My Hoover Wind Tunnel will not keep running. It turns itself off after about 3-4 minutes. I have checked for clogs and there are none. I replaced the filter and bag also. It also seems to be running a little louder than it used to. PLEASE HELP! I have 5 cats!!!!!! Thanks Pat

Your new machine is probably so much more efficient than your old one that its filters are clogging up very quickly. Keep cleaning the filters, all of them including the exhaust filter if fitted, and gradually you will find that the problem disappears.
