I've used the Mity Vac twice to bleed my clutch. I had no problems with it either time. The clutch pedal should be completely up. Bubbles coming through the threads were annoying but I don't think that it allowed air into the system. Just make sure that the reservior never gets low during the bleed.

If you still can't bleed completely, you may have a leaky seal. Just a guess.

I agree with IceShark. The pressure bleeder is much better. I helped a friend with his Mercedes and a pressure bleeder. Quicker, more thorough, and less messy than a vacuum bleeder.
