because i can see them coming down in price, b and q selling them then window cleaning becomes extinct everyone buys them the domestic customer start cleaning their own windows
I don't see this happening any time soon. The fact is, window cleaning requires special equipment. Ladders are not too expensive, but do people who have their own ladders clean their own windows? No, Never.
Are people going to research/ buy/ use pure water equipment themselves? Even if they do buy it thinking "Ah, this has cost me £200 but it'll save me that in a year by not having a window cleaner" what will happen? It'll sit in the garage, the wife will moan about the windows, there'll be no time to clean them etc. [Saturdays are for golf surely! I've spent all week at work now its time to relax, not clean stupid windows!] Eventually the wife will ask the next passing window cleaner they see.
Only the most disciplined of husbands cleans their own windows, and these are the sort who would do it with ladders anyway.
I dont think we need to worry about it too much!
Silly
