I've worked on my whirlpool... get a good vortex going and keep stirring until you feel like your arm is falling off. Let it sit for 30 minutes. Accept the fact that you will get some trub in the fermenter so put the end of the cane at the edge of the kettle and let it go, dont keep moving it around from edge to edge trying to avoid it. You will suck up what trub is left in that one spot, but it will clear out quickly. Here is what I have in my primary - this is after about 10 days.
