How to Identify and Fix Common Vacuum Problems ?

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

If your machine is making an abnormally loud noise it is likely due to the belt slipping or the brush roll being incorrectly installed, follow these steps to resolve: Turn off and unplug machine. Use a Phllips-head screwdriver to remove 3 screws, 2 in the belt cover and 1 on the brush roll mount. Remove belt cover.
You may be hearing excessive noise because your filters are dirty. To clean them, watch our Cleaning Filters video. A damaged Brush Roll could also be the problem. To fix, first make sure your vacuum is turned OFF and unplugged.
If brush will not turn by hand, or belt is broken, replace the damaged part by ordering online at BISSELL.com. Clean off any debris on the brush. If the brush is still not turning, please take the unit to an Authorized Service Center to have a Quality Technician inspect the unit.
However, the noise levels of vacuum cleaners fall between 75dB to 85dB. Thus, continuous exposure to such noise levels affect a user`s health while also being a sign and source of inefficiencies in the equipment.
The suction power indicator tells you when the air flow in your vacuum is reduced due to dirty filters or a clog in the hose. The suction power indicator will remain green until the airflow is reduced.
Your Vacuum Pump Is Noisy

Sometimes, extra noise can mean that there are pieces of debris stuck in the system rattling around. It can be an easy fix—just locate and remove the debris. A loud pump could also mean you have worn bearings that need to be replaced or lubricated.

Upon the first use of your steam mop or first use after refilling the water tank, the pump may make a knocking sound. This is normal and should diminish after a few seconds. If the sound continues if may be because the metal tube is not reaching the water in the tank.
Grinding noises are often caused by bits of debris getting lodged behind the brushes or into the cleaning head, especially large bits like dry pet food. This will clatter around or jam the brushes to create the noise you`re hearing. A thorough cleaning should put everything right.

Noise My Dyson DC08 is making a loud, rough, vibration/noise that seems to be coming from the from the rotating brush housing. I replaced the old belt which was several years old and slipping. When I run the motor with the new belt removed the machine sounds normal. The bearings on the rotating brush seem to be running smoothly when turned by hand both when out of the brush holder and when installed in the machine. I can’t find anything rubbing on the belt or rotating brush. I applied a bit o

Hoover WindTunnel Self-Propelled V Belt
ANSWER : I had this same problem with the V belt on my Hoover Vaccuum..
.There are three (3) basic things that will cause the brush roll not to spin..
.1. When handle is upright, brush roll is OFF..2. When switch is set for HARD surface, brush roll is OFF..3. Broken/worn FLAT belt or V Belt, brush roll will not spin.
.
.I noticed that the brush roll was not spinning when my vacuum was set for CARPET. After removing the cover I noticed that the V belt was loose, I thought the belt was worn so I purchased a correct replacement belt and installed it, but the new belt was also loose and when I turned the large flat belt pulley it did not turn the V belt pulley at the same time..
.I double checked the surface setting and I had the vacuum switch set for carpet, but still when I released the handle out of the upright position the brush roll would still not spin..
.My aggravation finally led me to this posting on FixYa’s website..
.The first thing I did was checked the screw to the left of the V belt as suggested by ejmjr5 and this did nothing to solve the problem or create more tension on the V belt, even when the upright handle was not in the upright position..
.After playing around with the surface setting control switch/nob I notice that when I moved the switch out of the HARD surface setting and over to CARPET, I had thought that the switch was set for CARPET as it visually appeared, but I was not pushing the switch over hard enough to click it into the CARPET setting mode..
.VOILA, the brush roll now spins correctly even though the V belt seams to be too loose for the pulley..
.You really have to force the switch into the CARPET setting. Be sure that you hear the switch/nob click into place..
.Now you can effectively clean up after that hangover of a party!.
.Burp!

