Here's a video that we've recorded to help you with this exact problem. This particular design is not a great design by Hoover, especially the belt system. The way the belts are designed, most people have to replace them at least once a year if not more frequently. This machine is a two belt system, and it's recommended that the belts replaced in conjunction rather then separately.
In this GoVacuum made video it will also show you to do basic maintenance on the roller brush which will prolong the life of the belt substantially. If this wasn't able to fix your vacuum, please feel free to use the Clarification Request feature here on Fixya.
I'm researching the noted Hoover U6630-900 Windtunnel Bagless Upright Vacuum. Please confirm that this is, indeed, the vacuum you have.
I have found a parts breakdown and am looking for a manual at this time. Please standby. :-)
yeah... it's bad.. you just need to get a new vacuum. i replaced the belt several times on mine.. and it got to the point that i had to replace it every time i used it!!
Your Hoover is stopping because it is overheating. This is a sure sign that there is a blockage somewhere. Find the blockage and clear it, and that should solve the problem.
I had same problem - the foot release pedal would not spring into place when unit was upright (but would work if you nudged in place with your foot). I installed a replacement part, and it didn't fix the problem. I cut out a small sqare of sponge and jammed it behind the flat end of the bent plastic spring on the release pedal, and it now springs back as it shoud. Hope this helps.
The belt that drives the brush roll has broken. That's why it doesn't pick up and why it doesn't pull itself forwards. Check the User Manual (download from Hoover website if necessary) for information on replacing the belt. Good luck!
Take the lower plate off of the unit and check the belt for breakage. also, if it isn't broken, are there any obstructions between the belt and housing?
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.
The part you refer to is not the HEPA filter. It's a very common misconception that that part spins - it looks like it when there's dust whirling around it. In fact, it does not spin - there are no visible moving parts.
Take all hoses off and check for blockage from top to bottom. If there is not any blockage, then check the motor, sounds as if you are not getting enough power out of the motor
There are several filters on bag-less vacuums that need to be cleaned. Dig out your owners manual or open the one below. See section 3 for filters and maintenance. If you are vacuuming a house bigger than about 1500 square feet, you should be cleaning the filters every other use. Personally, after using a bagless for a couple of months, I went back to my bagged vacuum. http://www.hoover.com/pdfs/manuals/U6630900.pdf
take the handle off 2 screws i think then open the attachment door take the screws out in you will see the switch jump the wires if it runs get a new switch
The hose that leads from the brush area to the bagless area is clogged. You will probably have to remove or partrially remove the hose to clean it out. You might get away with sucking on the hose (reverse direction) with another vacuum. If you don't find a clog in the hose, you have a SERIOUSLY clogged filter system. Of course there could be other reasons too, but try this suggestion first.
I have this same model and removal of the hose was pretty simple, by removing abour a half dozen screws. I had limited luck with the vacuum process, I pushed the clog out with a broom handle. I had 100% recovery of efficiency.
By the way, clogs are the #1 reason I find dozens of vacuum cleaners (all manufacturers) on the side of the road. I pick them up, clean them (about 10 minutes) and sell or give them away.
