Ya but .... In the central vac unit the
air flow over or through the motor is
what cools the motor.  The "moronic
device" would solve that problem by
providing an inlet for air, when the
lines are plugged.  I'm not sure I agree
with the vendor's picture of the house
and garage burning down.  The motor
thermal protector should prevent that.
That all said, I had a central vac in my
previous house for 36 years and can
count on one hand the number of times
the thing actually plugged up.  Robert,
if it is plugging in the hose, there
might be something wrong in the hose
causing it, like a tear which would
catch fuzz going by.  If the plug is
occurring in the wall piping, again
there might be a reason.  I remember my
2 year old dumping some small wooden
blocks in the inlet near his room.  They
went through the pipe with no problem
but couldn't make it through a Tee.  It
was about 1" x 1" x 3".  This caused a
place for new dirt to catch and
eventually plug up.
