How to Identify and Fix Common Vacuum Problems ?

Our sources include academic articles, blog posts, and personal essays from experienced Vacuum Technicians :

Should the brush not rotate freely there may be debris tangled around the ends of the brush, carefully remove any obstructions or replace the brush with a new one. We recommend that you fit a new belt and brush once per year to keep your Reactive vacuum working efficiently.
This usually occurs if the dust cannister is too full or the filters are clogged and the motor wasn`t getting enough cooling air passing over it.
The brush roll or its bearings may be clogged with hair, threads or dirt. Make sure they are clean and the roll spins. The belt may also have slipped because it was loose. Check the fit of the new belt when it is installed.
Load is too small or unbalanced

For maximum performance, It is important that the load is evenly balanced inside the drum before the machine starts the spin section of the cycle. This will prevent the machine from excessive vibration and movement.

You may have stalled the brush motor. To reset, turn off and unplug, then plug back in and turn on. The brush roll may have lodged debris or other entanglements keeping the brush from rotating. To fix, you`ll need to remove the brush roll to inspect.

I was vacuuming my room and all of a sudden I hear this loud noise, then notice the roller brush isn’t spinning. Thinking too much hair was caught I separated it from the rod and hose to clean it out, but noticed that the roller brush didn’t move at all while I was cleaning it. I’ve cleaned the brush before and it would roll around with little effort, but this time I couldn’t move it at all. After removing hair and string I put the vacuum back together and started it up, but the noise continued,
ANSWER : It sounds like if the rod is clean then there is debree inside the roller where the rod fits in too.

HI, My Dyson DC07 Is excellent When I use the hose, But it’s not so good on carpets. There is no blockage in the bottom hose & all the filters are clean. Also the belt & roller are working & clean Can anybody help?.
ANSWER : There’s a possibility the bristles on the brush are worn down so much they no longer make good contact with the carpet, hence they don’t brush certain types of debris into the airflow of the powerhead.
.You can check the brushes by gently stroking the palm of your hand along the brush area to see if the bristles make good contact. A visual check can also be made by looking at one side of the powerhead, line it up so you can see the other side. If the bristles can’t be seen, the brush needs replaced.

Bissell Pro-Heat 7901-1 no cleaning solution is pumped out. The flow indicator is spinning and the belt is spinning the beater bar. Have cleaned the flow indicator, checked vavles in the solution tank and water tank and they are working properly. Also checked the trigger to make sure it works okay. Any ideas?? Moody Fan
ANSWER : Bissell Pro Heat shampooer – Fill the soap dispenser with extremely hot water and shampoo with only water for a few minutes. There is often dried soap in the lines. Make sure that all filters are clean. Press the soap container and the water container firmly into place so that there is a good seal.
.My repairman told me that after you finish shampooing your rugs be sure to fill the soap dispenser with very, very hot water and go over your rug until the water runs clean (not bubbly). This ensures that all the tubes are clear of clean and there is no remaining soap. He said that this is the reason for the vast majority of his repairs. My machine is about 10 years old and has been working great as long as I remember to run it with clear water when I’m done.

Agitator stopped rotating, has checked for clogs, cleaned agitator, and pushed reset button, but still not rotating. Any ideas?
ANSWER : Try changing the belt

Eureka lightforce 300 poor suction, power paw doesn’t spin and self cleaning duster doesn’t clean its self when the button is depressed.
ANSWER : When this happens to me I do two things. The first is to empty the cannister but when you do (with the vacuum unplugged) stick your hand up inside of where the cannister goes.Sometimes that is filled with debris. Pull as much as you can out. There is another part inside there that you can twist and pull out – this will help you pull out more of the trapped debris. Replace that part and the cannister – usually there’s a blockage and just removing some of that debris will cause a bunch more to dump in to the cannister. You may have to repeat this process two or 3 times untill no more debris comes out when you turn the vacuum back on.

The second tip solution is to clean the filter which can be found on the front of the vacuum.There’s a clear plastic cover, a black rectangular this that hold the filter sponge and inside of that, the filter sponge. I just rinse the little sponge inside and shake off the thing that holds the sponge (Sorry, don’t know the technical terms). Put it back together and you should have suction – viola.

Hope this helps.

Roomba keeps saying clean brushes yet are clean!
ANSWER : Make sure you take off the little cap at the end (the one that spins — just grab it and pull it straight off) and clean under it too. The rest of the brush may look perfectly clean but what happens is that hair gets stuck under spinning cap and, like a slowly growing washer, it pushes the whole brush toward the gear box. When it gets pushed over enough, the large yellow ring starts to rub against the side of the brush deck making it harder for the motor to turn the brush and you get that “remove and clean brushes” message.

Agitator unit on Kenmore Progressive 116.25915503 won’t spin. I have cleaned out all hair and string wrapped around it. Belt is good. It seems to spin on one side but stuck on the other. Could string be caught somewhere?
ANSWER : Pry the end caps off the brush bar, you will find hair and string wrapped up tight in the end. the bearing may also be shot, you can try and oil it up a bit to keep it spinning...<!– from fixya rte –>

I have a Eureka 5902AVZ and the brushroll does not work. when i remove the belt, which is not torn nor worn out, the motor spins perfectly fine. Though when i put the brushroll back into place, it shows that the motor is trying to spin, but with resistance. it seems the brushroll will not spin if locked into place, because there is no attachment on the left side of the brushroll that will allow it to spin freely with the belt. am I missing some parts or is there something else wrong?
ANSWER : Hi and welcome to Fixya. I am Kelly.
.
.You have correctly identified the problem as the brush roll itself.
.
.There is a bearing under each end cap of the brush roll. You can gain access to the bearings usually by gripping the browah roll end caps and rotate the caps in opposing but loosening (ccw rt / cw left) directions.
.
.Many times I have found that there is just a mass of hair under the end cap that functions like a brake. Clean it up really well on under BOTH end caps.
.
.Do a spin test by putting the end caps back on (Hold it horizontal) and rotating the brush roll with your thumbs. It should spin freely.
.
.If it feels like there is still friction then your probably going to have to take the brush roll with you down to the nearest vacuum cleaner repair / supply shop and get 2 new bearings. Most shops will install the NEW bearings for you if you have the brush roll in hand. It is a much cheaper fix than the brush roll itself.
.
.(buy a new belt too!)

. Take care
