Question about Dyson DC17 Animal Bagless Upright Cyclonic Vacuum

Dc17 -too much pet hair around the belt gears

I have had my dc17 for 8 months from Best Buy. It has been in the shop for 2 months cuz of loud noise (sounds like a jet). They have replaced the beeter bar assembly and motor. Got it home after the 2nd repair and the beater bar stops and goes. The repairman now says the gear assembly has too much pet hair around it. I have talked to Dyson directly and they say go to a DC14 which has an enclosed belt and gear assembly. But all the reports I read on the 17 is how people with lots more dogs then my Golden Retriever have had no problems such as this. They say I can continue to use the 17 but will have to clean the gears each time after I vacuum. Any advise? We have a lot of long haired dogs, which is why I bought the Animal DC17. After using it just a few times it started making a TERRIBLE clattering noise. I called Dyson and they said to take it to the repair shop. When I picked it up, the guy said that it just needed the dog hair cleaned from the belt driver. I asked him if there was any way to keep the hair from getting in there and he said there was not. The problem has only gotten worse. It starts making the noise every time I use it, SEVERAL times!!! I remove the beater brush and clean the hair from the belt driver, but after just a few minutes it starts making the noise again. The beater brush seems to be rotating just fine, just makes a terrible racket.

I called Dyson again. They said to take it back to the repair shop. Unfortunately, the close one I took it to last time has gone out of business and the next closest one is over an hour drive from my house.

This vacuum is proving to be a huge PAIN!!!

    I agree, the non enclosed area around the belt causes alot of problems. Seems to be an design problem from the start. You would think that this model (pet model) would need a protected belt area. I have started cleaning the area quite often and it makes a huge mess.

  • jayh30 Aug 12, 2008

    Yep -- same problem here. Ours started doing this after 10 minutes of use. We have a golden retriever. Fortunately, we're within our first 30 days of buying, so we'll be taking this one back. We have a Kirby that is in good condition -- the thing I LOVE about the Dyson is that it has SOOO much more sucking power than the Kirby and doesn't use bags. With our dog, we literally fill up a Kirby bag each time we vacuum the first floor of our house. Anyways, I agree -- this is a design flaw in the DC17. I still like the brand, but I'll be returning this for a model that has an enclosed belt.

    I have had the same problem with my DC17. I have taken mine to the shop 3 or so times, first for a new beater brush and belt, then for a new part they created. The new part worked for about two months but then made it worse because now I can't take the belt off by myself to clean the hair around the gear. I love the sucking power of this vacuum but hate it otherwise. I am trying to find a recommended replacement.

    DC17 Animal appears to be well marketed to us folks with long haired
    dogs. Trouble is, the folks n Product Development either do not own
    dogs, or did not sign off on the promises made by the marketing

    Who knows of a vacuum cleaner that performs as advertised? This was
    $500 down the drain. We spend more time taking the damn thing apart to
    clean it than we do using it. Horrible product.

  • Anonymous Dec 21, 2008

    I have had the same problem with my vacuum. The brush makes the same noise after only a few minutes of use. We have a long haired Saint Bernard and only have a small portion of our house carpeted, but have to clean the chamber twice maybe three times every time we vacuum. We have recently tried to replace he filters and bottom plate in hopes of making the belt housing more secure, but it doesn't seem to work. I think that it is a joke that a vacuum that advertises itself as a vacuum for pets for a mere $500, can't handle pet hair. We will not buy another one.

  • Virginia Bil Feb 10, 2009

    I had the same problem as others here but fortunately, the solution posted by PRODUCEHAWK solved my problem too.

    The tension sleeve bearing on mine was not loose inside the vacuum, but jammed VERY tightly in one of the plastic slots near the belt. It was difficult to get loose, and as PRODUCEHAWK said, a PITB to reinstall but that solved my problem.

