Each one is missing the price tag?🥴

One of them is designed to be used on a fixed gooseneck simply because it's angled, the rest of them are fine.
 I started off using swivels which I made up myself in 2003 by stripping a Salmon tile grouting  brush of it's few very stiff bristles and cutting it down to the size of the swivels out today and laid it over the top of an original Tucker brush which worked very well as no one sold swivels back in them days. I did it to overcome an illness I had enabling me to work easier.

Were you called Gaz in a former life WW ?

I can't remember who I use to share some of my ideas with back then. I know Gaz use to use similar Salmon brushes. I use to go by the name of easy clean when I started on here

Sorry. His business name was Advance window cleaning. and his name was Gary Hollins.

He was H h20 back in 2007. He is now a guest and you can't do a search on his posts.

I still have a functioning, albeit, decommissioned MKII Gaz swivel!!

The MKI Gaz swivel is still unbeaten- in certain aspects, it's just a shame the Salmon brush was such a let down!

Ladies and gentlemen, CLEVIS has left the building.

So what’s the problem?
They work (well Gardiners does) and cheaply. They do wear eventually but no problem. The resistance is also adjustable.
No problem!
You could copy the wagtail, that seems a reasonable swivel but has a lot of surface area to rub.
You could stick a bearing in there, no point.
It’s just a brush on a stick.

It does what it’s supposed to do, what more do you want?
The concept of telescopic poles rubbing themselves to destruction at £1000 a time seems worse to me.
So, to answer your original question, no I don’t see a problem.
The problem can only be that they don’t look like yours and you believe your design is far superior I guess.

Said nothing about the design but the question was about the mechanical problems they all have.
And already pointed it out.

Get on with cleaning windows instead of finding faults in other suppliers products that you don’t even use. What’s the point in this? Have you not got a life ?? Nothing better to do with your time? Not got Netflix??

You ask us to  find a problem with what’s currently available and IMO works well enough.
I don’t see a problem. Maybe it  only exists  in your head?
You’ve posted a picture with no explanation of why it solves the imaginary problem.
Why you persist In trying to reinvent the wheel and post in riddles is beyond me.
I’m out
