How to Identify and Fix Common Vacuum Problems ?

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

Because vacuum manufacturers do not share a standardized naming system for vacuum belts, using your vacuum`s model number is the best way to ensure an accurate belt order.
Most Belts are normally measured from where the belt leather folds at the buckle end to the middle hole at the tip end and are usually stamped on the back of the belt with the size example 32, 34, 36 etc.
First two digits indicate top width in sixteenths of an inch. Next two digits designate sheave angle, in degrees, that the belt is designed to fit. Last three or four digits indicate pitch length to the nearest tenth of an inch. Part numbers are derived from industry standard number.
If your vacuum runs but isn`t always picking up dirt, it might be time to change the belt. Consumer Reports` experts reveal how fast and simple it is to install a new belt which can save you a trip to the repair shop.
Founded in 1909 in Detroit, Michigan Eureka vacuums have been in American`s homes for more than a century. Now we`re building on that experience with innovative cleaning technology to help you clean for years to come.
Belt powerfully rotates the brusher bars in your upright vacuum. For optimum performance, change the belt at least every 12 months.
V-belt cross sections can be identified by their top width and depth dimensions. For example, a v-belt with a top width of 21/32” and a depth of 7/16” is a “B” belt. You can also use our Browning Belt Rule that includes a gauge to help easily identify belt type.
A Type V-belts with a top width of 1/2 inches. B Type V-belts with a top width of 21/32 inches. C Type V-belts with a top width of 7/8 inches. D Type V-belts with a top width of 1 1/4 inches.
How to measure the belt: You will notice that all V belts also sometimes referred to as wedge shaped belts are measured across the top think section and the depth of the belt. This means you would measure the widest part of the belt (thick section) and then from the widest part to the narrowest part of the belt.
It is simple.

Put the belt around your waist (make sure it is tight). Loop the end through the regular opening. Loop it under the rest of the belt around your waist… And then back over and through the hole formed by this process.

Belt repair can be complex, as each job is custom and completed by hand. Often, our craftsmen must sew through thick layers of leather to make a delicate repair.
You should replace the belts on your vacuum at least every three to six months if the vacuum is regularly used. This is very important for proper cleaning.
A reasonable cost of living

This is due to the city`s proximity to large agricultural areas and its relatively inexpensive housing. The city`s median home price is $362,600, which is way lesser than California`s median home price of $600,000.

Eureka products are made available from our Wuxi, China; Gothenburg, Sweden; and Ohio, USA stock. Our packing and boxes has been carefully designed for best product identification and to minimize logistic and retail handling costs.
Our journey into the outdoors began with products ranging from rugged canvas wagon covers and horse blankets to custom camp tents and store-front awnings – all crafted in our Binghamton, NY workshop. Quality and durability has always been our trademark.
(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.
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.
You will find your model number on a metallic silver sticker. It`s usually located on the back or bottom of the vacuum cleaner.
Our Verdict On Eureka Vacuum Reviews

Eureka vacuum cleaners are one of the most popular brands based on consumer reviews. Their 4870 Boss upright vacuum cleaner has been getting rave reviews based on its performance, maneuverability and durability.

A typical serpentine belt generally starts at around $15 and goes up to $80 at most. Add to that the labor costs that can range from $75 and $120. Altogether, you`re looking at around $90 to $200 (plus taxes and fees) to replace your serpentine belt.
Some manufacturers like GM or Mazda do not recommend giving a second chance to the belt once it has been taken off. On the other hand, Chrysler and Ford say the belt can be reused if there are no problems found with the belt.
The optimal length of the gun belt is determined by looking at your waist size plus how you carry. You typically want to wear a belt that measures four inches longer than your normal pant size. For example, if you normally wear size 38-inch pants, you may want a 42-inch belt.
In order to determine the belt datum length, simply add the pulley circumference to twice the center distance between the pulleys. When the belt is used to reduce speed or multiply torque, pulleys of different diameters are used.

Looking for Eureka belt 70646A for a Eureka The Boss upright
ANSWER : I just replaced the belt on my Eureka The Boss Smart Vac (Model 4870D). I purchased a namebrand Eureka R belt from a local vendor. I did my best to follow the instructions printed on the bottom of the machine. I turned on the vacuum cleaner and the belt brush was spinning! I dropped it into vacuuming floor mode and the belt wouldn’t spin no matter what level I put it on.
.
.I called the manufacturer (1-800-282-2886) and spoke with a very nice woman on the phone. While I was speaking with her I noticed that a silver screw was lodged within the “brush roll control” yellow selector switch. With some shaking it became dislodged and I was able to put the “brush roll control” into the hard floors setting and turn the “carpet height adjustment” all the way to the right, so that it was facing the word “low.” I then followed the instructions for replacing the belt again.. (1) remove base plate (2) remove brush roll (3) place new belt around motor shaft and then around brush roll (4) insert left side of brush roll before right side (5) rotate brush roll to be sure belt is centered (6) replace base plate, making sure to insert under 4 little tabs before securing with screws.
.
.It appears that it is very important that the carpet height and brush control adjustment are set to their highest point possible (hardwood setting) in order to get the brush to roll in a carpet setting.
.
.″R” is the correct belt for the 4870 and should be correct for all other 4800 models.
.
.Thank you for posting your problem to this website. If I hadn’t seen that others were having trouble, I would have just given up. I hope this long post helps someone that was in my situation.

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.

I have a Eureka 4870GZ. It turns on, but the brush roller doesn’t move. The belt looks fine. I do have an extra belt and would try replacing the old belt, but I can’t get the old one off the motor shaft or the new one on. I called Eureka customer service. The lady said there’s supposed to be a small space between the motor shaft and the outside edge of the vacuum where I can slip the old belt off and the new one on. I don’t see it. It looks like the motor shaft goes into a recessed place in the
ANSWER : Remove the top cover so that you can access to belt, You’ll find 2 rows of 4 decorative holes on the top cover, In two of the holes you’ll find the screws, Please use a flash light to see in that., Once the screws are removed, you’ll be able to take out the top cover. Pull the belt so that it should rotate the shaft and look for small space in between from where you can take off the old belt and new belt on. remove the agitator from its drive shaft, put new belt in, put the agitator back into place.

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!

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

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

I replaced the belt in our Eureka Boss Smart Vac, it still seems loose, it uses a type R belt. The beater belt still doesn’t seem to turn properly and seems that it doesn’t pick up very well when I use it on my berber carpet. We have 2 dogs and I like to use it frequently. I have changed the bags and belt……
ANSWER : Check to see that the beater brush is not frozen up. Pull the brush and clean it, spraying some WD40 on each end piece that holds the brush in place..Also be sure the belt is properly installed so that the brush turns in the correct direction..If the brush is not turning or not turning in the correct direction, it will not beat the dirt from the carpet so that it can be picked up by the vacuum’s suction.
