Abstract
A vacuum cleaner generally has a working head which is positioned on the floor surface when the machine is in use. The working head of a vacuum cleaner essentially includes a rotating brush, a suction blower and a motor for operating both the brush and the blower. In addition, this working head also generally requires a spacing device, such as a wheel for guiding the brush head or suction brush head and controlling its proper spacing in relation to the floor.
