Why is the roller brush spinning half heartedly and making a hesitant whining noise. It's not really picking up anything.

what does the really loud noise sound like? Is it a loud, whining sound? if so, the motor may be getting ready to go out. Also check that the belt isn't stuck-though you would smell burning rubber if that were the case.

What kind of Hoover is this? There are a few things that will cause excessive noise and vibration such as a worn belt, the wrong belt, damaged end caps, damaged brush roll housing and worn bearings. Inspect the brush roll area. Remove the belt, if you have a spare, check the size. If it's more than 6 months old, replace the belt. Spin the brush roll in the housing, does it spin free or hesitate or not turn at all? If it spins with effort there could be debris under the end caps; if one end cap will not turn there is enough debris to cause the end cap to internally melt to the roller. If you cannot turn the brush roll by hand, replacement is your best solution. You should also inspect the housing where the roller spins, specifically where the end caps sit; look for damage to the slots in the plastic, it the roller will not sit snug this could cause enough vibration to make the sound you're hearing.

It sounds like if the rod is clean then there is debree inside the roller where the rod fits in too.

Trace the path of the suction into the tank and see if there is anything loose or ingested. Also, remove the brush and clean as best you can. Perhaps there is something caught in it. Lubricate where it makes sense with some WD40.

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 :)

Hello,

When a Dyson DC07 makes this horrible grinding noise, it can only mean one of three things.

The Dyson DC07 uprights use a clutch mechanism to control the brush spinning when you change the floor / carpet switch. When you hear this grinding noise, it's actually the clutch slipping because it can not spin the roller brush. Most other uprights use a belt to spin the roller brush, and if something is stuck in the roller brush it will cause the belt to break. Dyson's however will make that awful grinding noise rather then breaking the belt, and will only make that noise if the roller brush can not spin.

When you hear this noise on a Dyson, it can only be 1 of 3 things. Either your clutch mechanism itself has gone bad, or the roller brush itself was not properly put back into the vacuum, or the brush itself has gone bad.

I'll be happy to walk you through step by step on how to diagnosis this problem and find out which one of these two parts is bad on your vacuum.

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 completely, 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 maneuvering, 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 roller brush went bad, then you'll need to purchase a new one. Here's a direct link to the roller brush your machine uses on our website GoVacuum:

If the brush however was able to spin freely, and it spun multiple times, this indicates that most likely the brush was not put back in properly, or it could be a little more serious of problem in the clutch itself has gone bad. The clutch replacement repair is a much longer, more challenging repair to do. There is a very helpful 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 think more likely however it's probably that the brush was not put back in properly, and this caused the brushes not to be able to spin, which would cause the clutch to make that horrible noise. Make sure that the roller brush is pictured like the brush above, you may also want to make sure that the bottom plate is put on correctly, this could also prevent the brush from spinning:

Here's a picture of the WRONG way to install the bottom plate. Notice the gap in between the two housings:



Here's another picture, that is the RIGHT way to install the soleplate:

When you hear that grinding noise, it can only be one of these three problems. This clutch mechanism was so problematic that Dyson removed it on the second series of the DC07 models.

Greetings,

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 roller brush went bad, then you'll need to purchase Genuine Dyson DC-07 Roller Brush for Models That Use a Clutch Part # 904174, then reinstall the new roller brush into the vacuum when you get it.

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.

Is there any thing caught in the roller brush? Carpet string, plant leaf,Coin?

Try removing the suction hose and putting a broomstick through it to unclog any thing you may not be able to see.

At the area where the roller brush is look at the suction hole, feel with your finger if anything may be caught inside.

If all is clear you may have a defective motor.Return it while you still can.

Thanks and good luck.

Your roller brush is starting to fail. If you unscrew the ends, you will find a lot of hair wound around the stem. You probably have a warped plastic end the holds the bearing. This is my problem now.... I am looking for a new roller brush as I write this. I found one for $30. Good Luck.
