I'm really confused.


What little experience that I have had with contemporary upright vacs, if the cleaner is latched in the upright position, the brush roll stops spinning, in order to protect the carpet.  I picked up a used Windtunnel to add to the collection, as it was made in Ohio (I owned a Windtunnel many years ago, but as it didn't care much for the berber carpeting in my old house, I gave the machine to a friend in need who ended up trashing the machine...but that's another story), and found that this machine, while according to the graphics on the label "when handle is up, brush roll is off," with the handle latched in the upright position,  the brush roll continues to spin, except when the machine is on carpeting, and the brush roll stops.  Tilt the machine back, while still in the upright position, and the brushroll begins to spin. This doesn't seem right to me, that the brush roll stops due to the resistance of the brush against the carpet. 


In normal vacuuming, the brush roll works fine, and does not bog down as if the belt is old and stretched beyond its life expectancy.


Any thoughts as to what might be wrong?


Thanks loads,

Hi Joe
I have this problem with the Vax Mach Air - based on the Hoover Windtunnel Air - and if it uses existing floor head design like your older model then the reason the brush roll still spins when the machine is tilted is because there may be a button on the front of the floor head that gets pushed in whenever the base of the main dust bin meets the floor head when the vacuum is put back into the upright position/left standing. When the vacuum is tilted, the mechanism will pop up because the vacuum doesn't actually lock down to the upright position when tilted but raises slightly. Hope all of that makes sense!

It is an issue that I noticed straight away with my Mach Air.

Is it a self-propelled model?

If so, your belts may need to be replaced. Check your V belt and flat belt. A woman from work had me look at her Self Propelled Windtunnel the brush would stop when it hit the carpet, like yours. I replaced both belts and it ran like new.

Below is a link to the manual.
