I think the pressure of the suction is proportional to the amount of time you dig into the gravel: longer time, more gravel sucked by the siphon.
i saw the staff at Petco just dig in for about 3 secs, get the siphon off the gravel, gravel drops back to the bottom of the tank, and then he moves to the next spot.
