Hoover u5720-900 quits running and restarts again after some time
I use my vacuum and after about 3 or 4 minutes it just shuts off. After about 10 minutes it will work again but shuts down after another couple minutes. I cleaned everything thoroughly and made no difference. Please help I have to repair shop were I am. thanks

There is one more filter under where the collection tank & Hepa filter sits -- there is one screw that holds the cover down - remove that filter and clean it that will help. I also find I need to vacuum the hepa filter as well- it is too expensive to replace all the time. The Hepa filter can be placed inside a plastic bag and shaken really good to get the dust off of it

There is a thermal reset inside the motor that shuts it off. There may be a clog.somewhere or something restricting the airflow, it could be clogged filters. If there are no clogs or restrictions it is possible the thermal reset is bad in which case you will have to replace the motor.
It's possible the thermal reset is defective. It shuts the motor off if it gets hot. Remove the bag door and take the bag off, remove both filters and then turn the vacuum on, just leave it sit there with the motor running. This eliminates the bag or filters causing any airflow resistance. If it still shuts off after a few minutes it's likely the thermal reset is bad. Some vacuums have an external thermal reset button which can be replaced if necessary but on your model it is built into the motor and you must replace the motor. If the motor runs fine put the bag and the filter under the bag back in - (make sure the filter is clean and not restricting airflow) put the bag cover on then turn it on again. If it overheats and shuts off then you may have a clog on there somewhere restricting the airflow. If so check the power nozzle area, the hose coming from the power nozzle, the extension hose and wands for clogs or restrictions.
Do you have suction through the tools? Does it look like it picks up when it runs? The machine could be clogged and that would cause the problem, but unfortunately the sensor that shuts the machine off could be bad if the machine isnt clogged. Its not easy to get to it, I'd take it to a repair shop.
I would say check inside the plug and make sure the connections are tight. If the vacume runs fine on the other socket outlet then it will bw a faulty socket which cuts your hoover out. Can buy a new socket frount from diy stores for about 2-3 pounds. If the hoover also cuts out on the other sochet it will be a temperature cut out device on your hoover. If this is the case empty the bag and give it a good clean and get rid of any accumalation of dust/dirt
yes i think i can help. all new hoovers have a thermal motor senser that turns the motor off wen it heats up to a certain point mine hade the same problem so i toke it apart and the bering in the motor was worn and heating up and tripping the senser if u have wd40 put some on the bering and be shure to wipe excess wd40 off so it doesnt get in the wires.
