To be honest I don't think it crossed their mind - again, you have to weigh up the fact that so many brands didn't want cylinder sales to suffer. thus adding very little in the way of above floor cleaning designs on uprights, including a handle release hose attached and a hose that stretched to some distance. SEBO of course were different as they employed a patented hose and wand hoister release on the side of their uprights with nothing to do with the main handle of the vacuum.
Also during that time line of release, there were very few other brands who used clear hoses that could expand. Again, other brands just didn't "bother" experimenting with a stretch style hose that could compact within itself. Not to my mind anyway. [this post was last edited: 10/27/2013-13:41]
