How to move a wardrobe without scratching the floor?

You get up on top, or do levitation with him. - Kidding of course.

There may be mutli solutions, I used just one. We know that to pick up a wardrobe is a lot of power, but to pick just one part of a corner, requires no power anymore. So I picked a corner, and as I put one foot slice of potato. (Take a medium potato and cut slices about 1cm thick). Then I picked up another corner, and another, and so on. Then, it was a breeze, because the slice of potato wardrobe simple and beautiful slipped.
