Hoover U6630-900 WindTunnel Bagless Upright Vacuum\015 I just had this unit serviced a month ago, with new belts. The brush roller now isnot turning, but it was working last night?! I opened the bottom and found that the small belt that turns the brush roller is stretched out. There is no tension conveyed to the roller brush as a result. Should this smaller belt be positioned around the small black plasic height adjusting stem, located beneath the stainless stem that is turned by the big belt? I tried this and now, when I try to run it, there is a smell of burning rubber and the roller brush still does not turn. This unit has the red ‘dirty,’ green ‘clean’ sensor lights; now, only the red is on. Sounds like I need a new belt, but it’s only a month old?! Help, please? Thanks. The shop that did the work won’t be open again til next week.\015
How to Identify and Fix Common Vacuum Problems ?
Our sources include academic articles, blog posts, and personal essays from experienced Vacuum Technicians :
Should the brush not rotate freely there may be debris tangled around the ends of the brush, carefully remove any obstructions or replace the brush with a new one. We recommend that you fit a new belt and brush once per year to keep your Reactive vacuum working efficiently.
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 the Rotator Brush and Wheels Sometimes pieces of string or other objects get wrapped around your vacuum`s rotating brush or around the wheels of the vacuum. Unplug your vacuum. Turn it over and have a look at the wheels and brush. If you see any pieces of string or objects lodged there, remove them.
A Revolving Brush Roll
Greatly Enhances Carpet Cleaning These brush rolls revolve at a very high speed, agitating the carpet fibers in the process. The effect of this is to loosen dirt and move it toward the top, aiding in its removal from the carpet fibers.
There is no one-size-fits-all belt sizing formula. Belts fit differently depending on user sizes and gear combinations. For instance, gun belts measure different standards than a regular size guide due to the flexibility of various holsters. The intended use influences your choice of shapes and even material.
Next to the motor, the belt on your vacuum is just about the most important part of your vacuum. Without the belt to spin the brushroll, most vacuums won`t pick up on carpeting at all! If your vacuum uses a rubber belt, check it once a month for cracks, melting, and especially, slippage.
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.

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.
One of the easiest ways to increase vacuum cleaner suction is to empty the dust bag or container. Dust containers need to have enough space for airflow, otherwise, they could get clogged and have less suction power. Regularly check your dust compartment and empty or change it when it`s already 70-80% full.
Clear the brush roll of any hair and debris and inspect by placing it on its end and spin. The brush should spin freely. If it doesn`t spin; it may be time to replace.

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!
Hoover WindTunnel, month-old belt, now too large to turn brush
ANSWER : I suspect you have been bitten by the Chinese bug..
.A very large percentage of replacement parts for all manner of appliances and vehicles are now being conterfeited in China who we should know by now has no respect for the intellectual property of others and a flood of low-quality stuff is being made as ‘knock-offs’ since they are generally easy to fabricate with fairly primitive means..Our eldest son just returned a supposedly ‘new’ steering pump for his (US) car but this one at least had China as the origin shown on the package..
.Make sure though that the brush roller turns freely and isn’t being impeded by trapped thread in the bearings.
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.
Hoover Wind Tunnel 7500 Brush not Turning. I have replaced the Brush and the belt. The problem does not seem to be either to me. I believe might be a missing part. The place were the belt hooks on is a metal pole which never seems to grip the belt well. In fact it seems loose most of the time and slips on the brush, causing the belt to eventually burn up. Could there be a missing plastic or rubber piece meant to hold the belt taught on the metal pole?

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
Hoover windtunnel t series belt is loose- roller brush doesnt turn.
Its brand new belt is slipping. we bough new belts and putthem on same problem. Can not find solutio in manual.
Is the belt supposed to go around the “metal pulley”. I know it goes around the little metal motor thing, then thru the guide and around the brush.
What is the metal pulley??? Is is the larger round silver thing between the guide and roller?
ANSWER : I also have a loose belt and have bought additional belts but have the same problem. I put the it around the metal rotor and around the brush roller a shown by he Hoover video, and it is loose.
I have the bissell power force bagged upright vacuum and the brush is not turning, I have replaced the belt but the brush will not move but the metal piece that is hooked to the motor that spins the belt and brush is turning but the brush won’t, and the belt starts to burn
ANSWER : Sounds like your brush roll is seized. Remove the brush roll (see picture) and make both of the end caps spin freely. If not, replace it and you should be set.
*An example of a brush roll*

Make sure that the brush roll spins freely.
Hope that helps.

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.
