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

No suction hello, there was a rubber smell then no suction. i'm thinking it needs a new belt but don't know how to remove the cover to replace. is it a complicated procedure. is there a diagram available? don't have any info here. thanks, leslie


Answers :

Flip the machine upside down and remove the four screws from the baseplate. Replacement should be fairly self-explanatory from there. If it's a self-propel model, note that the v-belt in the front WILL look loose normally, so it does not usually require replacement.
\015\012If you have a self propelled model, the belt you need ends in 035, if it's non self propelled it ends in 033.
\015\012Contact me if you need more assistance in changing the belt.

My versatility electrolux vacuum is 2 years old and it has lost its suction, i have replaced the filters and checked every hosing area i have access to, it seems to all be clear. I dont know what else to do, it has a higher pitched whinnig sound when it is on


It sounds like the fan blades have worn away until there's basically no air resistance, thus no air flow/suction. The whine is created by the motor turning at a higher speed due to lack of resistance. \015\012The fan wasn't covered by the wa ... Electrolux Vacuums

No suction I just replaced the bag, and normally after this I have a lot of suction. Now that I have changed the bag I have less suction that I had before. Not even enough to picj up dog hair. I snaked he hose and checked all of the connections. It seems to have an air leak but no amount of tape will fix this. I cleaned the filer as well with warm water and dried it and re installed but still absolutely no suction. I am ready to throw it out! Any suggestions would be appreciated

Poor suction...continued Wow, thanks for answering so quickly! To answer your question, yes, there is suction at the screen, but it is very weak. I keep that screen clean. As a side note, I noticed that when I remove the top clear plastic cover (that would be part # 37 on the diagram, as far as I can tell) there is decent suction coming from the intake there--part 36? 30? it's hard to tell. But with the cover on, I feel no suction (from where it sucks up the water directly from the carpet),


Wish I had it in my shop, it is hard to figure your problem. I do know that you must have something out of place and you may have to take it apart to find it. You may feel some suction there at the top of the clear nozzle, but maybe it isn't strong ... Hoover F6212-900 / F6215-900 SteamVac Agility Upright Vacuum

There is either a blockage or a pipe is open somewhere. You should check the system at the wall valve without the hose to determine if the pipes are blocked or if perhaps the hose is plugged. If one of the wall valves is damaged or open, this will af ... Vacuums
