Question about Hoover U5750-900 WindTunnel Bagless Upright Vacuum

Open Question

Hoover Windtunnel U5750-900 Agitator brush is weak. It turns fine if I tilt the vacuum back, but it slows to almost 1/4 speed when it touches carpet, even on the highest carpet setting. I've replaced the agitator belt twice. The brush used to turn powerfully even on the lowest (Hard Floor) setting. Ideas? I should probably lube the agitator brush ball bearings, and re-check the belt, but, other than that, I'm stumped.

    what is the part number you are using for the belt. I can verify this first. Next, check the roller when removed from the vac. it should spin freely without any drag (ie, stand it on one end and hold the top and spin it to create a barber pole pattern). if it drags then yes, clean oiut the end caps of dirt and lube bearings. One of the causes of this problem is the carpet setting used is set too low and will wear out the belt soone. under normal use, the belt should last about 1 year

How to replace power cord on Hoover Windtunnel...
Posted by SaxTeacher on Apr 15, 2008
The cord on my Hoover Windtunnel upright vacuum is damaged from having been run over while vacuuming. I purchased a replacement power cord, agitator brush, belt, and filters from the Hoover web site.
I have installed the new brush, belt, and filters. I'm ready to install the replacement cord, but I can't figure out how to access the interior part of the vacuum! I tried removing many different screws but none of them seemed to give me access to the necessary area. Any help would be appreciated!



Hello,
I would advise you to ALWAYS to FIRST UNPLUG YOUR VACUUM before beginning any service procedure.

Depending on where the cord comes out, you may want to check the owner’s manual for the exploded view of the cord area. Usually the cord comes out of the handle and there should be handle screws to release the existing cord and when you replace the cord mark the wires so that you will replace the new cord in the same manner. If it comes out of the body of the vacuum there are recessed screws that will let out into the vacuum to replace the cord. You don’t want to exceed the repairs cost to the price of what you paid for it. The decision should be yours, example: if the repairs costs are $200.00 and you paid $279.99 then @ that point you would have to decide if the repair costs are worth or do you want to pay the lower cost of repair and continue on. Just a suggestion... You may want to check with your local vac dealer. So if you need further assistance, please feel free to contact your local vacuum cleaner dealer in your area or in the yellow pages, or contact the factory phone number or website to further assist you with your questions.

SOURCE: hoover steamvac won't spray water on carpet.

Check the ank valve to make sure when you push it in that water is coming out. The reservior asm, (the tank bottom sits on this)is bad or the rod in the handle isn't pushing the reservior asm when you squeeze the trigger.

Sounds like you have a clog, which is a fairly common problem with these.

Check the air inlet immediately aft of the brushroll for clogs, then make sure the main wand and hose are also clear. If you have the machine on, check at the end of the hose for suction. This is a fairly common problem for all uprights with tools on board. Their airflow is very low, so they tend to clog up easily and then overheat the motor.

SOURCE: plugged hose on Hoover Windtunnel

you will have to remove the bottom cowling under the vaccum cleaner there are 4 phillips head screws one at each corner when you turn over the vaccum cleaner, take this off and remember how it goes back on. in the area where the hos is there will probably be a clog at that point. remove this and pull hose off and make sure it is not clogged farther up the hose, reinstall and check

SOURCE: auto brush on hoover windtunnel doesn't spin anymore

I have a Windtunnel S3765 with the same problem - and it has very little use so I'm confident it isn't wear. I find that the wheels do not raise the agitator brush sufficiently high to reduce the drag caused by excessive contact with the carpet. If I raise the front a bit the brush spins as it should. It also works if I take the housing apart and use it without ..... but this is tricky.

Unfortunately I haven't figured out a way to hold it up efficiently. I am toying with afixing something to the bottom of the housing to raise the front enough to give the brush a little more room.

How to repair windtunnel hoover agitator that will not turn


Likely a broken belt. Also check the agitator brush roll bearings (in either end under the end caps) for hair, strong, thread, etc. as this will make the brush roll harder to turn and wear/break belts prematurely. If all these check okay, then observe the tensioning roller that causes the V belt (runs from the idler pulley to the brush roller) to be sure it is swinging down when the handle is released to hold tension on the belt, causing it to rotate. These tensioning rollers can break, but often are locked into the "Bare Floor" setting without the user noticing. Slide the carpet brush roll selector (located on top, next to the floor height slide adjustment) back and forth and make certain it is all the way into the "Carpet" setting to allow the tensioning roller to engage. [Note: The tensioning roller is always retracted (in the neutral or off position) when the handle is in the upright position. You must release the handle to allow this tensioing assembly to engage.]

Agitator brush won't rotate. belt is fine, replaced v belt but it is loose. thought the old one was stretched out but new one is the same size.


The brush spins around an "axel", try removing rotator & spray wd-40 with red straw into it. See if that works, but do NOT use on carpet until dry or you will get grease stains on carpet.

Bought a new sweeper and brush ( beater bar ) does not turn. The large belt is fine and turns. The small thin belt is also fine but does not turn the brush. It is either the wrong belt or is there...


Jim, To put tension on the brush, tilt machine forward when upright, move carpet selector knob to carpet. then turn vac on. Brush will only spin when vac is tilted back to operate. brush stops when upright and on to use hand tools so the er is no danger to carpet or persons with moving roller.

Brush roller on Hoover upright stops turning


There should be a belt tensioner for the V belt, maybe it is not contacting the belt when you tilt the handle back. If this is less then 1 year old, then it is under warranty, take it in to a warranty servicer for warranty repair.

Self-Propelled WindTunnel by Hoover U6445906


· Sometimes grabs the carpet for no reason.
· Comes back too fast when I push it back.

I would advise you to ALWAYS to FIRST UNPLUG YOUR VACUUM before beginning any service procedure.
Self-Propelled WindTunnel by Hoover U6445906 Without knowing the brand name or model number you may have the height adjustment to low and the vacuum will say “bite down” on the carpet of which will make the belt burn and might leave marks on the carpet – and if you have a self-propelled vacuum it does come back fast if you because you have a transmission just like a car and you have to control the speed of the vacuum or because it may have a weak belt the vacuum will pull back easier – I really would like to know the brand name and model number so that I could accurately give a better answer . Recommended belt change for flat belt(s) are 4 to 6 months for better cleaning and one a year for a geared belt – both can stretch and lose their cleaning function
