DIRT SENSOR
The electronic dirt sensor is a feature which
will detect particles as they pass through the
vacuum cleaner.
The dirt sensor indicators and sensor
sensitivity switch are located on the front of

A red light Dirt
indicates dirt is Sensor
being picked up by
the cleaner. A
green light
indicates most

been 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.
The green light indicates that most of the
cleaning is complete.
The sensor switch allows you to select the
sensitivity of the dirt sensor. The switch can
be set to HI (+) or LO (-) sensitivity.
Set the sensor switch to the HI (+) position when:
• Cleaning bare floors.
• Cleaning carpet with low pile height.
Set the sensor switch to the LO (-) position when:
• Cleaning heavily soiled areas.
• Cleaning carpet with deep pile.
• Cleaning new carpets.
Even with the
sensor switch in
the LO (-)
position, the dirt
sensor will detect
carpet fuzz,
especially on new
carpet, which
may cause the
red light to remain
on longer than
expected.
