Would you clean these? 2nd and 3rd floor
Hard to believe someone could design this!

Obviously someone who never thought of window cleaning.

Theres a nice house that i clean that has a glass screen infront of a pair of upstairs patio doors, i cant clean them at all not even from the inside.
Like you say, stupid design

Open the doors,reach round 

[wfp master]

they must open in the way or they would hit the glass
screen.

[steven ainger]

this is the patio doors i was talking about, theres about a 3" gap between glass screen & patio door

I reckon you could reach almost to the bottom of the doors with another longer angle adaptor screwed onto a normal angle adaptor.

So the brush would be screwed into the long angle adaptor and angled downwards with brush facing towards the glass.

The long angle adapter could reach near to the bottom, but with a gap of only 3"s you need a very narrow brush with side facing bristles & jets on both sides

Yes a 3" gap is ridiculous.
The angle adaptor trick could work for the job the OP posted which is what I was responding to.
Although it's still not a perfect solution because you wouldn't be able to apply much pressure at all to scrub the glass as the angle adapter combination makes it very bendy.
Most buildings which incorporate those silly juliet balconies do have french doors installed which open inwards to be able to clean and maintain them from the inside.
The sliding patio doors in your pic Steve are plainly bloody stoopid.
