Embedded DirtFINDER™
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.
