Question about Hoover 5416-900 WindTunnel Bagged Upright Vacuum

1 Answer

No suction at floor brush. Plenty of suction in the tube that goes to the joint just before the 90 degree turn to go from the handle to the brush area.I lowered the handle so that the tube was straight and probed. The tub is clear. I cann't find the manual at home or on line. The site is useless in searching for a manual.

Are you sure the brush roll is turning. If not sometimes it will appear to not be sucking. Take off the bottom plate, then you can get to the brush roll and belt.

Has suction when handle is in up position. Not suction when bring the handle down.

Is this a Dyson?

when the handle is up, suction is diverted to the handle for the tools and you can hear it sucking at the top of the handle. When you lower it, the suction goes to the floor head. If you have no suction at the head when you do carpet or hard floor, turn it over, turn the three screws a quarter turn using a 25 cent quarter and remove the bottom plate. Clear any obstruction.

Where do you put attachments to make them work?

There is a button on the handle that releases the suction tube from the floor brush housing. Once the suction tube is released from the brush assembly, you can install the attachments on the suction tube.

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


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:

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:

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. ....

When vacuuming carpet with the electric power brush it will ocassionly , go to zero suction mode and shut off the brush. I have tried to cause it to happen by playing with the joint areas ( handle to tube...

You gave a good start to giving us good information to help you with solving this problem-- But I need a little more information:

It sounds like you have the Electric Motor driven Power nozzle/ Floor attachment-- am I correct? (Not the type that has a little vacuum motor down at the floor attachment-- Not one that depends upon air flowing thru the unit to power the brush, -- am I correct?)

You can control the motor with a switch at the handle-- correct?

So here is the question: - when you say "the electric power brush -- goes to zero suction" -- what tells you that it 'went to zero suction'?-- the little red flag on the vacuum?-- or what?

I am suspecting something might be caught up in the floor wand-- or at the power nozzle itself-- or even in the flexible hose. Do you know how to take the hose off, and place the hand-held end, in the opening in the Miele Vacuum? Can you do that, and clear out the hose first-- and then the hose with the want connected?

If they are all clear-- we may need to open the floor plate on the floor nozzle, and check for something caught in the air passageway--

No suction

Check the tube that leads down to the brush head for clogging as well as any motor or HEPA filters. If that still shows nothing, take the cover off the brush head (like you're changing the belt) and look for obstructions in there. Usually, if you have low suction on the accessory hose, the problem is with a motor filter, HEPA filter, or a clog where the hose goes into the unit. If you have good suction on the accessory hose but none on the floor, it's usually in the brush head (clog or broken belt) Good luck

When I turn on mt dyson is sounds normal. once I

With the DC14 in its upright position, and looking from the back, there is an access hatch just to the right and bottom of the dust canister. Remove this and check for any obstruction. With the hatch still removed, tilt the handle back (as if vacuuming a floor), and you should spot that the mechanism in to which the access hatch fits changes over from one hole to another. This is how suction is transfreered from the telescopic arm to the brush bar when the unit is taken out of the upright position.
With the handle tilted back, the hole you can see is one end of a flexible pipe that leads to the brush bar. Check for any blockage and/or foriegn objects. If there is no obvious problem, you'll need to check the other end of the pipe. You can do this by removing the toe plate on the bottom of the brush bar area. The plate is held by 3 or 4 half turn fasterners - a 5 pence piece is ideal for undoing these.

If still no joy, the only other thing it might be is that the brush bar isnt spinning - this isnt actually lack of suction, but without brush rotation any upright hoover is far less effieicnt at picking up bits from the floor. Brushes not spinning on a DC14 is quiet a difficult thing to fix on a DC14 as there are two separate rubber belts, one of which is hidden under a plastic cover. There is also a clutch mechanism between the belts that can cause problems some times.

Suction loss when handle is tipped back to clean carpet

can any one help,
Our Dyson Animal vacuum has plenty of suction when it is upright and the attachments are being used off the hose, but when the handle is tipped back to begin cleaning carpets the beater head is getting no suction. As the handle is being tipped back you can hear what sounds like a flapper valve in the body of the vacuum opening and then all the suction just goes away.

No suction when vacuming floors


There are 2 types of Dc07 one is clutched & has two belts the second has only one belt going from motor to brush roller.

Lay machine on its side pull back handle as if you are to vac carpet switch machine on look to see if brush roller is spinning.

If it is not spinning unplug machine from mains supply & remove the sole plate by turning the three plastic screws to unlock position, Lift sole plate away if you have non clutched machine you will now see the brush roller with A belt going from this to the motor shaft belt may have snapped or come off so replace it.

If your Dyson has A clutch unit this engages the brush roller when you pull the handle back to vacuum.

Check the clutch control knob which is at the bottom left side of machine looking from the front.
It should rotate to drive position when handle is pulled back.

If it doesnt turn the knob by hand to drive.

If you still have no brush rotation after doing all this then either the clutch is faulty or the second belt which goes clutch to motor has snapped & will need replacing.

There are service manuals available for these repairs at this site
