or inevitably gets tired

The triggers are so light, I fail to see how anyone could get tired. It basically requires no more grip than just holding it.

Or the amazingly useless "smart power" feature that just varies the power almost completely randomly as I vacuum an otherwise perfectly smooth hard floor.

Oh no Dyson did that too? I assumed it was just Shark.

It's clearly a hack so they can lie about amazing pickup and battery life (....but not at the same time)
