ELI5: Why can you feel the air blowing out of a hoover from about a meter away, but the suction on the end of the pipe can only be felt a couple of inches away?

Its the same quantity of air moving, so why the difference?

The suction isn't directional in the same way. The air just next to the pipe is sucked in, and air from all directions moves in to replace it. When air is blown out, it's being pushed in a particular direction and carries on in that direction rather than spreading in all directions. In that one direction, you can feel the effect over a longer distance.
