Cleaning windows on the outside for high floor flat

[Hellokitty]

Hey peeps! Can I ask for those of you who are staying high floor.. How y'all clean windows on the outside?

Magnetic window cleaner will be good for you. Clean both the inside and outside of windows at the same time.

I always clean it with vacuum cleaners and then use a long stick to clean with wet cloth to clean the stains and marks from windows. For the glass cleaning, i use the newspaper and tissue papers.

Can you tell me, how effective are these?
Stick and wet cloth are such a pain.
