Replacing broken or stretched drive belts is one of the most frequent repairs for canister vacuums. Inside the motorized carpet-cleaning head, a rubber drive belt connects a small motor to a spinning brush that beats the carpet pile and loosens dirt to be sucked up into the machine.
Vacuum belts connect to the brush roller and assist in collecting debris. On the other side of the belt is usually the drive shaft or motor pulley. After regular usage, the belt will stretch out, lessening the tension on the brush roller. Lesser tension diminishes the brush roller`s turn rate and speed.
(All full-sized machines, upright vacuums and canister vacuums, typically have a belt.) A vacuum will still create suction with a bum belt, but without a rotating brush roller, it won`t collect much in the way of dirt and debris, especially on carpets.
Their operation is simple: A belt is connected between an electric motor and a vacuum motor, linking their rotation. The built-in electric motor does not create vacuum itself, but rather it spins the belt around the vacuum motor. The vacuum motor once spun, creates a vacuum for your system using internal vanes.
The major types of vacuum belts are determined by their different shapes. As vacuum designs have improved over the years, new belt shapes have been developed to increase both their durability and their ability to transfer power from the vacuum`s motor.
When the engine is running, the crankshaft pulley turns, allows in drive belt to turn all of the other pulleys it is attached to. There are two kinds of drive belts: V-belts and serpentine belts.
Below are the functions of a belt drive and pulley in their various applications: The primary function of a belt is to transfer power (rotary energy) from one source to another. Whereas pulley that has a groove around its circumference allows a belt to smoothly through it when transmitting rotational motion.
The belt drive mechanism is a rotation transmitting mechanism for transmission of rotational drive force. The belt drive mechanism includes, for example, a drive pulley, a driven pulley, and an endless belt wound between the drive pulley and the driven pulley.
If your new belt is too loose, the brush roll will turn slowly, and the vacuum won`t do it`s job. If it is too strong or tight, it puts excessive wear and strain on your motor and bearings which can cause damage, resulting in unnecessary repair costs.
Before you spend your time trying to go back over the same areas, hoping you`ll get it all cleaned up the second time around, check out your brush roll and belt. If you`ve cleaned your brush of any sticky stuff and hair, and it all looks fine, you`re likely dealing with a stretched belt.

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.

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 have 2 Hoover Wind Tunnel-self propelled bagged vacuums-U6433-900 model.The roller bar does not agitate, the self propelled feature does not work and, in general, the vacuum is not performing well. I have replaced the roller bar, the v belt and the wide belt. The filters have been replaced and it has a new bag. I have had both of these since 2004 and they were fairly expensive $200 each) but if the repairs are prohibitive, I might as well get new vacuums. Suggestions? I just spent $100 for bel
ANSWER : The Hoover WindTunnel self propelled is a machine that we see in our retail stores (Vacuums Unlimited) constantly. The benefit of having a supposed “self-propelled” machine wears of quickly after the numerous time you will need to take this machine in for repair.

It’s unfortunate you’ve had to spend so much money already on repairing this machine. I know you’ve said you’ve already replace the belts and filters, but if you want you can check out a video we made on repairing the Hoover Windtunnel.

If you are looking for a reliable upright, at GoVacuum we’d recommend the Sebo X4 upright (http://www.govacuum.com/seauxseupvac.html). The machine is incredibly reliable and easy to maintain. Thus far, we haven’t had one warranty repairs come through our doors. The machine itself has a lifelong warranty on the belt because the machine automatically shuts off the motor if an obstruction is detected, preventing any undue stress on the motor or belt.

I have a Hoover power max self propelled vacuum. The belt that goes to the self propelled part keeps slipping off. I’ve had the belt replaced, but the problem persists.
What can be wrong? I’ve taken it to a Sew N Vac repair, but all he did was replace the belt again. And it still has the same problem.
ANSWER : I can guess of one problem

belt gets removed when motor is running right?
am assuming that belt is fit tightly and fits correctly when motor is in rest

if so then ur motor is not running at a proper speed which can be a possible reason for making the drum to slip from its place.

else ur drum which holds the belt is some what mis aligned from its normal position.

I purchased a brand new Eureka Pet vacuum, sorry don’t know exact name but it the one that has the self cleaning duster on it. Last night I used the vacuum on my carpet, it was working fine until I accidently sucked up the corner of a scarf that was hanging off a couch. I shut the vacuum off, pulled out the scarf and and resumed vacuuming. Much to my dismay the suction on the vacuum had ceased. Can you tell me if there is a reset button on the vacuum? The vacuum does not appear to be damage
ANSWER : If the motor is running, there should be suction. Possible problems depend on whether it’s a canister or upright and are:
.A clog in the hose, UR or canister. Detach hose. Drop small coin in one end and lift hose causing it to roll out the other. If it does, no clog in hose. Drop same coin into hose opening on power head. If it rolls out, no clog in PN.
.Broken fan blades, UR. Needs to be taken to shop for repair/replacement.
.
.A reset button is for use if the motor isn’t running, so won’t have anything to do with the suction.

On my hover U6616-900 the self propell work fine on the med setting on med height carpet, but when I go to low height carpet and height set on med the self propell does not pull the vacuum and it is hard to push. Also if I raise the height to the highest setting the self propell works correctly and appears to clen. Any ideas? S/N 090400184555, think this vacuum is maybe 5 years old and my wife uses it lots. Should I think of maybe a complete overhaul or a replacement at this time?
ANSWER : This is a typical problem you are describing. I would recommend you change the belts, this will resolve the “hard to push” and most likely resove your issues. based on the s/n given you maching was made on sept 2004.

Is there any way to repair or replace the belt GUIDE on the inside of the belt compartment of a ’97 Hoover Wind Tunnel (not self-propelled)? It became twisted when a belt broke and now the belt rubs against it and sounds really weird, and I’m sure new belts will continue to break.. This guide is a long piece of molded material (part of the compartent wall) to keep the belt from coming off the pulley. It also had a sort of metal clip on it. It was loose and I took it off because of the way the pa

Belts I have a Hoover self-propelled windtunnel, purchased 6-04. It gets light use. I have replaced the v belt 3 times, once under warranty, and it must be replaced again. It appears to be in very good condition, but is stretched too big. When I purchased 2 v belts a year ago, one was already too stretched,but when my Dad took it back, the salesman put it on another model and said it was fine (Dad never mentioned this to me). Is there a way to adjust the vacuum to hold the belt tighter? Do t
ANSWER : It is the flat belt that gets stretched and should be replaced at least every 6 months. The V belt wears down so it won’t it right in the brush roll V. Maybe the belt tensioner wheel has a problem, sometimes they get hook up and won’t engage the V belt. Check the brush roll also, if where the V belt rides in is covered up with belt, replace it. There is no adjustment, doesn’t need it if everything is working the way it should.
