1. A vacuum cleaner comprising:
- a suction head configured to draw air from a surface as the suction head is moved over a working area of the surface,a sensing system for sensing a presence of dirt in the air drawn from the surface by the suction head, anda sensor-responsive light system on the suction head and positioned to project light away from the suction head and onto a first region of the working area forward of the suction head based on the presence of dirt in the air drawn by the suction head.

Abstract
A vacuum cleaner having a floor nozzle movable by a user of the vacuum cleaner over a floor to suction dirt from the floor. A sensing system is provided for sensing a condition relating to the vacuum cleaner and for generating a signal in response to the condition. A sensor-responsive light system on the floor nozzle is responsive to the signal for projecting light onto the floor for observance by the user.

7. A vacuum cleaner comprising:
-
a suction head movable by a user of the vacuum cleaner over a working area of a surface to suction air from the surface, an illumination system for projecting light onto a first region of the working area to illuminate the working area, a dirt sensing system for sensing a presence of dirt in the air drawn from the surface by the suction head, and a sensor-responsive light system for projecting light onto a second region of the working area based on the presence of dirt sensed by the dirt sensing system, wherein the first and second regions at least partially overlap one another on the working area. - View Dependent Claims (8, 9, 14, 15, 16, 19, 20)
