Lay the machine on the floor with the front side down. Undo the 3 large plastic screws with a coin of some sort, then remove bottom panel. On the back of carrage where the roller bar sits their should be a clear plastic tube check this tube is free of dirt. Check around inside the carrage for hair string etc. Check belt for breaks and swelling in the rubber pull ont roller bar and check the end caps on the roller can spin freely. If not pull off the end caps these will be very tight and wash out all dirt and fluff, dry thourley and lubricate centre pin and end caps inside the roller with baby oil or wd-40. replace roller bar and belt, turn roller bar twice slowly to centralise the belt, replace bottom panel making sure that the clips on front are sitting in their holes. fastern the plastic screws and leave two hours before usage

Plenty suction from wand, but when you tilt back to vacum no suction at base but brushes are turning


Hello,

There could be a few things that would cause your Dyson to have no suction. I will give you detailed step by step instructions along with pictures on how you can diagnose this.

Possible Problem #1. The first problem is extremely common. In fact, we probably see between 2-3 of these problems every week. It mostly happens after people take the bottom plate off the vacuum in order to clean the roller brush. What happens is when they reinstall the bottom plate, they put it on on incorrectly. It's actually very easy to do. When the bottom plate (soleplate) is installed wrong, there will be a gap between the bottom plate, and the agitator housing, or the purple tray the roller brush sits in. This will cause the soleplate to be a few inches higher off the ground then it should be, preventing the brushes from even hitting the carpet. This makes it seem to the user that vacuum has lost suction power because without the brushes hitting the carpet, the machine will not pick up very well on floors, but when they use the attachment hose there's plenty of suction power.

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:


8b953d0.jpg
I would say probably 6 times out of 10 this is the problem with the customers machine. If you checked the soleplate and it is installed correctly, move on to the second possible problem.

Possible Problem # 2. Turn the vacuum cleaner upside down so the brush roller is facing upwards. I found the easiest way to work on it is to put it on a counter top or work bench. On the left hand side behind the roller brush you should see a flexible transparent hose that goes from the motor to the agitator housing. This hose actually has a lot of strain on it when the vacuum cleaner is in the reclined position. When the first few series of Dyson DC07 models came out, they didn't make this hose long enough, so when the vacuum was in the reclined position, it would put too much stress on the hose, and cause the hose to actually crack, usually right where the end of the hose that goes into the agitator housing. Examine your hose and see if you have any visible cracks in this hose. If you need to you may just remove the entire hose assembly by pulling on it. It will easily come right out of the machine so you can inspect it better. Here's a picture of where the hose usually cracks:


54cb5e5.jpg
This would also explain why the vacuum works fine when using the attachments, but not on the floors. The attachment hose uses a different suction channel, and when the machine is in the upright position, no suction goes through this hose. If you do find a crack in this hose, the this hose needs to be replaced. Here's a direct link to that hose on our GoVacuum website.

Possible Problem #3. I would suspect that this may not be the problem, but if neither of the solutions above worked, then try this one. Dyson's in general are prone to clogging. There are a few clog ports throughout the vacuum cleaner that were added there due to Dyson prototypes becoming clogged at these points. Here are pictures of how and where to check for these clogs. Simply remove the suction port covers at both of these locations:

Possible Problem #4. If none of the above solutions worked for you, try this last one. The Dyson DC07 models use a clutch mechanism that stops the roller brush from spinning when changed from carpet mode to bare floor mode. This clutch mechanism is a notorious problem with all Dyson models, in fact they were such a problem that Dyson had to redesign the DC07 model to a non-clutch system. Even if yours is one of the newer ones that don't use a clutch, yours still has a belt inside. You can tell if your model uses a clutch or not by the shape of the roller brush. If your brush is a perfect cylinder shape, yours does NOT have a clutch. To check and see if the clutch or the belt have gone bad, first release the handle on the vacuum as if you were vacuuming carpets. Make sure the machine is set to carpet mode. Now while the handle has been released, turn the machine upside down and see if the brushes are spinning. If the brushes are spinning then turn the vacuum right side up and put the brushes on the floor. Can you still hear the brushes spinning when they are hitting the carpet? If yes, then this is not the problem. If the brushes however are NOT spinning, this indicates either your brush roll, clutch, or belt have gone bad. ....

I have a Dyson Telescope vacuum. Everything works fine, except the attachment used for floors. I can feel air and suction going through the attachment, but the brush doesn't rotate or move at all....


If you have suction as you say, the tool is faulty.
They come apart so you can clean them. remove all hair and debris from the roller brush (use a coin to split it using a quarter turn on the two/three screws). Try turning the brush with your fingers. If it is stiff, it needs attention to the bearings in the tool probably. If it turns OK, then the mini turbine inside is faulty -- replace the tool.

Brush does not turn. suction with the handheld unit it fine but when used as a floor sweeper it hardly picks up anything


these stick mmachines do not have a tremendous amout of suction at the best of times but if it has a full bag, or full dirt container, or dirty exhaust fiters it will take away from the air flow as well. take a flashlight and look up in to the tube of the floor attachment to see if you can see something blocking the tube.If there is no obstructions it may have a roller bar that spins on the bottom , so turn it over and turn it on and if it has a roller bar and it is not spinning it probably needs abelt . If there is no roller bar and no blo0ckage chances are it is just weak at the floor tool as the air a further to travel all the way up from the floor so it takes away from the air flow again. good luck.

I got a cord wrapped around the roller, and now neither the roller nor the suction work...only hot air coming out the top of the base.


To unrap the cord from this vacuum you will have to do the following:
First turn the vacuum upside down and place head on counter and handle on the floor. You will have remove the base plate. There are 3 screws that hold it in place. Since cord is wrapped around the brush roller you will not be able to take it all the way off, but it will give you access to the brush roller. If the belt is still on the brush roller, I suggest you cut it, so you can lift the brush roller out of the base and that will make untangeling the cord easy. If you need a new belt here is the info on that.

I have a wind tunnel vacuun and the roller will not turn


There is only one motor which turns the turbine and brush. Therefore, if the suction from the turbine works check the belt by removing the bottom plate of the vacuum and look for the belt attached to the brush roller or if only a piece of the broken belt is inside the unit. If the belt is attached and intact look for a mechanical switch to turn on and off the brush and make sure it is not on bare floor or off. Look on one of the edges of the brush assembly for the clutch which is attached to the mechanical brush switch with a rod. The clutch will close and open when you move the mechanical switch. If you cannot turn the brush unit by hand you may need to remove some objects such as string or hair from wrapped around the clutch or brush.

Check for a blockage between brush and entry into dust chamber, if something has not made it's way to the dust chamber could result in low suction1

Eureka 4870: Brush roller turns even in hose setting.


You either have the wrong size belt, most likely too small, or you have installed a new belt incorrectly. When you open the cover on the bottom of your vac, you will see the pulley that moves as you flip the switch from floors to carpet. The belt does not go around this pulley. When activated(carpet) the pulley puts tension on the belt causing it to turn the roller. When switched back to hard floors, the belt looses tension allowing motor to cause suction but disabling roller. Also, the dial on top of vac is only to direct suction, not for disabling roller

Only suction to attachments


Something is stuck in the throat of the floor head, between the brushes that turn, and where the hose connects at one side (usually right hand side) of the floor head.
