Hi, That is what was happening to my Windtunnel. Until I looked at the little round disk "plastic". there was a crack in it and this puts pressure onto that V belt to make the brush spin. I have a replacement idler arm assy unit which has to be replaced. I hope this helps Cindy G.

Hello there! If you have replaced the belt and it is still slipping off, you may be not have the right belt for your vacuum. This unit takes a flat belt and a v-belt. Make sure you are replacing the belts with Genuine Hoover Parts. I have included the links below where you may go to order the belts specific to your cleaner.

Belt will not stay on hoover windtunnel s3765


The Hoover Windtunnel™ Self-Propelled models have two belts, a flat belt and the V-Belt. This V-Belt is the one that drives the Brush Roller. After about three months, most belts stretch out causing them to slip. This means the brushroll turns slower or not at all and the self-propelled becomes increasingly harder to push. It is recommended that both belts should be changed at the same time.

Hoover wind tunnel upright self propelled. U6473-900. Brush does not work. Heard it was a 'brush controller' problem and can be fixed. Please tell me how.


Most likely the flat belt has stretched enough so as to not turn the pulley that in turn turns the brush roll using a V belt. Also there is a small idler wheel, if hook up, then it won't engage the V belt.

Self-Propelled WindTunnel by Hoover U6445906


· Sometimes grabs the carpet for no reason.
· Comes back too fast when I push it back.

I would advise you to ALWAYS to FIRST UNPLUG YOUR VACUUM before beginning any service procedure.
Self-Propelled WindTunnel by Hoover U6445906 Without knowing the brand name or model number you may have the height adjustment to low and the vacuum will say “bite down” on the carpet of which will make the belt burn and might leave marks on the carpet – and if you have a self-propelled vacuum it does come back fast if you because you have a transmission just like a car and you have to control the speed of the vacuum or because it may have a weak belt the vacuum will pull back easier – I really would like to know the brand name and model number so that I could accurately give a better answer . Recommended belt change for flat belt(s) are 4 to 6 months for better cleaning and one a year for a geared belt – both can stretch and lose their cleaning function

Replace the belt


Take off the bottom plate, put the new belt on the motor shaft first, then stretch it to go over the pulley, it is hard, but it will stretch to go over it.

Hoover Self Propelled Wind Tunnel Turbo Powered 7600 The thin belt too loose


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.
