Hoover Mach 5 sweeper

Hey all...

Had this same problem with my Mach 6 (same as Mach 5)

It would shut off after 15 min of use. What is happening is the secondary filters, HEPA and the canister all need to be cleaned. This is vital. What the vacuum repair people are keeping from you is that tidbit of wisdom. This particular vacuum is picky about airflow. Pull the canister, and on the body of the vacuum on top of where the canister sits are the secondary filters. There should be a sticker explaining how to remove them. Clean them throuougly, mine was filthy. Make sure you clean the canister by unlocking it and cleaning out the micro holes and the cone end. Mine was completely plugged. Now brush the dirty side of the HEPA filter with the combo tool. Let the secondary filters dry completely (you can blow dry them on cold) Re-install everything, and the vacuum will run like brand new. I vacuumed the whole house after I completed this maintainence and it works like a champ. Don't return this vac until you clean it completely.

i had the same problem and fixed it using the above instructions.

i overlooked the second filter. it's inside the machine, up above the area where you took the dust canister out.

exactly as you said, it felt brand new.

thank you for your solution

Yah the thermal coupler is right next to the flux capacitor....

I washed both filters using some mild dish washing liquid and let them dry thoroughly. Before you use water to clean them make sure you "beat" the worst of the dust out of them first by gently tapping them on a hard surface OUTSIDE your home as they are very dusty. (stand up-wind if you are smart ;) ) Don't be afraid to squeeze the sponge-like filter until the water comes out clean and forcing some water through the other part of the filter as well. Just don't be too rough, and do it by hand, I would not recommend running it through a washing machine! This is VERY easy to do and should probably be addressed every 6 months or, not when your vacuum starts shutting down on its own!

Your concerns about the "shutting off" while in use is simply due to the "overheat sensor" that this model uses. It's just a safety thing. Wait about 15 minutes till the motor cools down and it will work just fine.

There is sometimes a thermal coupler inside the machine.

And what is a flux capacitor ? and where are these located ?
is there a reset button on this machine ?

Same problem with my Hoover Mach 5 fusion sweeper.

If you're looking for help from a vacuum repair place, forget it!
They are protecting their business. Everyone I called knew the problem and said its a simple fix, but would not say another word unless I brought the unit to them to fix.

This vacuum is awful. Mine constantly shuts off after a few minutes of vacuuming. I have another vacuum that works just fine for hours! This one is ridiculous as I can't even get finished with a room before it cuts off.
