No, because depending on the type of carpet/surface to clean, you will select the appropriate side to use, either the wire bristles or for knotted, more sensitive surfaces the red velvet-like side. Test first on the surface, which side works best, and pull in the material’s alignment. Make sure the plastic protected wire bristles are used on surfaces where it doesn’t get stuck in the fabric/loops. Consider the alignment of the fibers for more efficient use – you will feel when LeBRUSH glides easily through the surfaces, this is when use is optimized.
