I made this last year it's about 7'6". I made this bigger one because the 6' one I made in 1990 and is still in mint condition was not high enough for the Victorian houses round here with the higher windows and ceilings.
They are much safer than stepladders the 3 point location works like a tripod in principle so they don't wobble or rock and you can use them no uneven and sloping ground.
I would say a must not just for window cleaners but anyone who uses a stepladder.
