How to Identify and Fix Common Vacuum Problems ?

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

`Tripped` reset systems are the most common reasons for a brushbar not turning, but there are some other less common reasons too. These include: If the bearings on the end of the brushbar have seized, you won`t be able to turn it at all. This will often result in a broken belt as well, so be aware of this.
After a year or so, you may need to replace your vacuum`s beater brush. If the bristles seem to be squished, broken or are varying heights, it`s time to replace the brush. These can be found online with the vacuum`s brand and model of your vacuum cleaner.
Clear the brush roll of any hair and debris and inspect by placing it on its end and spin. The brush should spin freely. If it doesn`t spin; it may be time to replace.
The roller brush is the combination of a belt, a roller, and sometimes a small vacuum head motor. The roller spins, and the bristles attached to it sweep up debris that then gets sucked into the dirt container of the vacuum. The brush head also helps to pull dirt and debris out of carpets of various pile heights.
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.
Remove the brushroll and clean all hair, string, and lint from the brushroll bearings. If the vacuum cleaner brush still doesn`t spin after you clean the brushroll, consider replacing the brushroll.
A vacuum cleaner`s brush roller also called the beater bar assists in cleaning your carpets and depending on your vacuum model, a variety of floors. The brush roller is usually located under the vacuum cleaner and some in the attachment tool.
The replacement process is easy – pinch the sides of the brush head to pull it off of the handle and then replace it using the same process. I love that my bottle brush looks fresh and renewed!
The rotating brushes move counterclockwise together, trapping and absorbing the dirt that is deep in the carpet fibers.
Inspecting the Vacuum Commutator for Motor Brush Problems

Test that by turning the motor off and pushing on the center shaft, the armature. If it has any play, besides spinning, then replace the motor. If solid then replace the brushes – motor brush replacement instructions.

A: The drive belt is very tight and somewhat difficult to install. Q: These belts break after about 5 uses. I vacuum every day.
The Benefits of Using a Counter Rotating Brush

Carpets: The rotating bristles of a counter rotating brush rejuvenate matted carpet pile. It removes pet and human hair, dust, and anything that the vacuum cannot reach because it is below the surface as the bristles comb every fiber in the carpet from the base to the tip.

If the Side Brush is not spinning after cleaning, you may need a replacement Side Brush Module. Please visit the iRobot Store – Parts and Accessories, contact iRobot Customer Care, or use an authorized retailer or partner.
Almost every time that the brush stops turning, it is because of hair wrapped around the brush roller. You will burn out the belt if you use it too long in this mode. Your only fix is to take it apart and and clean it (and cut any hair stuck in it in the process).
If the cleaner is still not picking up water, you may have to rinse out the various parts with water before continuing. Try to rinse out the water tank, including the foam filter, and also rinse out the nozzle as it may have clogs in it. Make sure the circular hose tool connection door on the nozzle is closed as well.
Unplug your machine to reset the brush. While unplugged, remove the brush window and brush roll from your machine, by pulling the tab. Take out the obstruction that was causing the machine to stop working. Once the obstruction is removed, you may reassemble the brush roll and brush window.
Inspect the belt to see if it is broken, stretched out, or out of place. If the drive belt is broken or stretched out, replace it. If the brushroll is sticking, it will cause too much friction and put too much strain on the belt. Remove the brushroll and clean all hair, string, and lint from the brushroll bearings.
Burning smell can indicate motor damage

If you suspect that the motor is damaged, you should not continue to use the vacuum cleaner! The cause of motor damage is usually wear and tear or damage caused by prolonged improper use (e.g. overheating). In most cases, it is not worth repairing.

A carpet beater bar is essentially a floor nozzle for a vacuum equipped with a rotating beater bar that spins while the vacuum is in use. By spinning, it agitates the carpet and loosens any lead dust that might be stuck in carpet fibers.
A: Beaters are to mix up things like cake mixes,butter ,whipped cream ,a whisk puts air into what your making like meringue ,omelets, dough hooks are for heavy items like dough, pasta.
To replace the brush head, twist counterclockwise 90° and pull away from the handle. Slide on new Spinbrush replacement head and turn clockwise 90° until arrows are aligned.
A good rule of thumb is to change your brush every six months, said John Stevens, research and development lead of Goody Hair Products. If your brush`s bristles are starting to separate or melt, or the bed is cracked, it may also be time to move on, he said.
A rotating toothbrush works best if you brush each tooth individually. The round shape of the brush head comes out best if you actually encircle every tooth. This requires a different way of brushing than you`re used to with a manual toothbrush. That`s because you`ll have to press the brush head onto each tooth.

I have a hoover windtunnel cyclonic model #5780-900. The beater brush will not spin. I have replaced the belt but it doesn’t seem to engage when put into vacumm position.

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!

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.

Hoover Wind Tunnel 7500 Brush not Turning. I have replaced the Brush and the belt. The problem does not seem to be either to me. I believe might be a missing part. The place were the belt hooks on is a metal pole which never seems to grip the belt well. In fact it seems loose most of the time and slips on the brush, causing the belt to eventually burn up. Could there be a missing plastic or rubber piece meant to hold the belt taught  on the metal pole?
ANSWER : Check the Idler Pulley part Number 43241004 (Item 13 in the IPB)

We have a Hoover upright vacuum cleaner, model Core 7. There is a switch that turns on and off the brush drive. This operates via a cam with a bearing putting pressure on the final drive belt to engage the brush head.

My brush head is not turning and with the lever set to engage the drive there is still considerable slack in the final drive belt.

There appears to be only a bearing deflecting the belt, should there be a pully or other device mounted on this bearing? There is so much slack a

ANSWER : Yes, there should have been a white plastic sprocket on top of the bearing – in its channel the belt would sit. Unfortunately no parts are available for this unit that can be bought retail – only available by order to dealer repair shops....
Unfortunately to fix it you must send it to one and that would be more expensive than a new one. Just junk this chinese POS and buy another chinese POS.

Replaces the belt on dirt devil dynamite pluse model put everything back together started it and it burt the new belt up that fast. I put it around the beater brush and the metal bar I thought it should go around, yet it seemed like there should be something else there to put the belt on. What do you suggest? Do you have picture I could go by?
ANSWER : The metal bar you put it around if the bar itself does not spin it is going to burn the belt up. Every thing that the belt is supposed to go around has to turn or the belt will rub on the piece not moving and brake.

I replaced the belt in our Eureka Boss Smart Vac, it still seems loose, it uses a type R belt. The beater belt still doesn’t seem to turn properly and seems that it doesn’t pick up very well when I use it on my berber carpet. We have 2 dogs and I like to use it frequently. I have changed the bags and belt……
ANSWER : Check to see that the beater brush is not frozen up. Pull the brush and clean it, spraying some WD40 on each end piece that holds the brush in place..Also be sure the belt is properly installed so that the brush turns in the correct direction..If the brush is not turning or not turning in the correct direction, it will not beat the dirt from the carpet so that it can be picked up by the vacuum’s suction.

I’m using (or WAS using) a Eureka ”the boss” model 8803. The belt broke, no biggie, so I replaced it with a Eureka model U belt, the problem is when I put the new belt on and turn on the vaccuum, the belt breaks again. I am also having trouble getting the brush roller to fit right when the belt is in place. I can’t find any sharp edges that would cut the belt,nor can I find where any small bits may have broken. Anyone have a solution for me?
ANSWER : First, make sure you have the right belt, second, i am thinking that you are not lineing the roller up right, it will only fit one way. look at the ends of the roller and the grooves where it slides in, you should be able to see clearly how it goes.
