Question about Hoover U5780-900 Windtunnel Cyclonic Bagless UprightVacuum

3 Answers

My Hoover Windtunnel cuts off after using it for a few minutes. After an hour or so, I can turn it back on again. This keeps happening every time I use it. This is my third one. I have taken the other two back to Target for the same problem and they have exchanged them.

    Thanks Mav. I actually figured this out some time ago. I almost threw the thing away until I found the small filter at the top.

Yes this machine has a thermal protector in it to shut off the machine if it gets to hot, this is normal. if there is no clogs in the hoses or in the machine then you will need to wash the filter at the top of the machine. you will have to remove the dirt cup and at the top you should see a half moon orange, well inside of this piece is the washable filter, clean and let it dry completly before putting back into machine. if this gets dirty and has not been cleaned, you can lose alot of suction. in some cases if this filter is not cleaned it can cause the machine to overheat so bad that it can damage the motor.

    if you have the machine in front of you, take out the dirt cup. once you take out the dirt cup look on the top, but inside the machine. you should see a half moon or a gray piece that can release itself from the machine. inside of this part it a washable filter. hope this helps alittle bit better. write me back if your still having problems, also if you do please provide me with your model num. also thanks

There is a filter located above the pop-out canister. First remove the canister. There are directions on a sticker (inside the canister area) that you can see once the canister is removed. The filter pops out. Clean the foam insert as well as the other part (you should be able to see through the mesh material). Our vac ran like new afterwards. It had a ton more suction.

Hoover U5780-900 Windtunnel a month 1/2 old just started stopping when it is running and wont turn back on for a few hours why?


The motor has a thermal protection sensor on it. So your motor may be going bad, it is pulling to many amps for some reason, could be a clog somewhere or a bad bearing in the motor.

Hoove Cyclonic Bagless vacuum shuts off after only a few minutes


The motor has a protective overload cutout device to stop it from over heating - this can be caused by a blockage of some sort in the hose or brushroll compartment or blocked filters.
After checking the above and it still cuts out, take it back under gurantee

Stops after a few minutes


Its overheating, so the TOC (thermal overload cutout device) is cutting the power to the motor to protect it.
Thats why it works when it has cooled down.
Check for blockages and make sure the filters are clean, if it still happens take to an approved engineer to check the TOC

Might be that its not exausting enough heat & stutting its self down..

Try cleaning all the filters & the hepa filter..
This will increase air flow & maybe fix the issue..
