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

The windtunnel vacuum has suction but does not pick up the dirt. I'm puzzled as to what might be the problem. Help!


Answers :

The problem is that the belts are stretched and worn and slip instead of turn the brush when it is put against the resistance of the carpet. You simply need to replace the belts. Here are the (2) belts you need and the manual with instructions:

I recently ( approx. 2-3 months ago ) purchased a dirt devil. Now it is not picking up properly. When I push vacuum forward it picks dirt up a little bit, when I pull it back all the dirt falls out of the bottom. I replaced the filter today and it has not solved my problem. I dont know where my warranty is. Can you please help me?

I have a power drive baggless vacuum cleaner...it runs well, but suddenly it seems to have lost most of the suction coming through the hose and floor area. When I remove the dirt container, the suction below it seems strong. I have had it to repair twice--they have tuned it up and replaced all filters and belt. It still does not pick up well when I vacuum or use the hose. Can you help ?

It has no suction. It was fine yesterday. I washed the dirt container and the filter, let it dry and put it back in the vacuum. Today my vacuum isnt picking up any dirt and has no suction. When I took the hose out of the back, it started blowing dust and dirt out but still no suction.

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!

I have a Eureka Upright vacuum (4800 Series). When I try to start it by turning the switch on, it wont. For few days, I was able to get around this problem by repeatedly turning the switch on and off until it turned on but that does not work any more. Could it be something related to the switch it self or the power cable. My wife mentioned that one of my kids might have pulled the power cable too hard (at the back of the vacuum). Any help to solve this problem will be very much appreciated. Tha

No suction vacuum won't pick up -- I've checked the bag, hose...and it seems to have no sucking power. The internal hose may be jammed (I vacuumed up a lot of shredded paper), but nothing as far as I can stick in fingers in.
