Having problems with your Hoover U6437-900 / U6439-900 Windtunnel Bagged Upright Vacuum ?

How is the V-belt tension adjusted (Hoover Model U6439-900)or how do I know if the tension is correct? There seems to be a lot of "play" in the belt and I'm wondering if that is the reason the brush roll only turns as the wheels turn, regardless of the carpet height setting. And yes, the brush roll is set for carpet, not hard floor. Or is the cause of the problem something other than the V-belt? A new flat belt was installed when the machine was professionally serviced so I assume (?) that was a


Answers :

The V-Belt is not adjustable. There are two ways the belt has no tension: (1) when the handle is upright, a mechanical lever takes the drive tension off the belt, and (2) the brush roll lever setting you described. The upper handle would have to be in the floor cleaning position to check the belt, not in the storage position.

Brush Roll belt stops turning durring vacuuming on WindTunnel self-propelled, v belt is a little loose with handle down. Tensioning roll is engaged OK, but fully at the end of its travel. Replaced belts flat and v, but still stops turning even on high carpet setting when vacuuming. Carpet setting and height adjustment appears to be working OK, roll is clean and turns easily when out. Also turns easily until it engages the carpet. Self propel function works just fine.

Hoover Windtunnel U5750-900 Agitator brush is weak. It turns fine if I tilt the vacuum back, but it slows to almost 1/4 speed when it touches carpet, even on the highest carpet setting. I've replaced the agitator belt twice. The brush used to turn powerfully even on the lowest (Hard Floor) setting. Ideas? I should probably lube the agitator brush ball bearings, and re-check the belt, but, other than that, I'm stumped.

My Kirby Heritage II vacuum is not picking up dirt up out of the carpet like usual, and I have to keep setting it lower to pick anything up. I finally get it to such a low setting that it starts sucking the carpet up and makes a whirring noise, and starts smelling. Every time this happens, we find the belt has been burned. We are wondering if the brush roll inside with the brushes that pick up dirt are worn out and too short?

I have a Miele S1721 Powerhouse upright vacuum. When the belt broke I took it into the shop (because when i tried to replace the belt, the tension was so tight I couldn't get it back together!!). When I got it home I DISCOVERED THAT THE HEIGHT ADJUSTMENT DIDN'T WORK anymore. It seems like it's set really hight, because it no longer contacts and brushes the carpet. So it's now useless. I went back to the shop and the tech denied that there was anything wrong. (I didn't have the vac with me). No

I have a Filter Queen Majestic 360 and am having problems with the powerhead. There is a loud rattling noise in the powerhead, especially when I vacuum thicker carpet. I have replaced the motor, roller brush, and belt, but the rattling remains. It sounds like it is coming from the roller brush area,and when I turn the powerhead over, it rolls free and sounds fine. Any thoughts?

I have the Eureka 4870 "The Boss" Smart Vac. The beater bar began to turn constantly and can't be shut by moving the Brush Roll Contol to Bare Floor position or the machine to the upright postion. It has also eaten two new belts. A local tech says he has seen this problem whereby the free-wheel assembly that makes contact with the belt to engage the beater bar is misalgned and cannot disengage. It is usually the chassis which would mean replacement of enough parts that would not be worthwhile

Hoover WindTunnel S3765. The motor spins and the belt turns when I turn the brushes on, and the brushes will spin. The problem is that when I do this on carpet, the brushes stop spinning. As soon as I pull the "head" off the carpet, the brushes spin again. It's almost as if the vacuum suction is too great. I took the head apart and watched the motor turn the metal spindle that the belt rests on, and the belt turns as well.

Hoover Wind Tunnel 7500 Brush not Turning. I have replaced the Brush and the belt. The problem does not seem to be either to me. I believe might be a missing part. The place were the belt hooks on is a metal pole which never seems to grip the belt well. In fact it seems loose most of the time and slips on the brush, causing the belt to eventually burn up. Could there be a missing plastic or rubber piece meant to hold the belt taught  on the metal pole?

I have a Dyson all-floor model (not the ball). I recently replaced my carpet to a Frieze. Since replacing the carpet, the Dyson is extremely hard to push. It almost forms a "seal" with the carpet. Seems to work fine on Berber carpet and laminate floor. My husband has checked to make sure the brushes are working, hoses are not clogged and belts are OK. I've had it for about a year. It is virutally impossible to push on the new carpet. Any ideas?
