These cleaners operate on a clean air principle, i.e., where
the dirty air enters the bag or dirt receptacle before it goes
past the motor area. Since the same air is used to cool the
motor, it is extremely important that it be filtered ade-
quately to prevent dirt and dust from getting into the motor
and/or back into the room.
Basic operation of the clean air system in these units is
illustrated in Figure 2 on page 2.
Air fl0w in the WindTunnel is shown in Figure 2A on
page 2.

Secondary filters are located behind a grill in the bottom of the
bag cavity Figure 4.
They can be washed and reinstalled when completely dry or
replaced with new ones.
Final filters are located on the side of the bag housing Figure 5.
They too are washable and/or replaceable, and made in 1, 2 or 3
layers.
Nozzle height is adjusted on the front of the unit and ranges from
high, for very deep pile carpet, to bare floor on the lowest setting
Figure 6.

An Embedded Dirt _nder TM (F_DF) feature is on some models. The
conllOl circuit for this feature is directly wired and does not require a
battery.
Red and green lights (A in Figure 7) signal the user that the system is
working. The red light comes on when the cleaner is first energized
then goes off and the green one comes on to let the user know when to
begin cleaning. While cleaning, a red light indicates that embedded
dirt is being removed from the carpet. When the light turns green the
carpet is clean.
A sensitivity switch near the light allows the user to increase or
decrease the units sensitivity to dirt (B in Figure 8). "Hi"
increases sensitivity, "Reg" decreases it.
