To Clean Dirt Sensor Optics
Optic Cells (Inside)
Cellues
➢The dirt sensor optics consist of two optic cells located inside the suction inlet. Occasionally, it may become necessary to clean the two optic cells to assure maximum performance.
➢Clean optic cells:
•When dirt or dust adheres to the optic cells.
•Whenever the dust bin is cleaned.
➢To clean the dirt sensor optics, remove extension hose at the suction inlet.
➢With the hose removed you can insert a cloth into the suction inlet opening.
➢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.
