ELI5: does vacuuming slower really pick up more dirt, why or why not?

I've always heard it does, but I have my suspicions.

It gives the vacuum more time to pick up debris. There is a point of diminishing returns, where more time spent on one spot does not significantly increase debris picked up, but you will get more stuff off your floor if you spend 5 seconds/meter versus 1 second/meter.
