I've just WFP last week. I have an Unger HiFlo nLite brush and the bristles keep keeping caught in the frames. Is this because it's new? Problem being they get well and trump wedged in there and no wcubbing will get em out.

Secondly: what is the best day-to-day brush in your opinions?

I have a couple of houses where the odd window frame steals some bristles
I think it's where ther is a little gap between frame and push in seal
If you're loosing loads there could be a problem with the brush but having not used that particular brush I don't know exactly what they're like
I prefer gardiners brushes, double trim mono extreme for most windows and double trim flocked extreme for leaded and wooden Georgian types

Gardiners extreme medium mixed. 
As for bristles being taken by frames, yeah, this happens from time to time. But like Scott says, not used an Unger brush, but if it's leaving lots of bristles behind, maybe there is a manufacturers fault with the brush? Best quiz your supplier.