    Thanks again PH!

    trouble with dog hair? may be a COMBINATION of many things. another post had this "The Flange in question is about one inch tall and approx 4 inches
    circular ..... When you pull the canister (container to empty) off and
    empty the contents in the trash .... some of us tap it to get the
    excess out or off the sides ..... That Flange is the rubber piece
    attached to the bottom of the darker gray cylinder inside the canister
    you are emptying. When you tap the canister or after dumping it
    numerous times that flange can work itself (slide) up the darker gray
    cylinder ...... it needs to be slid downward and overlap the bottom
    when you close the canister after dumping it. You can remove the flange
    and see the grooves .... place it back on with it hanging off a
    little to allow for overlap(keeps filter from clogging). That should decrease the amount of excess
    being trapped in the filter. Hope this helps."
    so what I found on mine? the rubber flange was out of place. this caused the filter to clog prematurely. clogged filter produced little suction and that in turn caused hair build up on brush and motor gear. where else would the hair go with no suction? so check that flange, maybe get a clean filter and the hair should get sucked up rather than wrapped around the brush. still waiting for results of my own. 1 good cleaning and still not bad. hair not an issue (yet).

    We also have a long haired dog. And I can't even vacuum half our living room without the belt getting clogged up. I called Dyson about it and they never even suggested any kind of tension bearing, just basically said, yeah, that happens, you need to clean it out every time.

    They probably tried to get rid of me so they don't have to pay for more warranty work for a known problem.

    How do you get to the gears?

  • Anonymous Mar 24, 2014

    My beater bar on my dyson ball makes a lot of super loud noise especially when I'm vacuuming hardwood surfaces. It also seems like the brown tip of the beater bar is broken because it sticks out from the front. Do I need to take it to a repair shop or is this something that I can order parts for and replace myself?

I was having the same trouble and it was driving me nuts.  I tried cleaning and it did not work.  Then I tore the brush assembly off and looked up into where the little tooth gear is.  I saw something that did not look right.  There was a silver roller bearing laying down below the assembly.  I got some tweezers and found it was not attached to any thing.  I then cleaned out the pet hair and saw a spot where this roller goes that takes the slack out of the brush. It is a pain and takes alot of trying with pliers and prodding  with a screw driver, but I got the roller back where it goes.  It does not attach very solidly, but I put every thing back together and it works great so far.  It is a definite design flaw.  I found that you have to keep the main unit on  the floor when the brush is running.  Do not do stairs or pick it up and do couch cushions, that is when the bearing breaks loose.  Dyson needs to figure out a better design for this.  I was lucky to figure it out, but it is very hard to get to.  Again never pick up the unit when the brushes are engaged.

Honestly, I have taken to "cleaning" the clearner EVERY SINGLE TIME, after using the system (about a 30 minute cycle time). You simply must remove all hair from the hoses. Then it works fine.

    If your Dyson DC17 vacuum has a belt tensioner (small bearing that rides on the belt) you need to replace the motor cover and belt, this will reduce a lot of head aces. Older model DC17s used the belt tesioner but Dyson realized the flaw and now recommends replacing the motor cover (which does not include the belt tensioner) and the belt, which is smaller.

    I found the parts for this easy repair here

    I also purchased the repair kit which includes the new belt

If it makes noise everytime you use it it has probably stripped off 3 or 4 of the rubber cog teeth on the belt and needs replaced.  Oursdid this when we accidentally ran the sweeper over a towel.

I've been dealing with the Dyson issue for two years now. I have two of the same unit. Dyson sucks when it's on AND when it's OFF! I've replace tons of belts and bars AND a motor. They wouldn't replace it under warranty because the company said I "abused" it. I have St. Bernards too. The damn ridged part on the shaft of the roller motor is ALUMINUM!! It is bare threaded now and so the belt just spins on it without "engaging". It's done that on BOTH vacuums and I'm currently trying to find a REAL metal one to replace the crappy ones. I may have to have them made since my brother is a machinist. And my sister has the same vacuum and NO INSIDE PETS. I just cleaned out a glob of stuff wrapped around the shaft and in that whole area. WHAT POOR DESIGN!!! I have to blow out the whole bottom and the "cyclone" thing constantly with my dog blower. I think I liked my Electrolux WITH BAGS better than these poorly designed Dyson vacuums. BTW, get filters, bars, and belts ALOT cheaper on eBay. I'm tired of getting screwed by the vacuum repair place that's constantly trying to sell me a Sanitaire (because he's a dealer). He's the **** that told Dyson I "abused" the vacuums. What a joke! Hope this helps other suckers that bought this piece of poo.

