On those cramped apartments where the handle of the wand is hitting the ceiling, or the stairs are spiral or turning right or left, you'll find that the wand is too long. Not to mention those stair cases where the risers need to be HWE. I've owned and used 5 different stair tools, and haven't found the perfect match yet. I'm quite frustrated, because my back gets punished. My shoulder and forearm got punished when I was cleaning the stairs with my normal wand in my early years, so keep that in mindI just use my wand
