They're full of shit if they think a shiner can clean those lower floor windows from the opposite bank.
got to agree with you , we would do the top half from the other side using an ex 47 , not saying it would be easy but the hubby is use to doing high stuff from the ground all day every day in the usa ,so i would expect a good job from him on this
however , the lower floor windows would be a nightmare poling it from the other side , even with the brush straight on or stepping to the side and doing it side ways but straight using a ex35 it would take some controlling
i guess this is where the last w.c. failed and just made do , maybe just rinceing them and not even touching the glass with the brush ?
my guess is it the down stairs people kicking up a fuss about how poor the cleaner is
