Cordless sounds great. I've had my amazing Tefal steam station for many, many years (we moved here in 2009 and I've had it for a while by then)- and I even dropped it a few time! Just would not be without it- but we have high limescale here in the Jura, and I am meticulous with cleaning it properly with the device given and a bit of vinegar, about every 2 months. Would love to hear about the results with the cordless for when it goes.
Just like with Hoovers, reports show that poor maintenance and cleaning is the cause of most irons failing early (sadly for the environment).
