if you had a pressure assist toilet you could experience the danger of a pressurized bomb in your toilet with the suction force of a black hole and you wouldn't have to flush in "stages" personally i like to place my balls on top of the toilet tank as i flush for the rush i get knowing that at any moment it can explode into billions of pieces of shrapnel.    no, the whole system is self contained. it automatically sucks in air through the tube and the one way gasket on the top right of the unit. it hooks up using all standard parts of a toilet, no need for extra hose lines or electricity.
