I had a very similar staircase in my old house. Making the turn may be tricky given the depth of the machine with the head down plus the Escalera plus your body. There was just enough room on my staircase but I had to breath in and muscle it around.

Highly recommend you include the step edge detection system option. It makes it much easier and safer to position the unit AND keep it at the right angle. I found the hardest part of the learning curve is keeping the machine at the right angle. The tendency is to lean too far back to be safer which can cause the unit to slip down multiple steps. And leaning too far forward can end in disaster. The edge detectors are easy to see and indicate the right position and angle.
