome video bro

Great video except a couple times you didn't show what you did like the handle removal. Very informative video all in all, thank you.

I was wondering if you could tell me which wires go to which terminals on the connector in handle(3 wire) red black white? I accidentally pulled wires from connector while removing top handle incorrectly :/

Great video. Love that it's literally looking over the shoulder of a trained professional as you explain what you're doing. I have two questions: 1) Removing the electrical handle: you mentioned a T20 into the hole. Is it a push latch or a screw? 2) You mentioned he hose tab breaking and being under warranty. This is the first I've heard about it being under warranty. Mine is held on with tape after breaking within the first year. Are you saying that I should be able to take the vacuum to a Miele repair shop and have that part of the housing replaced under warranty?

Thanks for the tutorial! I bought one of these secondhand and when removing the brush roller it was missing one of those side springs. Any idea where these can be purchased? Thanks!

I need to replace that black plastic piece that is rounded that you just took off. Do you know where I could find one and what it is called

How would I contact you to get my Miele S7280 repaired? The carpet feature works intermittently and mostly only when handle is held at certain angle? Thanks! Love your channel!

We now have 3 of these, first one had a very large blockage, all good now, thank you for this, a very good job. Why do they not make these, any idea?

Thanks!

How does one know when the suction motor is broken? I am getting barely any suction ... even from the elbow ... nothing is blocking the elbow ...

What is the name of the part that he removes at 5:28?

Hi, I bought this brand new 7 years old and it just started having problems staying up. The lock height foot mechanism won’t stay. I brought it to my local shop that I bought it from and they basically said it’s time to buy a new one. They attempted to repair and said it would cost $250 but would still lean and could potentially have problems in a few months. They didn’t feel comfortable charging me that and doing the repair since it wouldn’t be 100% fixed. My question is can it be 100% fixed? Do I need to take it someone else or try myself? Or is it truly time to trade up. Was thinking sebo this time after watching your reviews

When reassembling my Twist, I was unable to get the top to click on to the bottom.....the problem turned out tot he the plastic piece /insert that sits between the two. When I removed that piece (the ends of it were bent and in bad shape....however I have a big black pliable gasket (kind of) that I didn't see in your demo. Do you know where I might buy a replacement for that piece/ and /or what that piece is called. I am unable to locate my model on the miele website.

How do you fix hose, there are no replacements for them unless I am willing to pay £170 in UK

Great post

I have a similar one to these - and if you can fix it - well fix it because you are going to find it difficult to buy a better vacuum. There things are made to lasta lifetime - but do need some TLC occasionally. This vacuum is the Mercedes of cleaners compared to the others.

Hello Mr. Performance Review! I bought a Miele Cat & Dog vacuum second hand. It’s upright swivel type. It Looks to be in overall perfect condition but the bottom isn’t suctioning- in fact it seems to be pushing air out instead. The hose is suctioning Very Well (like wow it’s so powerful!!). It has an empty bag, nothing appears stuck around the roller, filters look good, behind filters looks very clean, i can’t find any blockages based on other KZfaq’s, but I don’t know what else to do now. Today is my last day to return it for store credit.. any tips you could share? Or someone you recommend in Phoenix AZ? From your experience is this fixable/worth trying? Sincerely- girl on a budget, Kristin

forgot, what a great video, thx alot

How do I install the Miele U1 button wand repair kit 3595181?

I would love to see a sharp twin energy bagged vacuum cleaner repair involving servicing the motor.

Great video!! Our brush motor is turning off momentarily while vacuuming. I think maybe a bad connection or switch, what do you think? Closest service is 150 miles away in a direction we seldom travel. Any help would be appreciated. Glad to donate in return for help ideas.

I'm in Denver and I need to get my Miele serviced. Do you have a suggestion for a good shop to take it to?

You know you have a sick vacuum when it requires a CAT scan

Good video but why play music when the tech is doing the hardest job- aligning and timing of wheels with upper bag assembly?? Also the camera work could have been better but thank you doing this video. Overall it is very good

Hi ,Top job. Have the same machine. The on-off switch has recessed, and the machine sometimes switches off and on when the body twists. Any ideas, please?

the locking clip on my telescoping wand for this machine fell off and I can't for the life of me figure out how to re-attach. Any clue?

