What is a Dirt Sensor?

The clean carpet sensor on an upright vacuum cleaner detects dirt being picked up while the vacuum is in use. When the vacuum is picking up dirt, a red light on the vacuum will flash to indicate that the suction is effectively picking up dirt and cleaning the area. Occasionally, the light may alternate quickly from red to green if the area is only lightly soiled or if the dirt is spread out. To ensure all the dirt is picked up, keep vacuuming until the dirt sensor stays green with every motion.

Uses of electronic dirt sensor

  • Ensures that there are not any unseen dirt particles left behind after the first round of vacuuming
  • Makes cleaning easy by calculating soil levels on floor surfaces
