Unfortunately, we could not convince the broom in use. As to the product illustration can easily be seen, the brush head has a crescent shape. Along with the "innovative bristle shape" should be possible as an even faster and more thorough cleaning. Unfortunately we have but done exactly the opposite experience. Although in fact dirt particles of all kinds are (coarse, fine, light, heavy, dry, wet, etc.) recorded good when sweeping in the forward movement, even if not significantly better than that of other high-quality brushes, which we hitherto in use had. But unfortunately failed the broom in this respect quite in the backward movement, so if you do not just return to the front (in quasi "arrow"). This is probably due to the position of the bristles, which are not designed to slip backward movement. If you want to exploit the backward movement habitually, is the return to a test of patience.
One wonders what this is - a broom that returns only one direction?
Thus, it is of course more difficult to turn in tight spaces, or rauszuholen dirt out of corners. Since it is almost not at. The crescent shape of the brush head is indeed an exception and quite possible there is a reason has proved perhaps because the straight, or rectangular shape is valued for thousands of years? Innovations are a great thing, but they should also bring an improvement.
So but the bottom line for this broom in a word, unfortunately, "impractical"
