I'm personally glad that the industry in wfp has developed to where it is today. Could you imagine if the industry stayed stagnant with the first lot of poles etc that came out and used the argument that, if it isn't broken don't fix it, attitude.
Granted in my opinion there are some gimmicks and variations that I don't see adding much difference. Such as vision for instance, but that said, I have never tried it so I can't really give an opinion about it.
Personally for me, i like an heavy brush and plenty of water cascading down the window to help with the clean and a faster rinse. I also know my brush and know that on my technique I can rinse on the glass with no problems and any dodgy seal or top frame, I can adjust the technique accordingly. Which is knowledge and confidence in my cleaning ability and not as some view it, as the reliance on hot water or rinsing the window to death.
Wouldn't life be boring if everything was the same and no additional choices or personal preferences were allowed.
Any car can get you from A to B.
Any style of clothing will cover your body and be suitable for its intent n purpose.
Same can be said for hot beverages, cold beverages, alcohol, food, shelter etc etc the list goes on. Can you imagine only having the one of each ofthe things mentioned, because at the end of the day, it does the job and that's all that matters. Yet ones want to insist that the same logic here doesn't apply in our line of work. In my opinion this line of thinking is limiting.
