The invention is an agitator configuration for a floor care appliance such
as an upright vacuum cleaner. The floor care appliance is provided with
at least two agitator chambers each having at least one rotary agitator
member disposed therein. In the preferred embodiment of the present
invention, a vacuum cleaner suction nozzle is provided with symmetric
left and right agitator disposed adjacent one another. A front agitator
assembly comprised of a left and right agitator half-section is disposed
in the left and right agitator chambers, respectively. A rear agitator is
located rearward of the front agitator assembly and is also comprised of
a left and right agitator half-section disposed in the left and right
agitator chambers, respectively. A plurality of brush members extend from
each agitator half-section arranged in a helical pattern around the
circumference of each of the agitator-half-sections. The left and right
agitator half-sections of the front agitator assembly have opposite
helical patterns so that a "chevron" pattern is formed from the front
agitator assembly. The "chevron" brush pattern sweeps dirt particles from
the center of the suction nozzle along the front of the cleaner toward
the suction nozzle's outer edges. Similarly, the left and right agitator
half-sections of the rear agitator assembly have opposite helical
patterns so that a "chevron" pattern is formed from the rear agitator
assembly. The "chevron" brush pattern sweeps dirt particles from the
center of the suction nozzle along the rear edge of the suction nozzle
toward the suction nozzle's outer edges.
