    Altho my model is U5465-900 it is a self propelled wind tunnel Hoover. The small belt drives the brush; mine seems very loose and the brush stops turning with very light resistance. The manual says "Belt may fit loosely when properly installed." but mine is so loose the belt pulley just spins under the belt.

    We had owned our Wind Tunnel 2 (model U8347-900) under a month and the "lifetime" belt became so loose it no longer would engage the roller brush. I see no easy way to tighten or replace the belt.

If this is a "V" belt, make sure the small roller that tightens the belt is ok and not jammed up. It may have to be replaced. Also if the flat belt is stretched at all, it won't work either.

    Am i correct in that the belt goes around the pulley (beside the other belt) and then stretches onto the brush roller?

Call the Bissell Consumer Care at 1-800-237-7691 something doesn't sound right. Are you sure you followed the detailed install instructions that should have come with the new belts? I'd check that first and if you did then call them.

Vacuum problem

Most vacuums have a belt that drives the brushes and most problems are caused from the belt being worn out and slipping or completely breaking in half. Also could be dirt up in there and jamming the belt.
Most likely you need to replace the belt and when you do give the vac a good cleaning in that area.

Why does Beater Bar Fail to turn

Per owner's manual
1. Make sure the brush control is set on carpet mode.
2. The brush will only spin when the handle is reclined.
The belt has worn out and needs replaced. Although it appears okay, stretching is possible, which would result in too loose a grip to turn the bar.
If the belt was replaced, it may not have been pulled tight enough to turn the bar. To tighten on many vacuums, simply loosen the screws on each end of the brush, pull toward the front of the power head and hold while tightening the screws.

I just replaced my hoover belt and it is too loose to make the brush spin. Is there an adjustment to tighten the belt

Greetings from GoVacuum,

The belt is going to be loose as long as the vacuum cleaner is in the upright posistion. If you have the vacuum cleaner with the handle locked in the upright setting, then the belt will be tight around the skinny belt. Once you release the handle of the vacuum cleaner, you can watch as the belt tightens over the roller brush. There are numerous problems with this particular model. We have recorded a very helpful video review of how to replace the belt, and do basic maintenace for this particular model. Hopefully this will help you figure out the correct installation, and other maintenance work you can do yourself.

Here's the video;

If this still does not fix the problem, and the brush is still not spinning, please feel free to email me at chris.jones (at) I'm always more then happy to try and help you fix the vacuum.

Thank you very much,

The small belt attached to the roll brush keeps slipping off. It's a brand new belt and the vacuum is only 1 yr old.

The small belt rarely gives the problem you describe. The larger belt can jump off if the belt is worn or if th roller gets caught on something suddenly.The belt should be replaced every 9 - 12 months. If your carpet setting is too low this will cause the belts to wear faster that the estimated given time

Beater Bar Belt loose and bar won't turn

Provided that the motor isn't loose, the belt should fit tightly. If you had reassembled the beater bar back in the vacuum improperly, the belt would be tighter, rather than looser. If you are sure that the motor isn't loose and the beater bar was reinstalled correctly, then either tha belt slipped back off the motor shaft, or they sold you the wrong replacement belt.

Why wont the self propelled brush on the hoover wind tunnel work. large belt is ok. the small belt looks 0k.

no don't do that,have a little patience.check where the self propelled assembly is and see if anything got in there,something might be loose and the teeth are meeting each other.thats a good vavuum.i have 2 but their not self propelled.try taking the belt off the self propelled machanisn and try it again.if it works then something is keeping the propelled machanism from working.dig a little deeper,what do you have to lose?

I replaced the belt on the vaccum cleaner for the brush and it just seems too loose. How do I tighten it? Do you have a diagram I can look at. I lost my instruction booklet.

try using a smaller belt from a different manufacturer. not to much smaller. you dont want it to be extreamly tight just get one slightly smaller and try that. it dosnt have to be made by hoover. as long as it is not wider or thinner just about the same width and slightly smaller. i do it all the time with my vacuums to save money

I have a hoover windtunnel upright vacuum bought it a few months ago and now the brush spinning stopped working.

You probably have a broken belt, or the belt came off. The Self Propel Windtunnel has an issue with the pulley that tightens the V-belt in place getting stuck and needs to be taken apart and released, but most likely its just the belt. They should be replaced every 6 months or so, and the part number is usually on the serial tag of the machine.
