Having problems with your Hoover U6630-900 WindTunnel Bagless Upright Vacuum ?

I have full suction with the hose and when the brush is off of the vacuum. However, in the vacuuming position, there isn't enough suction to pick anything up. I checked for clogs and cleaned all the filters.


Answers :

So I have exactly the opposite problem, it sucks in floor mode but the hand held has zero suction. My daughter and i just spent the last hour disassembling and diagnosing and found this: The way the suction tube is configured, you have two places to **** from, the floor and the hand held hose. If you look at the back of the machine, you can see the "y" where the two hoses join. just behind the beater bar there is a blast gate that closes when you stand the machine upright. This closes the blast gate and directs full sution to the hand hose. In floor mode as the handle tips back, a follower wheel and spring move the blast gate to open. THIS IS THE IMPORTANT PART...if the hose is not docked, there is a second place for the suction to go and you will get no suction at the floor. In my case, the center post where the spring mounts is broken and the blast gate flap does not close, so the hand hose gets no suction because it is like a straw with a hole in it, the air will seek the least resistance. In your case you either have not returned the hose to the docking port or your blast gate is stuck in the closed position. To check this remove the two screws and clamp that secure the lower hose to the suction manifold. Pull the hose stright an look inside to see if the blast gate is open or closed. Use the release pedal to cycle the machine between upright and floor mode and you should see the blast gate open and close. If you don't, well that's a whole other story. I'm off to see if I can find a replacement part at repairclinic.com. If not I will have to get some polyester epoxy and fix it myself.
Check the belt it might be so stretched that when the brushroll comes in contact with the carpet the belt just slips

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. ...

** suction The best way to describe it is that when I was vacuuming I could see dust clouds at the front of the vacuum where the light is swirling around in the air. It was like it was blowing dust around instead of picking it up. I checked the tubing and found that it was clogged with some paper and hair ***** etc.... So I cleaned it out and tried it again and it still was not picking up properly. I had my husband take all the tubing apart to check for other clogging and there was none. When I

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!

My vac has lost suction. When I vacuum it picks up very little, but when I remove the wand hose it has good suction. We have cleaned both filters, checked for blockage in all hoses & cleaned the beater bar brush. All to no avail. Is it the motor? Or is there a blockage deep in the vac somewhere? We're debating repair versus buying a new one. Hope you can help. Thanks.

How to disassemble the brush to empty anything that might be stuck inside of the brush? The motor seems to be overheating, all belts have been checked, all airways are clear and the filter is clean. The vacuum is vibrating and releasing a burning smell, but still sucking up dirt. There is nothing stuck on the outside of the brush, but is there a way to check inside of it to see if that is where a clog is occuring?


If there's a burning smell and the belts are fine, the problem is going to be hot wires causing the insulation to melt, or the motor going bad. Discontinue use and have it checked at a repair shop. ... Bissell 6594 PowerForce Bagless Upright Vacuum

Oreck XL21 just will not work at all any more. Beater is clean - belt is fine. Fresh bag - inflates. Took the thing apart - checked for blockages at intake, bag entry, and the tube. It just doesn't vacuum anything. No suction at all for anything stronger than air. I'd say it doesn't ****, but that would be ironic. Are these known for just "quitting" after a while? We take it in for maintenance as recommended to replace filters, etc. Is there some miracle trick to make it work or sho
