My Hoover WindTunnel vacuum cleaner has a problem. The brush will not
roll on carpet but will roll on bare floor. You can smell the burning
rubber of the belt.
I replaced the original belt once and now the second belt is doing the
same thing. This is the way it is set up: The roller has a smaller
belt that attaches to an internal roller's groove. The internal roller
has a plastic wheel where a second larger belt turns it. This belt is
attached to motor's shaft.
The second belt is the problem child. It is getting worn down at the
motor shaft and stinking up the place. Now whether the belt is the
problem or the other roller, I don't know. Is there anything else I
can do before I'm forced to take it somewhere to get it fixed?
