the belts and they looked okay and no hang ups of string or anything. The only thing that seemed weird was that the smaller belt that actually attaches and turns the roller is a bit loose. The larger belt is tight but looks like its the one that is burning and causing the smell.

How to Identify and Fix Common Vacuum Problems ?
Our sources include academic articles, blog posts, and personal essays from experienced Vacuum Technicians :
If you checked your brush roll, floor setting, and belt but your brush roll is still not spinning, that means you probably need a Shark micro switch replacement. This small switch tells the vacuums brush when to start spinning.
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.
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.
Most cases of a jammed or stuck brush bar are quick and easy to fix, simply pulling the debris gently from the brush bar. Alternatively, if you need to clear a problematic blockage, you can take the brush bar out of the housing easily, for quick maintenance.
Why does my Shark vacuum keep stopping? For Shark robotic models, odd sweeping or sudden stops can often be a result of dirty vacuum sensors. These sensors can often be found on the bottom and sides of the vacuum. Hitting them with a soft cloth should be enough to remove any excess dirt.
Check the hose for any clogs
If your Shark vac has a hose, feel along the length for any lumps. That indicates a clog that`s causing your suction issues. See if you can break the clog by applying gentle pressure with your hands, or gently move it to the end of the hose to remove it.
1. Motorized Brush Head. Sometimes called the “power nozzle,” this large attachment has a rotating brush to clean carpets more like an upright.
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.
Ceilings and Drywall – Medium 3/8″ nap roller covers work best. Walls, Wood, and Metal – Small 1/4″ nap roller covers or foam rollers will produce the smoothest finish. Light to Medium Textured Surfaces – Microfiber rollers are best. Smooth Surfaces – Use a white woven short nap roller for an ultra fine finish.
Next to the motor, the belt on your vacuum is just about the most important part of your vacuum. Without the belt to spin the brushroll, most vacuums won`t pick up on carpeting at all! If your vacuum uses a rubber belt, check it once a month for cracks, melting, and especially, slippage.
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.

the most relevant questions and answers related to your specific issue
The brush roller stops turning and I can smell the belt burning, then it will catch and start working normal. I looked under the plate to check the belts and they looked okay and no hang ups of string or anything. The only thing that seemed weird was that the smaller belt that actually attaches and turns the roller is a bit loose. The larger belt is tight but looks like its the one that is burning and causing the smell.
ANSWER : Better to replace both belts the smaller one is stretched out thats whyits slipping ,be sure to clean the old rubber off the motor shaft before replacing the belts.it will cause the new belts to run unevevly and go bad before their time

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!

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?

The original belt on my upright Kenmore Progressive broke and I replaced it with the spare that was in the vacuum. The vacuum and spare belt are about 10 years old. Then the spare broke after one vacuuming session and there was a burning smell coming from the vacuum. I ordered new belts and replaced it with the new belt. It seems to be working fine with no smell. I checked the belt after I vacuumed the family room and although it was in tact, the belt was very hot. Is that normal? Should t
ANSWER : The belt heats up due to the friction, as well as being in contact with the shaft of a hot motor. It is normal.

Motor is sparking and smells like burning rubber. When it first happened I thought the vacuum had something jamming the beater bar. That was the smell it had, like when the belt gets burned. But when we turned it over, it wasn’t jamming. Took off the base plate and turned it on. The motor area is sparking and it makes a weird noise (I assume that is because the motor fails and restarts). I looked for loose wires, can’t find any. I believe I need some sort of part replaced, maybe even a n
ANSWER : From sound and description most possible is motor is burnt up sparks usually mean metal on metal either bearing or bushings went on motor if u can jiggle the shaft thats bearing if u rotate the shaft by hand and feel and or hear rough grinding the brushes are damaged and the (windings)are also would need to replace motor oreck has a costumer service 800 989 3535 number give them a call not always but some times they will ship a replacement part for free

Burning smell There is a burning smell when I run my Kirby Ultimate G. The smell seems to be coming from the belt. I looked at the brushes and they are spinning so the belt is working. the Post on the vacuum is getting very hot not sure if that is normal. What is causing this?
ANSWER : Unlock the sweeper brushes and take them out. on each end is a cup bearing and should be free of debris.
then check around and under the belt and likely there is debris wrapped around it.
the post is getting hot as your pulling too much of a load.
though if it continues the motor may have a bad set of motor brushes (inside the motor) or bad wiring (kinda unlikely).

Hoover windtunnel t series belt is loose- roller brush doesnt turn.
Its brand new belt is slipping. we bough new belts and putthem on same problem. Can not find solutio in manual.
Is the belt supposed to go around the “metal pulley”. I know it goes around the little metal motor thing, then thru the guide and around the brush.
What is the metal pulley??? Is is the larger round silver thing between the guide and roller?

Floor Attachment I took off my floor attachment, but now the belt seems to be off and I can’t seem to get it back on right. I can’t use the attachment and I don’t know why it’s so hard to figure this out. They say, just turn it to belt off, but when i turn it it lift’s it up and can’t line up with the belt off label. Then, when I turn it the other way, it’s off. So I’ve been trying to pull it off so when it lines up with belt off, it’s off. But the I turn it the other way and it’s still off a
ANSWER : Try this,

.With the floor nozzle off the machine spin the belt lifter around until the red arrows match. If you look at the side that attaches to the vacuum you should be able to see the belt up on the hook. If is not on the hook offf the machine you will never get the belt on. Once the belt is on the hook attach the floor nozzle to the front of the machine. At this point you need to spin the belt lifter back to where the green arrows match. Oh and another suggestion make sure your hieght adjuster the pedals with arrows are all the way up. Hopefully that helps you out.
