As you vacuum, the amber and red
indicator lights will come on and stay on as
long as the sensor detects a high
concentration of particles passing through
the vacuum cleaner.
TO CLEAN DIRT SENSOR OPTICS
The dirt sensor optics consist of two optic
cells located inside the dust bag port.
Occasionally, it may become necessary to
clean the two optic ceils to assure
It is recommended the optic cells be
- When the red light stays on
- When dirt or dust adheres to the
- Whenever the dust bag is removed.
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 cetls and make it
necessary to clean them much sooner than
normal. The dirt sensor area can be
reached by removing the dust bag.
