Maintenance of Dirt Alert Feature (On some models)
The dirt alert sensor uses infra-red technology to indicate whether or not floors are clean. When debris breaks the light
beam, the red light comes on indicating additional cleaning is needed in this area. If there is no break in the light beam, the
floor is clean and no light will come on.
When using your new vacuum you may be cleaning deep down hidden dirt missed by your old vacuum causing the light to
stay red longer. With frequent cleaning, after the first few times you use your new Eureka vacuum, the red light should go
on less.
The red light indicates dirt, dust, etc. is still being removed
from the area being cleaned.
NOTE: The dirt alert feature is not intended to be used for above the floor cleaning with attachments.
To check if dirt sensor is working properly.
1. While the red light is on, tip the vacuum backwards on rear
wheels, lifting the brush roll off the carpet a couple of inches.
2. After a few seconds the red light should turn off.
HINT: New carpeting has loose carpet fibers which will
trip the red light sensor beam.
