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

Suction too great, can't move vacuum

\015 The vacuum has become impossible to propel. The suction holds so strong on carpets I can't move the machine regardless of which carpet height the selector is on. I had the same problem 3 years ago and found a tiny vacuum repair shop. The guy did the repair while I watched and charged me $10. Unfortunately, he's no longer there and I can't remember what the problem was...\015

Answers :

The problem here is the height adjustment has disengaged from its action below the hood of the vac, leaving the vac in it's lowest position. This does not allow any "AIR FLOW" under the head so it just draws down into the carpet You need to remove the adjustment knob and the hood as though changing the belt and then reassemble with these components aligned to each other. Also check your belt for slippage while inside..

Hi: We ahve a Tornado CV30 vacuum. The suction does not seems to be working properly. There is no suction at the tool hose and the bag does not seem to have air moving into it. Do you think there is a clog somewhere? The roller is moving. Thank you for youre help :) Kelly Branson, Mo.

I have a Eureka Power Plus vacuum, model 4702, type A. To start off, it never really had great suction. Marginal at best. Then today I was vacuuming and smelled something burning and turned off the vacuum. At that point, smoke started pouring out from the bottom of the vacuum so I layed it on it's side and the smoke cleared but I never found the source. Is it safe to turn on again after I let it cool down or is my vacuum "shot?"

I purchased a Eureka C4910 last year and have a question that I am hoping you can answer. There are two motor actions with this vacuum, 1) the vacuum suction, and 2) the beater bar. The action of the beater bar is that motor is supposed to automatically shut off when the handle is in the complete vertical position assuming the vacuum is stationary, but then turn on when the handle is tilted toward the floor, assuming the vacuum is moving back and forth. The beater bar motor turn-on mechan

The Panasonic MC-V7515 has two belts. The local vacuum repair guy says he only has a part number for the drive belt, which is UB-9. How do I find a replacement for the other belt, the one which directly drives the beater bars? By the way, this vacuum has great suction, but otherwise is far inferior to my previous Panasonic vacuums. The cheaper models aren't a good buy--stick with the more expensive models.

Poor suction absolutely loved the machine when I first got it. I have dogs so it is getting a work out. however, the suction isn't as great as when I first got it. I have cleaned the washable filter and empty the cylinder after every vacuum. When I use the hose, the suction just isn't there. anything else I can do?

I washed it and air dried it, put it all back together ... Dyson DC14 Animal Bagless Upright Cyclonic Vacuum

Loosing suction I am loosing suction on my vacuum. I have only had it for about 6 months and cant figure out what is wrong. Can you help?

I've had my Dyson DC14 vacuum cleaner now for approximately 9 months and been very happy with my purchase. However, It is used sparingly maybe twice a week at the very most. The problem is when I try to use the item on my carpet, you have to push really hard to get it to move. It's as though the suction power is far to strong. It certainly doesn't glide as I think it should. It still picks up as usual but I cannot imagine that having to 'force' the machine to move is the normal operating procedu
