Hoover Wind Tunnel U5720-950

I was sucking up kitty litter and the vacuum stopped working. After letting the vacuum cool for an hour, I tried to run it and it quit after 3 to 5 seconds with a nasty burning smell.

I tried to take it apart to clean the motor out but can't figure out how to get to the motor.

    Thanks ol_lonely.



    The litter box is halfway down to the basement (nice and private for the cats, no smell for us humans). The stairs are carpeted and sometimes the cats track a little of the litter onto the stairs. I was only vacuuming the few dry bits on the carpet, not huge wet amounts.



    My vacuum is a Hoover Wind Tunnel Bagless Model U5720-950 and I never thought about a quarter cup (maximum) of dry litter could have got through 3 filters to the motor.



    I would still like to try to get to the motor so I can try to repair or replace it on my own. Any suggestions?



    Thanks for your help.

Be sure it has a new bag and fillter, or try running it on a clean surface with the door off. if it still has a burn smell and only runs a few seconds the motor is probably bad. expensive and difficult to access. kitty litter has moisture in it and the vac motor is strong enough to pull the moisture out and draw it through the motor which will damage the commutator. kitty litter (and plaster dust) are stone dust composed and will pass some material through filters in to motors. for such jobs you should use a shop vac style machine , since they have a bypass motor that doesn't pass material through it.

    you must remove nozzle base from upright portion. you then need to separate front and back halves at lower end. the motor shaft is where the belt attaches. the motor is inside the lower end of vac and is usually packed in foam and and rubber gaskets. when accessed, remove carefully and check carbon brushes. this is about the only part of motor that is serviceable.

My hoover wind tunnel just quit while vacuuming. It is dead??? Two years old used about every other week? Any suggestions?


Some Wind Tunnels by Hoover have a poor design in the switch on the handle. Sometimes the switch does not turn on all the way and will stop running. Other times you can't turn the unit off.

Reset button on hoover wind tunnel


Hi there! There is no reset button on the cleaner. The vacuum has a thermal protector sensor that will shut the vacuum off when the motor reaches a certain temperature. This is usually caused by a clog or filter that needs to be cleaned or replaced. Be sure to check the hoses for clogs and clean and replace any filters if needed. The vacuum will turn back on when it cools off, this can take up to an hour. Good luck!

Hi My Hoover wind tunnel cyclonic stopped working when i was using it. I tried different plug even then it doesnt work . What to do??


If the motor stopped running, it most likely did because it was not being cooled, becuause something was stopping up the air flow. If you have cleaned the secondary filter out and it still stops while running, then remove the exhaust filter cartridge and try it then. If it does not stop running now, then the problem is the previous models like this had a foam filter as the exhaust filter, not a heppa cartridge filter. You will not hurt the machine by running it without the heppa cartridge. Cut a foam filter to fit to replace it. I do not think Hoover knows this yet.

I have a customer working on this problem today (Sept 2010) I have repaired machines for 30 years. This filter is meant to just catch the tiny particles from getting back into the air. However, it worked fine on the previous machines with the foam filter here instead of this Heppa cartridge.

How do you change the Hoover wind tunnel belts?


If you turn the vacuum over there will be (4) screws that hold on the base cover for the roller brush. Remove the screws and the cover and you can get to the belt(s). You can get replacement belts here:

Where is reset button on Hoover Wind Tunnel vacuum?


Hello my good friend, this cleaner doesn't have a reset button or anything, it resets by itself after cooling down, it takes about 30 minutes to cools down.

Did you check down by the brush roll for a clog in the dirt inlet. And is the brush roll turning freely, if it is being lugged down, it can cause the motor to overheat and the thermo protector will caught it off, until the motor cools down. But if both are ok, then maybe the motor protector needs to replaced, it is prematurely tripping.

A clog or partial clog is what causes the motor to overheat, then a thermo protector will cut off and the motor will stop until it cools down. So either you do have a clog, in the hose or down by the brush roll. If they are clear, and the filters are clean, then maybe the thermo protector is bad and needs to be replaced.

Hoover doesn't suck well


Did you check the inlet from the bottom? Take the bottom plate off, make sure that the tube(inlet)is free of any clogs. Also if the belt is stretched, then it won't drive the brush roll like it should, replace it part #38528033.
