How to Identify and Fix Common Vacuum Problems ?

Belt tension adjustment is an iterative process that requires removing the Drive Belt for each incremental tension adjustment. The process entails: making a belt tension measurement, removing the Drive Belt from the motor pulley, changing the motor position to adjust the belt tension.
Belt tension is measured by plucking the belt span while holding a sensor close by. Belt tension is adjusted until the belt span frequency, or measured tension level is within manufacturer`s recommendations.
Belts that are too tight put an excessive load on pulleys, shafts, and bearings. Excessive belt tension will also wear out a belt quickly. Proper belt tension is 1/2 inch of sideplay both ways. Press down on the belt midway between pulleys and observe the travel.
A loose drive belt can compromise your vehicle`s ability to power accessories like power steering, air conditioning or your alternator, or could possibly even cause internal damage to the motor.
Put it to the Flex Test
Your serpentine belt should be bendable without creating creases in the belt. If you have the belt off the engine, flip it so the toothed-side is exposed and bend the belt. If you see even minor cracks or stretches, it is time for a new one.
An over-tightened belt can burn out any bearing that the belt rotates on, including alternator, power steering pump, A/C compressor, idler pulleys, etc. An over-tightened timing belt can ruin any pulley bearing it is connected with.

iFrictional resistance = µRN + µRN = 2µRN = 2µR/2cosec α= µR cosec α = R ⋅ µcosec αSince in flat belt frictional resistance is equal to µR and in case of V-belt µcoseca X R So Ratio of Tension in V-Belt:: T1/T2 = eµ.
Typically a damaged belt tensioner will not impact vehicle performance. It would cause the serpentine or drive belt to wear prematurely or to squeak – but not cause the acceleration issue.
If a belt is not tensioned properly, it will ride too loose or too tight on the pulley. A belt that`s too loose on a pulley will cause slippage, which leads to heat build up from friction. This heat will damage your rubber belts and cause the belts to crack and break.
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.
Yes. The car is propelled by the engine through the transmission. The absence of drive belt won`t stop a car from moving from its stationary position but it will affect the operation of the engine which will cause it not to operate for long.
Misalignment and bearing wear can cause the belt to track off-center and will cause it to wear quickly. Check the tensioner and idler pulley bearings by removing the belt and spinning the pulleys by hand. All pulleys should turn freely with no binding, roughness or wobble.
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.
Check that the brush bar is clean and not damaged
If the cleaner becomes noisy or starts vibrating, it may be because some debris has got tangled around the brush roll or agitator situated in the bottom of the cleaner.
If too much hair, string, or lint is caught in the brushroll, the brushroll can get stuck. If the brushroll is stuck, it will put too much strain on the belt and may cause the belt to break. Remove the brushroll and clean out any debris from the bearings. After replacing the brushroll, make sure that it turns freely.
We know that the force of tension is calculated using the formula T = mg + ma.
Belt tension is the force that keeps the belt in contact with the pulleys and prevents it from slipping or sagging.
How you tension a belt at installation will determine how long the belt will run. Too little tension results in slippage, excess heat, and premature belt & pulley wear. Too much tension results in excessive stress on belts, bearings, and shafts.

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!
