First came the burning smell then a chunky grinding noise and finally little black pieces. I spend more time cleaning out this vax than using it.Hair around roller brush starts burning and the top of the canister gets matted with fine particles. Maybe this unit is too good at sucking.
Not too good, but there are motor problems with these models all the time. Personally I do not know it can be fixed without replacing 3/4 of the machine, which can be pricier than a new higher quality sweeper. I work for a repair shop/ dealer so if you need some assistance let me know.(570)326-1731

Your problem is caused by hair,strings,etc getting around the beater bar at the ends of the roller where the bearings are and causes it to sease up.
The smell you smelled was rubber burning, the rubber belt that operates the roller brush has burned into...broken.
You will have to remove your roller brush and clean, and oil and then reinstall it with a new belt
Please take time to rate me
Is the brush/roller spinning? If not, then the connection between the roller is broken, it is a two piece roller connected by a round black piece. there is a gear under there that can break and keep the roller from spinning together.
Hi there SmartAlec from NelsonVacuums.com.au here. The rattle is the clutch engaging. It can happen for a couple of reasons. The best case for you is if there is something caught in the brush roller that you can simply remove. The next best is that the end caps of the brush are full of junk that you will be able to remove. Its not easy getting the brush out to clean there but it can be done. If the brush spins in your hand easily when the brush is removed then it is the clutch itself. THe main roller often melts which is caused when the tension on the belt gets to high thus creating too much heat. THis can be resolved only with a new clutch. Hope this helps, if you have more questions dont hesitate to reply or if you need parts just visit NelsonVacuums.com.au. Happy Vacuuming :)
When the Dyson DC07 makes that horrible grinding noise, there's really only one of two things that can be wrong. I have taken a few pictures to help you try and diagnosis the problem.
The grinding noise is made by the machines clutch mechanism. The clutch is what stops the roller brush from spinning when you change the vacuum from carpets to bare floors. The grinding noise is the clutch slipping, and not being to able to turn the belt. In most vacuums when the belt can not spin freely it will cause the belt to burn or to break. On Dyson's, the clutch mechanism prevents the belt from burning or breaking if you were to get something stuck in the brushes such as a towel underneath of a bad, or tassles on an oriental rug.
So when you hear this grinding noise, only two parts could be bad, the actual clutch mechanism itself, or the roller brush. I'll gladly help you diagnosis, and give you instructions on how to fix your Dyson.
Step 1. Make sure the vacuum is unplugged. Then turn the vacuum upside down so that the brushes are facing up. It's easiest if you put the head of the vacuum on top of a bench, or counter top. This is how the vacuum should look:
Step 2. You see on the bottom of the vacuum 3 plastic screws that are usually the same color as the vacuum cleaner. If you're vacuum is purple, the screws will also be purple. Use a flat head screwdriver, and turn each of the 3 screws a half of a turn, counter clockwise to loosen then. After each screw has been turned (you don't need to remove the comletely, just a half of a turn is all), simply pull upwards on the bottom plate to remove it.
Step 3. You should now be able to see the roller brush exposed. You'll now need to remove the roller brush. This will take some patience, and some work in order to get this brush out of the vacuum. There is a special tool that has been designed to help you get the brush out easier. I would try getting the brush out first before buying this special tool. The easiest way is to use a flat head screw driver and pry the belt up while pulling up and out on the brush. With some patience and some manuvering, you'll be able to get the brush out of the vacuum. Here's where you should put the flat head screw driver on the brush:
Step 4. Once you get the belt out of the vacuum cleaner, it's time to test it. Use your finger tips to hold just the end caps on the very end of the roller brush. While holding just the end caps, use your thumbs to try and spin the roller brush. Does the brush spin freely? It should rotate completely several times on each spin. If the brush doesn't spin, or you feel some kind of resistance to the brush spinning, then this indicates that your roller brush has gone bad. Here's a picture of how to test the brush:
If the brush however was able to spin freely, and it span multiple times on each spin, this indicates a little more serious problem of the clutch itself has gone bad. The clutch replacement repair is a much longer, more challenging repair to do. I posted a video on how to replace the clutch below so that you may follow step by step instructions on how to change it. It was really helpful for me the first time I did this repair.
I hope that this was able to at least diagnose the problem for you. That horrible grinding noise can only be one of those two problems.

If it is a smell of burning rubber - most likely your vacuum belt is overdue for replacement.
At this point - remove the brush roller, remove the old belt, clean off your brush roller and remove any string or hair that may be bound up around it (usually around where the belt goes or on the sides), and put on a new belt. Your Kirby should act good as new if your bag is replaced at the same time.
If the brush roller has too much string and hair wrapped around it, many times the brush roller will not spin as fast as the belt is driving it and you will get that burning smell.
Your belt is worn and stretched and so it is slipping on the motor drive shaft. That is why it is noisy and smells like burning rubber. You simply need to replace the belt. You can get replacement belts here:
I had the same problem with my DC15. With the brushes going it smelled like burning hair (bad). I had cleaned the brushes many times and it didn't seem to help. I even took it into a Dyson authorized repair shop and they couldn't find anything wrong with it. As a last resort I called Dyson 866-693-9766 1-866-My-Dyson. I was on hold for about 15 minutes before getting a live person. He had my problem diagnosed in literally 1 minute. I had hair wrapped around the spindle, inside the brush/roller mechanism. He walked me through taking apart the brush mechanism (super simple only using a quarter). There was a TON of hair crammed around the spindles and inside the brushes. All wrapped very tightly. I hung up with him to do the cleaning. It took some time and I had to use tweezers to get inside the rollers/brushes. But I got it all, put it back together (which was really easy) and tested it out. No burning hair smell at all. FIXED!
take the belt off again you will see burnt rubber from the old belt stuck to the motor shaft.you can take a fine piece of emery cloth and clean the shaft down to its polished finish.always good to do this after each belt.check the brush roller and see if there are any signsd of plastic melted.make sure it turns freely if not the brush roller might be siezing uo on youhave you cleaned the hepa filter?does it smell like wires burning or rubber.with it unlugged take it apart to the motor and take a fine iece of emery cloth and go over the motor armature .then try it again.you can take all the filters out and run it without the filters.that will help you narrow it down.please leave feedback
I just fixed mine. It took me all of 10 minutes. Pull the brush out. Stand the brush on end on the edge of your study work bench/table top. while holding the brush vertical( on end) take a small phillips screwdriver and tap using a hammer on the metal pin you see in the middle of the brush. Keep tamping and the whole assembly will come apart. What you will have then is a long metal shaft, 2 bearings(they are acutally skateboard wheel bearings same number same make). Clean the gobbed up hair with a razor blade and then reassemble by tapping back together. The bearing wont be worn out because they are way too tough for a vaccum. We used ride down hills on them! a ten minute fix wow and you wont have to drive to vacuum shop and spend $$ and time
