I'll give a simple answer.
An ideal vacuum is simply nothing. It does not pull, it exerts no force on objects. Within a vacuum, far from a gravitational field, objects in motion simply travel in a straight line, the vacuum exerts no force, no resistance, upon the object.
I'm speculating that the idea of "pulling" comes from "explosive decompression" seen in movies, what happens is that atmosphere within a spaceship is pressurized, it is pressurized by the walls of the spaceship which are strong enough to hold the air pressure. Pressure is related to the velocity of molecules within the gas, in air at room temperature and standard atmospheric pressure, the molecules are travelling very fast, about 500m/s, this is 1800km/h or 1100mph (google "speed of air molecules"). All these molecules are zipping around at tremendous velocities and bouncing off each other and solid objects, because the particles are so tiny and there are so many of them and they are bouncing off us from all sides the force evens out, and we just know it as "pressure", which normally we don't even notice.
So in the spaceship, there are all these molecules zipping around at 1800km/h, but being contained by the walls. Then something makes a hole in the wall, suddenly the particles are free to shoot out the hole at 1800km/h. And that is exactly what happens, all the particles which would have bounced off the wall, instead shoot out the hole and travel off into space at 1800km/h.
Please note that "explosive decompression" as seen in movies doesn't happen in reality. You can't get sucked out of a hole. In fact, you could plug a hole with your finger. Rather it's just like I described it above, the air molecules which would have been contained by the wall, instead shoot out into the vacuum, so the air gradually escapes, as air escapes it will create a low pressure zone near the hole, which then creates a wind towards the hole. But it would not be explosively violent.
