Really! I thought it was just me
Anyhow after seeing wagers old vid using the prototype jetstream it may just work fine on glass Juliet balconies. That's if I can get it in the narrow gap and can get the right angle working directly underneath it.
In principle being a swivel mop and having a top rinse bar can give them a good scrub and rinse at the same time which sounds good to me. Then also being a mop if need be can also use chems/soap if need be then give them a good rinse off.
Using a jetstream should be a darn site easier as they are filthy than trying to use normal trad gear, little waffle cloths etc on them and/or up a ladder trying to clean them from the top.
By the way those glass Juliet balconies has never been cleaned. Even their last window cleaner refused to do them.. I wonder why
