How to Identify and Fix Common Vacuum Problems ?

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

The bearings in the brush rslip. oll or bearings behind the fan could cause this. If you put the belt on and the brush roll is catching it would cause the belt to slip. If you have any a height adjustment it could be an issue.

Rollers Are Worn or Misaligned

Another common roller-related problem is debris buildup. Sandinggenerates a lot of dust, and some of it can end up on the rollers, causing the belt to slip. Remove it and carefully clean any caked-on dust before using the sander again.

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.
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 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.
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.
The worn-out spring inside the lever causes it. Remove the belt sander and the screws next to the tension lever to fix this problem. Then remove the cover, swap out the lever spring for a new one, and assemble everything. This will fix the tension lever problem.
Too much wear due to heat and friction will cause a serpentine belt to break over time. That`s why regular inspections are vital to making sure this doesn`t happen.
During operation, if the belt comes off the sheave or turns over, this can indicate misaligned pulleys or contamination in the drive. Other conditions that can cause the belt to jump off the sheave or turn over include insufficient belt tension, significant vibrations in the drive, and shock loads.
Have you ever broken a belt on your vaccuum and didn`t have a chance to buy a new one? You can make your own out of duct tape for a TEMPORARY fix. This belt is for TEMPORARY USE ONLY, you might damage your vaccuum if you overuse this belt.
An overloaded washing machine or clothing jammed in the rim of the washer drum can cause drive belts to slip or burn. Find the problem, then remove the belt and install a matching replacement belt.
Belt Problems

This scenario is often caused by a sock or other small article of clothing that has become wedged in between the drum and its housing, thus preventing the drum from spinning. Similarly, if the machine has been overloaded, the drum may not be able to spin correctly.

The drive belt on your washing machine is responsible for turning the drum via the motor. If your belt breaks or is slipping then your washing machine drum will not turn or spin.
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.
Drive belts always stretch a little in use, because of the strains put on them by driving the water pump and generator , as well as the fan itself if it is in the system. Age and continual flexing also cause belts to crack and deteriorate. Stretching slackens a belt, so that it slips on the pulleys.
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.

The most common cause of belt coming off

A loose drum pulley is the most common cause. The pulley should not be able to be moved, apart from obviously round and round as it turns the drum. It should be bolted firmly to the drum spider with no play in it.

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.

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!

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

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.

Hoover Windtunnel – the belt keeps coming off & it is the correct
ANSWER : One compatible belt that I use and works (at least while its new) is Royal 104425001. Try that.

Belt keeps coming off.
ANSWER : The dowel that the belt attaches to should have a slight “V” in it. This prevents the belt from slipping off. Check that, if it isn’t there than you may need to replace the dowel. I own a Bissell and every 6-8 months replace the belts anyway as preventative maintenance is my philosophy.
