Question about Hoover U6437-900 / U6439-900 Windtunnel Bagged Upright Vacuum

1 Answer

Beater Bar The "Beater Bar" or roller with brushes on it, is not spinning, therefore not picking up. I cannot locate my manual and need to know if it is belt driven and how to get at the belt to identify the size and purchase and install a new belt. Thank you for any assistance.

Re: Beater Bar

Take off the bottom plate, then you can get to the brush roll and belt, on the model number plate, the number of the belt is on that, it is also on the belt if you can still make it out.

Beater bar only spins when vacuum is locked & upright.

Your belt is probably stretched and can't turn the brush when it's on the floor. Replace the belt at least twice per year.

I replaced my Bissell vacuum cleaner belt with a Bissell belt. I ordered it from them so I know it's the right one. I replaced it and the roller won't spin and the belt smells like it burning.


You will need to unplug the vacuum from the wall, lay it down so you can see the bottom of the vacuum head and remove the bottom plate (foot plate) Probably philllips head screws. pull up on the roller (called the beater bar). The beater bar will come straight up. Disconnect the belt and check the fittings at the ends of the beater bar... I'll bet that they don't spin easily (The fittings have roller bearings in them, and the roller bearings get gunked up with hair, carpet fibers and dirt). Pull the end fittings off of the roller and remove all of the hair and carpet fibers off of the end of the beater bar and the fittings and out of the bearings. Check to make sure that the roller bearings spin freely. If they do not spin freely, put some rubbing alcohol in the bearing (you can pour it onto the bearing and spin the bearing manually until it spins freely, or you can use a spray bottle with alcohol in it as I do. Once the bearing spin freely, dry them out so no alcohol remains in the bearing, then a drop or two of light machine oil (3 in 1 oil will do) in each bearing and spin the bearing again to distribute the oil. Now would be a good time to check for any clogs in the vacuum head where the hose connects, and check the hose for clogs. Reassemble the beater bar and reinstall it in the vacuum with a new belt, reinstall the foot plate.

Your machine should run like new.

Roller brush will not rotate. Brush motor and associated shaft are spinning. Belt has been replaced. Appears that the Brush Bar is frozen..... Is there a bearing in the roller brush that is frozen? ...

More than likely there is gunk underneath the endcaps. In the small airdriven attachment those end caps come off. It's likely true of the beater brush underneath too.

The brush may be spinning, but you probably need to replace the belt2_bing.gif because it is stretched. It is probably slipping on the beater bar..

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.

Beater brush won't spin but belt is intact and ok. Brush is clean and spins freely by hand.

For your beater brush to spin, you have to meet two conditions:
1) the vacuum cleaner has to be reclined (put your foot on the front and pull back on the handle).
2) The clutch actuator (the dial where you switch between BEAR FLOORS and CARPETS needs to be set to CARPETS).

If the brushbar/beater bar still doesn't spin after that, call the Dyson helpline, they will assist you. If you are saying that the brushbar isn't spinning because it is not picking up any dirt, you may have a loose internal hose, a blockage in the machine or the bristles on the brushbar are worn. Call the Dyson helpline for assistance.

Dyson vacuum cleaner-brush bar is frozen

Hi If your Dyson has a brush protection design - i.e. roller bar on the top of the hood on the left hand side then the DYson can't be repaired by you- serviceman or professional care can replace it.
However if the Dyson doesn't have the roller bar on top of the hood, flip the machine over so that the beater brush is facing upwards, locate three/four screw heads that can be undone with a coin and remove the sole plate assembly. This should give you a clean view of the brush bar, drive belt and dirt channel. Ensure everything is clean espcially if the brush bar has lots of hair or threads tightly corded around. Then locate the drive belt and check to see if it has snapped. Grasp the beater bar gently upwards and the belt and brush can then be removed. Fit a new belt on carefully and check the tension as it will be tight.

In Carpet setting, the vacuum brush does not spin

I put 3 turns of electrical tape around the area of the beater bar that meets the vacuum belt. This solved the problem short of replacing the beater bar.

Beater bar does not work dyson DC07

If the beater bar does not spin freely, and the belt still seems to be in place, then you may not need a new clutch, but you may need to reset the clutch.  This is done very simply by keeping the beater bar section of the vacuum flat on the floor and reclining the handle all the way to the floor so the entire vacuum lays flat. There is a mechanism in the vacuum which resets the clutch. You will probably not hear anything when the clutch resets.  I sat on the phone for an hour and a half to hear this simple technique is built into the vacuum, but excluded from all instructions and website customer service information.
