I have the same problem. I believe, after some inspection, that the mechanism which allows for the circular spin of the brush has failed. Though I'm no mechanic, I believe my girlfriend's long (and beautiful) hair became entangled underneath the gray "end-cap" causing breakage of the rotating mechanism (which I believe is normally housed within the brush under the rectangular "end-cap"...the other "end-cap" piece is circular). Now the brush will spin about 6 rotations but with each spin the gray "end-cap" will extend on its screw rather than spinning freely. I believe my only option is to order another brush. We'll see if it solves the problem.

It certainly sounds as though the belt needs replacement. (Part # 38528035) If the belt has stretched, it will slip, causing a burning rubber odor. Get a new belt and compare it to the used one.

Hoover windtunnel U5453-900.belt melted put another belt on brush was spinning.Brush spins but not easily.It spins then stops therefore burns the belt.How can i get the brush to spin around better


Kristie,
I would suggest taking the brush bearings at each end off and clean any lint or hair that might be in the ends of the brush. If you have regular ball bearings on your brush, you might need to replace the brush roller if the bearings themselves are tight. Hope this helps!

Hoover UH70935 windtunnel agitator spins like crazy with plate off after cleaning but will not with plate replaced.... what is going on?


If the brush roller was removed, it may have been reinstalled incorrectly, causing it to bind on the bottom plate.

Changed belt. have burning smell


Take it back apart, check it again. Check the plastic where the belt is running for burnt spots. Also check the brush roller sometimes the tension from a new belt can finish off what was left of the bearings and cause the plastic end caps and roller to melt. Pull out the roller and try to spin it while holding the end caps. If it doesn't spin or spins hard there's your smell. Most times when the rollers go bad they break the belt. Replace the roller if necessary Make sure the roller is in correctly and flush and that the bottom plate goes on easily.


Good Luck

Belt slipped on my hoover self propelled windtunnel


Please give additional information?
Sometimes belts can be mounted in 2 directions. If installed in the wrong direction, the roller will rotate backwards and the belt can come off. Also, it is possible that the belt has stretched. Verify that the roller spins freely with the belt off. If it doesn't, remove it and clean it and verify that the bearing are good.

Brush roller on windtunnel won't spin


It sounds like you need to replace the actuator arm or the cable to it. Look for Hoover part 43143046 for a start. I've got a similar problem.

Putting on a belt on a vacuum


Greetings from GoVacuum.com,

Replacing a Belt on an Upright vacuum can vary from model to model, but it is basically going to be the same for most upright models.

First you will need to access the belt. Most upright vacuums this is done by turning the machine upside down, and most you'll need to remove the bottom plate by unscrewing (usually 4) screws that hold the plate on. You should see screws that are closest to the actual roller brush, simply remove these screws, and take the bottom plate off. If the machine is a Eureka, or Kenmore, the top agitator housing will be removed from the top of the vacuum, not the bottom.

Once you have removed the bottom plate, or top agitator housing, you should be able to see the belt (or broken belt) along with the roller brush. Remove the broken belt. Make sure that you purchase the correct belt by taking the make, and the model number (located on the back or bottom of the machine). Please note that a broken belt may be 4-5 inches longer then a new belt, as they stretch a lot before they finally break.

Once you have the new belt, you will need to remove the roller brush. Pay attention to how the roller brush fits into the agitator housing, usually there will be fittings on the end of the roller that have to be put in a specific place, or in a certain way to work right. After the roller brush is taken out of the machine, you will need to wrap one end of the belt around a metal pulley on the opposite side of the roller brush. Most pulleys are located where the main housing (handle part) of the vacuum meet the the agitator (floor part) part of the machine. Anyways, wrap one end of the belt around the pulley, and then put the roller brush through the other end of the belt. This is where you'll need to put some elbow grease into it. You'll need to stretch the roller brush and belt so that the brush and belt are stretched back to the place where you took the roller brush out of the vacuum.

Once you have replaced the roller brush with a new belt around it, pull the belt a few times to make sure that the brush spins while you are pulling it, to ensure that the belt is not pinched, and is spinning freely.

I hope this helps. Here's a video showing how to replace the belt on a Hoover Windtunnel Self Propelled model; Feel free to email me if you'd like to send me the model number of your vacuum, this way I can be a little more specific, and give you part numbers. I have all belts for all vacuums in stock. Email; chris.jones@govacuum.com. 1-866-468-2288.

BELTS ON WINDTUNNEL VACUUMS


Greetings from GoVacuum,

Here's an instructional video that we made showing how to change the belt on a Hoover Windtunnel upright. If your model is not a self propelled model, basically follow the same insturctions, expect instead of placing the belt over the pulley, just put the belt through the roller brush, and stretch the roller brush back into the agitator housing.
Please feel free to send me an email if you have any other questions. My email address is chris.jones@govacuum.com.

Thanks,
