Either the brush rolls are bad, at the ends, or the gear/motor asm. is bad.

How to repair windtunnel hoover agitator that will not turn

Likely a broken belt. Also check the agitator brush roll bearings (in either end under the end caps) for hair, strong, thread, etc. as this will make the brush roll harder to turn and wear/break belts prematurely. If all these check okay, then observe the tensioning roller that causes the V belt (runs from the idler pulley to the brush roller) to be sure it is swinging down when the handle is released to hold tension on the belt, causing it to rotate. These tensioning rollers can break, but often are locked into the "Bare Floor" setting without the user noticing. Slide the carpet brush roll selector (located on top, next to the floor height slide adjustment) back and forth and make certain it is all the way into the "Carpet" setting to allow the tensioning roller to engage. [Note: The tensioning roller is always retracted (in the neutral or off position) when the handle is in the upright position. You must release the handle to allow this tensioing assembly to engage.]

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.

Why does The beater bar on my hoover continue to run in the upright position?

Hi there! Some vacuums do not come with the feature that automatically shuts the brushes off when in the upright position.. If your unit is like this, be sure to put the vacuum on the highest setting when using the hose. Also, because the brush-roll continues to spin, avoid tipping cleaner or setting it on furniture, fringed area rugs, or carpeted stairs during tool use. Hope this was helpful!

Dyson dc17 makes loud noise on carpet setting. It's like a high pitch ringing almost but won't make the noise on hard floor, only carpet setting. Ive checked for blockages and cleaned all parts but makes...

It is probably the brush roll motor making the noise. Remove the brush roll & belt and turn both motors on. If you do not hear the noise when both motors are running the noise is likely coming from the brush roll

On hoover steam carpet cleaner, the brushes do not rotate on low or high settings.

Follow these steps if the Brushes Fail to Spin
•If the brushes on your Hoover carpet cleaner fail to spin, there may be a problem---some sort of blockage---with the suction or with the belt that turns the brushes.
Turn the Hoover carpet cleaner over, and inspect the brush area. Debris, strings, or pet hair may be tangled in the rollers, keeping them from turning. Use a pair of scissors to cut away any obstructions in this area. Flip the Hoover carpet cleaner back over, and turn it on to see if cleaning the rollers has solved the problem.
To check the belt, turn the Hoover carpet cleaner over, and remove the bottom plate screw with a Phillips head screwdriver. Investigate the belt area to see if it is broken or has somehow slipped off. If it is broken, you can order a part from or from many of the other online parts stores.
When the belt arrives, simply slide it on in place of the broken belt, reattach the bottom plate and turn the Hoover carpet cleaner right-side up. Turn it on to test your solution.

Hoover makes terrible screaching sound when using upright.

It's most likely the bushings/bearings in the beater bar (roller). The beater bar cover is fairly easy to remove -- take it off and investigate. Could be that the roller only needs lubricating on the ends. Also, check the belt to see if it's intact or damaged.

Clean area thoroughly.

If this is not the problem, please, let me know.

Belt tension adjustment

If you are looking at the belt while the vacuum is in the upright and locked position, the belt will be loose. The idler removes tension so the brush doesn't spin while you walk away and put heat marks in the carpet. Hit the lever that allows you to move the handle low, like you are vacuuming under the bed, and the belt gets tight.

My vacuum does not have any suction, and it spits out dirt when I roll it backwards. It is an upright Hoover Elite

Trouble Shooting guide:

1. Check to make sure that your agitator still spins. (Agitator = brush). If your agitator does not spin, it could very well be a belt gone bad and means there will be no suction.

2. If belt is fine and agitator spin, your vacuum could be clogged. A clogged vacuum can be cleaned with a brush inserted into the hose of the vacuum to pull out the debris.
