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.

NOTE: The dirt alert feature is not intended to be used for above the floor cleaning with attachments.

The red light indicates dirt, dust, etc. is still being removed from the area being cleaned.