This is a great video tor my favorite vac. Only wish someone could show me how to clean the interior of light lens. 🤔

How do you disassemble the hose so that I can replace the flex part

I have a Miele S7510 and I'm based in the UK. The cleaner is generally working fine but has recently developed a niggling problem. It locks upright OK but still swivels freely from side to side in the upright position, making it difficult to use the hose with various tools. I dismantled it based on your excellent video but couldn't see what would stop it from swivelling apart from a round very slight protuberance on the base and a corresponding hole in the upper part. Does this wear after 6+ years of regular use and, if so, can you suggest any way to raise the profile of the protuberance or the hole?

we have 4 of these, but one we just bought used, the hose has stretched. any suggestions other that buying a new one, kinda expensive i assume, thx

Thanks. I just cleaned the brush roller and put it back together but know it doesn't work.

Help! I'm wondering where you are located and about how much it cost to ship a vacuum for service? My local dealer is ridiculously slow and horrible at finding problems even when I tell them exactly what's happening. They have fixed once before a problem with the pedal somehow some sort of switch inside that makes the roller brush not spin Even though it is in proper position and turned on. With your excellent disassembly video I would attempt to fix it myself except for I'm not sure what part I'm looking to replace. Have you heard of this problem and could you point me in the right direction?

Eversince I used a dry powder carpet cleaning poduct my vacuum has been making a very annoying high pitched noise when using the rotor bar. I assume the powder got into that mechanism when I vacuumed it up. Now, several months later I have no suction at all. Motor sounds fine, but rotor bar spins for a second or two, then stops and no suction. Does this sound like something that can be fixed? By myself? By a pro?

Is it possible to purchase replacement covers, and a new bumper strip for the U1 series?

Hello, My wand from my Miele S7 is bent thanks to my kids. What would the replacement part be for this?

Is it possible to take the brush roll out without messing up the wedge or belt assembly?

It’s such a shame these got discontinued. I just picked up a used one from my local dealer for a great price and it performs well, but there’s a nasty smell coming from it when I vacuum. It almost smells yeast-y? It’s not coming from the bag or filters. Are there any measures I can take without tearing it down to this extent and risk messing something up?

Do they all come with a bag dock?

I’m curious what the air path is like on this machine. Does all dust and debris go through the hose or are there two separate air paths; one for the hose and one for the Brushroll? If everything goes through the hose, then the air path is about as long for this machine as it would be on a canister, correct? I always thought one of the benefits of an upright is the more direct air path. Am I wrong?

I lost a spring, and I can't find a replacement. Any ideas? Thanks.

Is there any way I can repair the hose to it?

My roller brush bar wont work even after taking off the bottom plate and cleaning out significant junk

A friend has one of these & somehow it’s stuck in the lying down position won’t straighten up to be upright something is stopping it , any ideas how to fix it ?

The carpet cleaning function on my vacuum is not spinning anymore. Do you have any ideas to as why??

I watched video several times, hoping to see a fuse or anything that dealt with the motor. My s7850 abruptly stopped and displayed the red light triangle. Let is sit for over a day, start up is immediate red light. So obstruction to overheating is tabled for now. Any insight other than take it to a dealer would be appreciated. Thanks.

Is $200 too much for a new motor? A vacuum repair shop has my U1 and that’s the price they quoted me bc the motor was “shot”. It’s my fault though. I bought it used on eBay and only turned it on to make sure it worked before putting away in the garage bc I still had bags left for my Hoover vac. Once I decide to start using it, I notice that it is not picking anything up. I take it in to get a free estimate. Unfortunately, I’m way past my eBay protection time frame. Would it be best to let the repair shop handle it? I feel confident in being able to replace the motor if it’ll save me more than $80.

Please what is the smaller screw driver???

How do you access the on/off switch to replace it?

The piece from the base.

Tremendous amount of good info. Too bad you didn't make sure many crucial steps were not in the frame as you completed the task! You know how to do it, but we don't and that's too bad for us I guess. Thanks anyway.

Shame at the wheels part the important aspect is off camera. Anybody know the trick?

I can take my Miele S7 fully apart

at the 11 minute mark I can't tell what screws you are removing.

So disappointed in ours. It’s constantly clogging and we’ve had to take it in for repairs twice.

Really really poor camera work. Especially during the re-insertion of the wheels. 10 seconds of decent video and explanation on how the gearing positions actually work in stead of countless comments about "if you don't understand how this works".... well, you NEVER explained it. So how the h-ll are we sup[posed to know?

Please make sure your hands are out of the way so we can see what screw or hole you are talking about.

Watching this to learn how to reinstall the wheels... WHAT THE HELL is with the two minutes of music over you telling us how to reinstall the wheels?!?!

Who wants to get an upright vacuum cleaner.. It looks like it's inferior in every way.

dude move your mic and get your self an inhaler . sounds like your lungs are damaged sorry but very noticeable
