Why mechanical compact spinning is going to supersede pneumatic (vacuum / suction) compact spinning.

Compact spinning was founded way back in 1999. Soon after in 2003, mechanical compact spinning was invented.

Until now, pneumatic compact spinning was widely adopted, only for spinners now to realize, that mechanical compact spinning is going to be the future. Why is that?
