corded version
I actually talked with someone at Wessel Werk about this, apparently a corded version is not commonly made, but it is possible. Apparently the electrical connector on the nozzle is called a c7 or c8, it's a common electric connector in Europe. You would need to make your own cord with this connector on one end and the two prong mini connector that is typical of electric hoses on the other. Apparently there is actually a cord inside of the direct connect telescopic wand, if you could somehow open the wand and remove this cord, that would also work.
