DIRT SENSOR
SOME MODELS
The electronic dirt sensor is a feature
which will detect particles as they pass
through the vacuum cleaner.
The dirt sensor indicator is located on the
front of the switch cover.
The red light indicates dirt is being picked
up by the cleaner.
OPERATION
As you vacuum, the red indicator light will
come on and stay on as long as the
sensor detects a high concentration of
particles passing through the cleaner.
No light indicates that most of the
cleaning is complete.

Hazard
Disconnect electrical supply before
servicing or cleaning the unit. Failure
to do so could result in electrical
shock or personal injury from cleaner
suddenly starting.
TO CLEAN DIRT SENSOR OPTICS
The dirt sensor optics consist of two optic
cells located inside the bag holder.
Occasionally, it may become necessary to
clean the two optic cells to assure
maximum performance. It is
recommended the optic cells be cleaned:
•When the red light stays on
continuously.
•When dirt or dust adheres to the
optic cells.
•Whenever the dust bag is changed.
To clean the sensor, wipe the optic cells
with a soft, dry cloth. Never use cleaners
or liquids as they can help speed the
recoating of the optic cells and make it
necessary to clean them much sooner
than normal. The dirt sensor area can be
reached by removing the dust cover and
the dust bag.