I replaced the belt on my Dirt Devil Featherlite Bagless Vacuum and the brush roller rubs and makes a very loud noise when turned on. I have gone exactly by the manual instructions and made sure the belt and end caps were on correctly, but the bristles still rub the back and it makes a very loud noise. Without the brush roller in the vacuum, it sounds and runs normal. What could the problem be?

.Hello,
.I would advise you to ALWAYS to FIRST UNPLUG YOUR VACUUM before beginning any service procedure.
.The Royal Dirt Devil Featherlite Bagless Vacuum has just bushings in the ends of the brushroll and not bearings and once the bushings are bad I suggest that you replace the brushroll in the vacuum and put a new belt on the vacuum as well. There is no way to repair the bushing s in order to it to work properly. The suggested belt change is every 4 to 6 months and to store the extra belts in a Ziploc bag in the refrigerator to keep them fresh. Suggest looking at a local vac dealer. So if you need further assistance, please feel free to contact your local vacuum cleaner dealer in your area or in the yellow pages, or contact the factory phone number or website to further assist you with your questions.

When I vacuum w/ the brush control in the on position it make a really loud noise, almost like a grinding sound. I have looked at it and nothing seems to be wrong, but I notice that the pin that engages the belt seems to vibrate a bit, possibly creating the noise. It started when I accidentally got part of a plastic grocery bag caught in the brush. Could it have stretched a belt? Nothing is caught any other place and it only makes the noise when the brush in in the on position.
ANSWER : Yes, the belt could have been stretched and is now vibrating and hitting other parts and creating a noise if much of the bag got caught under the belt. If you have another belt for this vacuum, please put it on and see if the noise stops. If it does, then problem solved, if not let me know and we can try something else and you can send a picture or video to me of the problem.

Let me know how this works out for you.

I have a Eureka 4870GZ. It turns on, but the brush roller doesn’t move. The belt looks fine. I do have an extra belt and would try replacing the old belt, but I can’t get the old one off the motor shaft or the new one on. I called Eureka customer service. The lady said there’s supposed to be a small space between the motor shaft and the outside edge of the vacuum where I can slip the old belt off and the new one on. I don’t see it. It looks like the motor shaft goes into a recessed place in the
ANSWER : Remove the top cover so that you can access to belt, You’ll find 2 rows of 4 decorative holes on the top cover, In two of the holes you’ll find the screws, Please use a flash light to see in that., Once the screws are removed, you’ll be able to take out the top cover. Pull the belt so that it should rotate the shaft and look for small space in between from where you can take off the old belt and new belt on. remove the agitator from its drive shaft, put new belt in, put the agitator back into place.

My brush roller stopped spinning so I had to take it off and clean out all the hair that had gotten wound around it. I replaces it and now it is make a lound noise, but only when the brush is on. Could it be the belt making such a loud sound? It wasn’t making this noise before.
ANSWER : Could very well be the belt..When cleaning the brush it is a good idea to add some WD40 at the ends where the plastic pieces are that hold the brush in the vacuum. The brush needs to be able to move freely around the plastic pieces..Add the WD40 and rotate the plastic pieces around the brush until they move freely..Reassemble making sure the belt is put in correctly so the brush moves in the right direction..

Windtunnel belt I have a new Hoover Windtunnel canister. The belt keeps coming off. It happened a couple weeks ago (several times after putting the belt back on) so I assumed I might need a new belt as it might have dried out at the store. I ordered new belts and today I used it for about an hour and the belt came off again, twice. There doesn’t seem to be anything to hold the belt on the stem as it seems to slip off. I have tried it centered, to the left and to the right….can you help. I am v
ANSWER : I’ve successfully used a compatible belt – Royal 104425001 .It’s still new, but for the time being at least – it works.

Brush Roller Wondering if I need a new brush as well as a belt. The Roller seems to have trouble spinning when it makes contact with the carpet no matter how the height is set. Everything else seems to work fine. Do I need a new roller to fix this problem?
ANSWER : The bearings can go bad in the brushroll. It may need replaced, even if the brushes aren’t worn. Helpful link….
