No I agree with spiders nests on sash windows etc then you need to go slightly stiffer than a flocked extreme if I come across that I just stick the medium sill on it’s easily capable in dealing with those. In general a heavier brick of a brush imo is not needed like I say most of the time we are dealing with dusty windows not filth.
So clearly no need to spend silly money on a hot water system, like you say, most of the time we are dealing with dusty windows not filth.
I use hot water.
but fortunately, live in a soft water area , so I just fill my tank with hot in the morning through the DI
I agree that it doesnt speed me up, but its much nicer working with hot.
the pole hose is nice and floppy, I dont have to deal with it kinking or tangling anymore.
it is aso better on first cleans.
