Sweepers have evolved remarkably slowly over the past 100 years, to the point where even current models are grossly inefficient. The Eiffel Broom is a great improvement on the straight-edged dust brush that requires you to keep cleaning the same area of hardwood or tile.
What's different about the Psychic Factory's adaptation is that the line of bristles has been altered so that it forms an arc shape. It might offer only a single and thin row of tufts, yet this rounded form makes it a great deal more effective. As you gather dust, scraps and debris across your flooring, position the Eiffel Broom such that everything collects into the concave area. This will ensure that dirt doesn't escape to the sides.
