I think I need a new one - but it got me thinking - is there an optimum bristle length - and why?

I think this could make a good doctoral thesis subject.
What are wanting to sweep up? What surface are you trying to sweep?
Inside on smooth vynl tiles and fine dry dust a 2 to 3" long soft bristol works well. Same length stiff bristles don't but outside with saw dust on ridged concrete (as left by the tamper to provide a little bit of grip) the stiff bristle brush does super job.

it is promounced yerd brush in Glasgow ....
Yes, and it's linked to the Rayleigh damping coefficient of the material, the speed and force of brushing, and the surface material.

And how lazy, or otherwise the apprentice is, since it is usually his job to sweep up.

I've found with brushes the main difference is the bristle material and their spacing. I recently purchased a a brush with very stiff plastic bristles and its absolute crap for sweeping. There isn't enough flex in the bristles and the head tends to skip over the surface.
In addition soft brush for light dry dust and a stiff brush for wet compacted dirt (unless using a lot of water to help shift the muck)

A friend always used to stick a Bloody Big Magnet in his one ... picked up all sorts of metallic debris that was destined for a tyre somewhere ...
Thats a pull behind brush. No good for pushing
