Underneath the cleaner is a brush bar that is driven by a rubber belt. It spins around sweeping and beating the dirt out of the carpet and up into the cleaner. The belt will stretch and wear out so it should be replaced once per year or sooner as a precaution if you feel the cleaner is not sweeping up effectively.
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.
To open the bag, you simply pull the zip apart. You don`t let the air in via the valve. All vacuum storage bags will leak in air over time – Neusu vacuum bags have been tested to keep out most of the air, with only minimal leakage, after over four months.

The engine drive belt is located on the front of your engine and is used to rotate the engine accessories. The belt is driven by the engine crankshaft, and while the engine is running, the belt turns with the crankshaft, which in turn rotates any pulley that the belt wraps around.
Serpentine belt replacement is easy because today`s automatic drive belt tensioners eliminate the need to loosen bolts or pry components into position for retensioning. Just rotate the tensioner, remove the old belt and install a new one.
We suggest to replace the belt every 3 to 9 months to ensure the performance of vacuum, the 2-Belt design can be easy for you to replace it, order once, last throughout the year.

Serpentine Belts

Your car`s serpentine belt is a long continuous belt that drives all your engine components. Newer cars use serpentine belts because they are easy to replace. Most serpentine belts need to be changed at least every 50,000 miles.

The belt may be broken or worn

If you pick up something sharp or debris gets jammed in the brushes then the belt may snap. Also over time your belt will stretch, so it`s a good idea to change your belt once per year to ensure the cleaner picks up dirt effectively.

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.
There are two belts you need to be familiar with when talking about car maintenance — the serpentine belt and the timing belt. The serpentine belt winds through your engine and carries power to several key components, including the alternator, air conditioning, and power steering pump.
Can you reuse vacuum seal bags? The quick answer is yes, especially if you`re using vacuum sealer rolls.
Better for allergies – Bagged vacuum cleaners are much better for allergy sufferers because there is no risk of this nasty bacteria getting released back into the air when you empty it. If you or your family suffer from pollen, dust or pet allergies, we highly recommend a bagged vacuum cleaner.
In general, bagged models tend to work more efficiently than bagless vacuum cleaners because they have an extra layer of protection for their filtration system. If someone in your household lives with allergies or asthma, it`s in your best interest to choose a model that will filter out the air as best as possible.
If you don`t vacuum your carpet, the dirt will break down carpet fibers and create a breeding ground for dust mites and bacteria. In addition, your home will begin to smell musty from the dirt, mites, and other organisms settling into the fibers.
The average life expectancy of a mid-range vacuum cleaner is about six years. You can fix or replace things like blocked filters, jammed brush rolls, frayed hoses, worn-out stick vac batteries and broken accessories yourself.
The Full Dust Bag Indicator in On

It is often recommended, however, that dust bags are replaced when they`re around two thirds full or once a month. Daily and extensive use of vacuum cleaners will create a need to replace dust bags more frequently.

Of the parts that will eventually need to be replaced in your vehicle, the serpentine belt is one of the most important. How long does a serpentine belt last? Being made of durable rubber, a serpentine belt can last anywhere from around 50,000-100,000 miles.
The quality of the leather is one common factor: calfskin is the most common material used for belts, and a good belt will have a soft, supple leather. Flex the belt to make sure it hasn`t turned brittle or started to crack.
Drive Belt Sizes

All V belts should be measured across the depth of the belt and the top, thick section. To measure a V belt correctly, this means that you would measure the widest part of the belt (the thickest section), and then measure from the widest to the narrowest parts of the 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’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.

When selecting the carpet cleaning mode, it appears the belt is slipping (due to the noise) over the drive pulley. How do you access the drive mechanism to replace belt or inspect drive pulley and belt condition?
ANSWER : On those units you must replace the clutch assy. you cant just replace the belt. there is also a special tool used to get the new belts on the brushbar. If you would like me to walk you through this repair let me know.

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.

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
ANSWER : Honestly you should take it to a vac.shop they can fix any vac.

Hi my proheat bissell 7901 stopped pumping water to the floor, but it pumps water from the hand hose. I read the manual and followed how to check belt and the flat belt on right side of shampooer is fine and I turned on and it turns and so do the brushes at the bottom of the machine. I was reading online and I guess there’s two belts on this machine? where can I find the other belt to see if it needs replacing. I guess it’s a ribbed belt? that is the water pump belt?
ANSWER : Just taken ours apart with the same problem… found it was caused by the 2 halves of the main casing coming apart in the area where the upright pedal release is. I found this to be due to the upper casing having broken in 2 places – the bottom of the screw wells..This means that the water tank cannot exert sufficient pressure on the valve to release the water..Only solution is a new top cover assembly

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.
