This would be a great agitator for the new 2010 Whirlpool washers with their 360 degree extra slow agitation arc. The Kitchen Aid Sure-Scrub agitator that have the "SUPER-SIZE" flex-vanes.
But, combining and "mix-matching" the super-size flex-vanes with Kenmore's 20 degree UNDERCUT spiral vane agi-auger would complete the PERFECT agitator.
The 360 degree agitating sweep and super-size flex vane will create "POWER-WAVES" rollover water surges. The undercut spiral will allow you to wash larger loads than the regular Sure-SCRUB agitator.
