FEATURES

DIRT SENSOR

7

Some ModelsThe dirt sensor light system is mounted onthe CT-20DXQS nozzle near the reset button.It consists of a series of two red lights andtwo green lights.

Initial Start UpWhen the CT-20DXQS is first started, the followingsequences occurs in a two second time frame:

1) Two red lights come on.

2) Two green lights come on.

3) Two green lights remain on until the CT-20DXQS nozzle is placed in use.

In OperationWhen the CT-20DXQS is being moved back and forth onthe floor, the lights will change from one configuration toanother as more or less dirt is being vacuumed. As longas the red lights are on, dirt is passing through the wandindicating that the surface still needs cleaning.

When the green lights stay on as the CT-20DXQS is movedback and forth over an area, the sensor is not seeingenough dirt to warrant further cleaning of that area.

Cleaning LensAlthough the dirt sensor feature in your CT-20DXQS isdesigned for years of trouble free use, the passage of dirtthrough the air passage system can coat the lens causingthe green light to come on and stay on - never switchingto red. When this happens the lens must be cleaned.

To Clean The LensesNote:DO NOT attach or remove handle or wands while cleaner is ON.

1) Remove the wands by pressing the easy releasepedal and lifting up on the wands.

2) As indicated by the illus-tration below, the twodirt sensor elements are located on the inside of theswivel, approximately 31/2" (90mm) down, (note thearrows). Each element should be cleaned periodically. Toreach the sensor elements, use a small brush such as abottle brush. Brush each sensor element several timesto remove dust and dirt.

Note:Looking down inside the swivel you will see a ring. Thesensor elements are located just slightly below this ring.

3) Reinstall the wands after cleaning the sensors.
