It wouldn't matter, the area between the agitator and the lower arm and pump intake is a harbor for all sorts of stuff, which gets flung around as it contacts the spinning spray arms. The smaller stuff gets sucked in and sent up to the spray arms, which is why you occasionally get clogs in the arms. The pump intake finally grinds the stuff up small enough to get through the screen.