I have the DC17 Animal and had the problem with hair clogging up the belt area also. I can clean it out with tweezers or whatever but it's a pain. When I called Dyson, they sent me a new beater bar with a wider belt and said it should take care of the problem. However, there are no instructions with it so I have no idea how to replace the beater bar and belt with this new one. Is there somewhere I can get a service manual or instructions for how to do this?

    Aelanna, did the new install work? If so, can you please provide the model numbers of the new beater bar and belt? If not, that's fine but I'm trying to deal with the same problem. Thanks

  • Aelanna Dec 29, 2015

    I never did get it installed, since I couldn't find any instructions and didn't want to attempt to disassemble my vacuum. I've been working with it as is. I still have the parts, but as I'm packing to move don't have access to them right now to give you the numbers.


I had the same problem...the vacuum making a loud racket and the brush was difficult to turn even manually. Just clean out belt gears, FRONT and BACK. The silver rod on which the belt sits on tends to collect hair and get clogged up. It'll seem like something is wrong with the belt as if some of the teeth are missing but it is just the hair coming in between the belt and rod. Hope this helps. Mine doesn't make the noise anymore. Dyson may tell you to take it to the service station to see if the belt broke or something else...try this yourself and save your time.

Go to a DC14 there is a reason why Dyson calls it the Animal. It's ment for all the pet hair and things like that, listen to what Dyson recommends you, they know their products well.

When I go to vsacuum carpets I have a loud squalling sound. I replaced belt and still have noise, very loud

Does it make the squeeling noise if you run it without the brushroll or belt installed ? That would indicate a bad motor bearing. Try that, then take it to your local vac shop for help.

Why is my central vac. making such a loud noise. It sounds like jet getting ready for take off. It seems to be getting louder. I'm not using it because i'm afraid it's going to explode or...

The bearing or the motor is warn out they last 15 years in the case. In some rare case the brush ware out or the rely can catch fire, most central vacuum are not made to be oiled! Hot oil will catch on fire. Best to unplug the vacuum unit call a few shops and ask replacement motor cost, if you remove the Vac and take to them it will cost less.

Very loud "jet like" noise,please


Vacuums are noisy, but shouldn't sound like a jet.....

Trying to find out what is wrong depends on what kind of noise it makes, i.e. high squeal, vibration, whining and where it comes from.

Here is a webpage with troubleshooting advice on noise in vacuum cleaners. Hopefully you should be able to track down the problem.

If you need further help with repairs, please reply back. Thanks,

Making a loud jet engine sound

We had this problem also, the easy fix for us was taking out the soil container, then reach in and grab the gray cylinder and twist left to unlock it. pull it out, sometimes pet hair clogs the ports that make the cyclone action. Once you clean it out, put it back in and twist to lock position. There is a little lock/unlock indicator on that gray cylinder. Hope this helps, it fixed our "jet engine."

The beater bar makes a horrible clunking noise when I turn it on

I just came from the repair shop. There is a recurring problem with a bearing coming out. Repair guy turned it on & said that loud noise is a symptom of that exact problem. This is a warranty item, as is the belt & on/off switch. Dyson comes with a 5 year warranty, so call their 800 number to get the name & address of an authorized repair shop.

My Electrolux is about 3 years old. Never had any problems with it until recently, it is LOUD. It doesn't seem to make a 'normal' running noise unless it butts up against a wall, furniture, etc. trying to vacuum is like being on a jet runway. Is something clogged? Does it just have issues from not being used for about a year? (Last house had no carpet).

I would advise you to ALWAYS to FIRST UNPLUG YOUR VACUUM before beginning any service procedure.
It sounds to me that you have a broken fan, in every vacuum I have seen with the loud noise such as you described, it has been a broken fan or fan blade and is in need of replacement. You can try to do it yourself but I suggest going to your local vacuum cleaner dealer for service with the problem. Remember, a suggested belt change if the belt is flat would be 4 to 6 months and If you have a geared belt the belt change would be one year or better depending on wear factor. So, if you need further assistance, please feel free to contact your local vacuum cleaner dealer in your area or in the yellow pages, or contact the factory phone number or website to further assist you with your questions.
