I picked this up from CPC (part of Farnell) recently, its basically a magnet on a handle. With the handle released it picks the swarf up, with it pulled up it drops it off.
My wife is very forgiving about oily finger prints and the like but gets a bit twitchy about me bringing swarf in. I've been using one of those cheap little telescopic magnets but it took ages to do he whole floor. This gizmo works well and picks up most magnetic swarf, a quick wizz over with an old vacuum gets the rest. Cost was £17, with some change, delivered, I consider it to be a good buy.
