rscole86: No idea how well it works, but I have heard that the applicator isn't very efficient and likely to leak.

Just gave this stuff a go, its crap tbh. The applicator started leaking half way around the house so lost pressure and had water flowing down my arm. 1/5 stars.

I use a telescoping window brush attached to a hose. After about 1 minute I am as wet as a shag so not a pleasant winter job.

Been there done that. The best part is when it runs down your arms in in your sleeves

I plan to modify it to make it better thusly: block off the hose attachment at the butt end. Glue in a hose attachment half way up the shaft. That way most of the inevitable stream of water will run down the hose before it gets to your arms.

Unfortunately I am better at planning than doing so hopefully one of you guys will implement my brilliant idea and let me know if it's worth doing.

I use the telescopic brush but not with a hose attached.

Swim averted. still a painy job which explains why my house looks like it does and the brush can only reach so far.

yeah the only factor that the extendable brush causes me issues, is the lead lights, because the squeegee is wider than the panes of glass, and getting it over the horizontals it never does a good job.  Also I'm a little paranoid about the panes flexing 

Wet & Forget do a spray on, light brush, rinse off product. https://www.wetandforget.co.nz/products/outdoor-cleaning/window-witch.html

No idea if it works, but they say, no squeegy. I've heard good things (mainly from them though) about their other products.
