Most swivels move side to side.
However when using you go to move side to side then try changing to a vertical there is a part that has restraints due to no curvature at that point.
Having curvature at this point allow a smooth transaction between horizontal thought to vertical as you using a squeegee or water fed brush.
Hope this explains it a bit better.
But that won't work for a wfp brush swivel.
Herman, I have a lot of respect for you, but you are pushing a product that no longer has any real relevance to British window cleaners. You are trying to promote an outdoor nudist resort in the Antarctic. The next best thing for the home entertainment industry isn't a black and white telly. The British market for new squeegees is very small. Yes, we each (son and myself) have a conventional squeegee but we hardly ever use it. My squeegee will still be around after I die. I doubt I've replaced the rubber in the last 5 years. (When we were trad we swopped the rubber around every couple of days to get a sharp edge and replaced the rubber once a week.)
You might try forums in the States because they have a higher demand for traditional tools than those of us the frequent UK forums.
As has been already commented on, you are trying to push a product that has long since died. The horse and carriage stopped becoming a popular means of transport for the masses in the UK some 100 years ago. There are still a few around but trying to market one with air suspension, double glasing, a diesel air heater and a new range of alloy rims with low profile wide wall tyres isn't going to get much interest, even with the Royal Family.
Unfortunately for you (and fortunately for us in the nicest possible way), you 'sold' your Quicklok concept to Gardiners for a 'bowl of soup'. But then you also didn't have the financial resources or the backing to patent it and produce the product yourself.
You need to be thinking about new products that will be the next must have. Unfortunately you are in competition with Gardiners and Exceed who are in a much better financial position to develop and market a new product. But again, each of these businesses have produced accessories that were discontinued because of a lack of interest and demand. You know as well as I do how much the dies cost to mass produce plastic components. These costs have to be absorbed in the cost of the product.
There is a cleaner on Youtube who has done a review of Gardiner's latest rinse bar. He was complaining about the cost of it in the review. He wouldn't have said that if he knew how much the die costs to produce that rinse bar. The trouble is that its also produced for a very limited market in small quantities. He wasn't looking at the bigger picture as the cost of dies is reflected in the price of the component.
The only suggestion I have is to revolutionise the window cleaning market like wfp did with the help of H&S. If you could develop an ultrasonic box that doesn't look like a gun that we could point at each window, pull a trigger and the dirt instanty dissolves, then you might be onto something. It must be rechargeable though.
