go furthest point first, then work back. the less pull reel out is usually easier, so will prob do all the back, then side, then front and other side. tho each house/shape/ obstacles are different.
you need to leave a couple of mins, occasionally more, before do window below one that you've just cleaned upstairs, but again that can be unique to each house, or type window, sometimes water runs down the wall and needs longer maybe 4 or 5 minutes, sometimes 30 seconds can be enough.
