Does anyone use, or have knowledge, of powered bee brushes? I stumbled across a video a few months ago wherein a beekeeper with a beehouse arrangment used one to clear bees from honey frames as he pulled them. From what I could see, the system utilized two cylindrical brushes that counter rotated. The honey frame was passed between the rotating brushes and was very quickly cleared of bees. Not sure whether the bees went into a container or a duct to the outdoors.
I have search about bee supply houses but cannot find anything of the sort. The management strategy that I am leaning toward requires pulling individual frames of honey rather than supers so such a machine might be very useful.
I am particularly interested in hearing from anyone that has used one as I am curious as to how well the bees cope with such a machine.
