Roller brush on/off switch on hoover windtunnel u6401-9rm broken

We have checked both belts and even replaced the v-belt with an extra and there is no difference. the problem seems to be with the brush roll on/off switch. it seems that the v-belt should be slack when in the ''off'' or ''floor'' position and taut when in the ''on'' or ''carpet'' position. we would like to do the repair ourselves. what part(s) do we need and how do we go about the repair?

    this is clarification for the issue. it seems the roller brush switch is broken (or, according to elektek, it could be the idler assembly). the switch moves back and forth freely where before there was some resistance.
    both belts are in perfect condition. one was changed recently.

    What is your exact problem with the vac? from your description I gather that the roller does not spin This model, when in the upright position, the roller will not spin ( the v-belt will be loose) regardless of the carpet switch position. When tilted back to use, this is where the switch position determines if the v belt is taught or loose as to when it engages the roller. If you had changed the v belt when the vac was in an upright position and just turned over, then yes, the v belt will be loose. The proper way to change the carpet mode is to tilt the vac forward and move the carpet switch to on or off.

    If all of this check ok, and changing the carpet switch has no effect on turning the roller on then the switch may be broken, or the idler assembly that engages the v belt belt. Check or change the flat belt - thi drives the roller as well as your self propelled operation (should be replaced anually)

Sounds like you have a bad brush roll(48414115), take it out and see the the ends turn freely or not, if not, then replace it. Also check the the slots that the brush roll sits in to make sure they haven't melted. I am assuming that the motor is running, if not, then it may have froze up.

SOURCE: Belt Stretched on my Hoover Windtunnel Farrington upright model U6431-900

hi, In order to to replace the V belt the one that turns the brush, One must take off the bigger belt " drive belt" that goes over that hugh wheel towards the back. When a belt gets stretched they will not turn the brush very well. If you have bought replacement belts the bigger belt Drive comes 2 in a package. Then you have your little V belt that helps turn your roller brush over. Yes the belts don't last long on my hoover. For kpatr22101 When you rpelace that V belt it goes over the roller brush into a little groove on the brush and then over a plastic round wheel then you must put on that bigger drive belt that must fit over that hugh wheel towards back and smaller on in front. Yes it is hard to get on. the I hope this helps. Cindy G.

SOURCE: Brush Roll belt won't engage on WindTunnel self-propelled

When you had the brush roll off, did the ends turn freely? If not then the brush won't turn and the belt will just slip. You would have to replace the brush roll if either of the ends are frozen. Other then that you would have to remove the top cover to see if there any broken parts, there is a spring loaded asm, it has a black wheel that will push the V belt when it is in the carpet setting and the handle is in the down position, it could be jammed so the roller is stuck.

Brush won't spin on hoover wind tunnel bag less upright when on carpet, belts are fine


The belts may look fine but may be stretched and worn. Replace them. Make sure brush spins free. Idler pulley should tighten belt tension when handle is released

I ran the vacuum over throw rugs and the brush roller just stopped. I can't get the roller to work now... it won't even spin and the "brush" feature is in the ON position.


You've got a broken belt. Most Hoover Vacuums have a spare belt attached to the vacuum itself. Replacement is fairly easy and usually won't require tools. To replace your belt:
  1. Unplug the vacuum
  2. Locate clips on bottom of vacuum-Hoover uses clips that can be opened by hand.
  3. Lift up the plate that encloses the rollers
  4. Remove broken belt
  5. Remove roller from it's compartment
  6. Install replacement belt (hooking it around the motor and roller, using the roller for leverage to stretch out the belt until you have the roller in it's compartment.
  7. Replace cover
  8. Put clips back in place.

THE ROLLER WON'T GO AROUND. THE EXTRA ATTACHMENT WORK WELL, BUT THE ROLLER STOPPED GOING AROUND.


HI There,

This is definitely a problem with your belts. This Hoover Windtunnel Self-Propelled models has a poorly designed belt system that frequently goes bad. Most customers will have to replace the belt once every 8-12 months, some even more frequently than that.

There are 2 belts on this machine, and it's recommended that you replace both belts at the same time. If you just replace one of the belts, this will cause the other belt to go bad quicker.

If you don't already have the replacement belts, here are links to these belts through us:
Hoover WindTunnel Self Propelled Belt Set (38528-034 & 38528-035)

Here's a helpful video that we've recorded that shows you step by step on how to replace these belts, as well as how to do the basic maintenance on the roller brush to prolong the life of the belts as long as possible.

How To Replace the belts on a Hoover Windtunnel Self-Propelled:

Please be sure to rate this repair helpful, or leave feedback if this video helped you fix the problem. If you're still having problems, please just use the comment field on the repair page and leave a little more specific information on what happened when you inspected the belts, and I'll be more then happy to do some further more advanced diagnosing for you.

By rating the repairs helpful, and leaving feedback, this ensures that Fixya experts continue to leave free repair solutions rather then just leaving premium answers, or repairs that customers pay to have answered. This is also really appreciated.

Describe how to replace belt on hoover windtunnel bagless


If you turn the vacuum so the bottom is facing up you will see the base plate that covers the roller brush. There will be four screws (usually phillips head), remove the screws and the base plate will lift off. You now have access to the roller brush and belt. Lift the roller brush up and remove the old belt. Place one end of the new belt over the motor shaft and the other end over the roller brush and put the roller brush back in place. Now simply replace the base plate and you're done! This models requires Hoover belt # 38528033 (single) or Hoover belt #40201160 (2 pack). You can get this belt at www.vacbelts.com.

The belt on my hoover will not stay on. It falls


Okay. I would suggest that you have a problem with your roller brush. If the roller becomes clogged with hair/debris, the bearings will sieze, and sometimes even melt the plastic. the roller then has a difficult time turning and will break the belt. If the belt is slipping off, I would suggest that you either have a worn belt, the wrong belt, Or, your "windtunnel" (the half cylindrical insert the roller sets in) is missing. this insert has a "belt guide" that keeps your belt aligned. hope this helps!!!

Flat belt on Hoover Windtunnel requires to be replaced regularly


No it is not normal. The brush roll may be bad causing extra stress on the belt. The other option is the belt is installed incorrectly. I believe this model has a brush on/off option and the belt must be correctly installed around both the motor shaft and the shaft for that brush on/off switch.

Hoover WindTunnel Self-Propelled V Belt


when you released the end to slide the new belt on it allows the tension roller to slide into the wrong position. Remove the top so that you can see the roller, at the left side of the roller mechanism there is a screw, loosen it enough to allow the roller to return to the correct position.
good luck

You could try contacting Hoover for parts availability. If it's and older WindTunnel and Hoover no longer has the part, try eBay.
