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

No suction I have new belts. Everything is clean. No clogs. When I turn it on it smells like rubber , the brush doesnt spin. Everything seems to be free flowing.. Roller brush isnt stuck on the ends. Took off hose to make sure no clogs anywhere. There is not even suction thru the hose with the handle in upright position.


Answers :

Generally, the problem is that the belt is not running the brushes.  This is caused by one of the following:\015\012\015\012
    \015\012
  • beater brush is jammed.  This is either an object stuck in the brush or immediately behind it in the housing or the bearings are gummed up with floor dirt
  • \015\012
  • the belt is broken and rubbing against the motor shaft
  • \015\012
  • the plate holding the beater brush has a part broken off which is causing the beater to jam
\015\012Clogs are not the problem here.  Inspect and resolve the above.  Use a new belt.  Never reuse this one.
Ok...with the vacuum on and the hose in your hand checking for suction, try pushing the cover that is over the bag against the unit,,,sometimes there is a leak and it doesnt give any suction...

No Suction I get great suction in the hose, but when I plug the hose back into the unit, there is no suction and the air flow indicator line goes completely red. I've changed the bag and filters. I took the small panel off the back and made sure there is no clog, and took the hose off to make sure there was no clog there. Still no suction. Please help.

I have a DC07 and the brush wasn't rotating and I had no suction at the brush but perfect suction through the hose. I noticed a large build up of dog hair around the brush so I took off the cover plate and removed all the hair, cleaned inside the floor/brush housing and cleaned out the hose. I also cleaned the filter and removed the other air access cover and made sure that they were clear. I put everything back and the brush still doesn't turn and there is still no suction through the bottom

Poor suction The actual sweeper seems to work ok, but the hose attachment has some suction but not enough to pick up things I think it should and not enough to make the power brush spin. I've checked everywhere I can for clogs, but I can't see anything. And there doesn't seem to be any way to check to hose itself for clogs. I've cleaned out the container and the filters, but there's still a problem.


Check the inlet down by the brush roll, make sure it is open, if it is then the hose itself must have a clog. If the hose comes off, drop something like a marble in one end and see it it comes out the other end, if it doesn't then you have a clog. ...

Hoover Windtunnel T-Series UH20700 9 mos old. Keeps clogging in hose just above the beater brush assembly. I think it clogs because the suction is too weak to pull much through. Primary filter is clean and HEPA filter is replaced. Even when everything is unclogged, suction is weak compared to another unit (same model) that a friend has. Any ideas?

I took the cover off the brush so I could cut off all the hair that was wrapped around it (vacuum was working fine, I just noticed the hair). I pulled the brush/spinner thing off one side, cleaned everything, popped it back in where it belonged, and tried to make sure the belt was in the proper alignment. However, when I turned the vacuum on, it makes a horrible noise like I'm sucking up rocks. What have I done wrong in putting it back together? It seemed simple...

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?

My Dyson DC 14 is making the horrible "ratcheting"sound only when the brush is engaged on the carpet setting. I have cleaned the brush, so there are no obstructions, the canister is empty and properly on the unit. I checked to make sure all of the "traps" and hoses are clear of obstructions, the belt is on the brush securely and moves freely, the brush itself spins freely, but there is still the "ratcheting" noise. Any other suggestions?


Our DC33 was making the same ratcheting sound immediately upon placing the cleaner/brush head on the carpet. We carefully pulled the beater/brush bar out of the vacuum. Once removed, we pulled the black plastic end off of the center rod. We discovere ... Dyson DC14 Animal Bagless Upright Cyclonic Vacuum

Lost suction my DCO7 lost suction in the hose I started taking it apart and cleaning it and looking for clogs (probably more than I should have) and when I put it back together it has awesome suction in the hose but no suction in the base. It just pulls the pine needles up (christmas tree) but they never appear in the "bag" compartment and when I look they are just all gathered in a clump in the bottom by the brush.

When I flip the switch on my sebo x1 upright, a red light comes to the brush and bag icons. However, I cleaned out the hose and checked to make sure there is no obstruction from the brush to the hose also, or from the hose to the bag. It is clear that juice is coming to the vacuum, but there is no sign of life except the two red lights.

The brush wouldn't work when the selector switch was in carpet mode. Took the power head apart and removed the motor. Everything o.k. in the power head. Checked and found that the neutural wire had pulled out of the connector, the connector was never crimped at the factory. What a day! Took 2 hours and a large pizza to get it done. Neutral wire was in the hose just below the handle. Reconnected the wire and crimped it, put everything back together. It works!!!!

I replaced the belt on my Dirt Devil Featherlite Bagless Vacuum and the brush roller rubs and makes a very loud noise when turned on. I have gone exactly by the manual instructions and made sure the belt and end caps were on correctly, but the bristles still rub the back and it makes a very loud noise. Without the brush roller in the vacuum, it sounds and runs normal. What could the problem be?

Poor Suction Heya! So I just picked up a used Dyson, but when I vacuum with it, the suction is pretty weak and it spits all kinds of stuff out the back and into my feet. When I pull the hose I have good suction, but in regular mode it hardly picks up anything. The brushes are spinning, and it eventually will clean an area if I go over it again and again. Maybe a clog somewhere? Please tell me that Dysons have better suction than my $50 Dirt Devil! Thanks!
