First off, Peter's clip is no stunt, I wish there was a way that he could grab a handful of you cynics and prove to you all that a window can indeed be cleaned properly just as he does in the video.
Maybe we can find some disbelieving Scottish window cleaner who is prepared to travel to his neck of the woods for a demonstration on a days work.
I'll lay money on the fact that Peter is prepared to stand up and be counted too.
Ionics already do a domestic reach and wash system...doesn't matter though, it still takes skill to do and you still have to buy resin and maintain the system.
People have a window cleaner because they just don't want to do it themselves.
I suppose some carpet cleaners may well go for it, but have you seen some of the equipment they have in their vans now
Can't imagine them wanting to get into window cleaning too, besides, they would clash on timings, People in domestic homes only have carpets cleaned when they have too, window cleaning is done far more regularly.
Might be ok for one off cleans when they are in situ I suppose.
Would really need one of the guys from the carpet cleaning section to answer that one properly.
Can't imagine a maid service wanting to know about it either, it is still a physical job for a woman to do, and few men are in this line of work.
An interesting thread though
