If you blow on something with your mouth, you can blow it pretty hard. Like if you had a paperball on a table, you could blow it pretty far. But if you tried to suck in air to bring it towards you, it would be incredibly difficult, and you'd have to be extremely close to it.
The same seems to apply to mechanical devices. We can make devices that blow extremely hard. Leaf blowers can blow leaves a long way, but there aren't any device that can suck leaves in from that far away. To suck anything up, you have to be pretty close to the object. To blow it, you don't have to be close at all.
Why is sucking and blowing so different?
