Embedded DirtFINDER
TM
feature
(some models only)
With red and green lights (A), the 'Dirt
FINDER' system alerts the user to
areas of carpet that may need more
cleaning attention. It is able to sense
when larger amounts of dirt particles,
especially embedded dirt, are
removed.
To let you know that the 'DirtFINDER'
feature is ready, the red light will
come on when the cleaner is first
turned on. After a few seconds, the
red light will go off and the green
light will come on. Cleaning may
then begin.
The green light will remain on
throughout cleaning except when
the detector senses that a larger
amount of dirt is being picked up;
then the red light will come on.
When the red light is on, you should
take additional cleaning strokes in
the area until it changes to green.
• The red light may seldom come on
during cleaning. This means that
your cleaner is picking up primarily
fine surface dust and lint which the
system may not detect, or that the
carpet is generally clean. To
increase the feature's sensitivity to
dirt, set the switch (B) to the "Hi"
position.
• At other times, the red light may
stay on for a considerable amount of
time. This means that the carpet
contains a high level of dirt which is
being removed by the cleaner. To
decrease the feature's sensitivity to
dirt, set the switch to the "Reg."
(Regular) position.
