After we "squeak" from the standard brush while sucking our hard floors (floor tiles, laminate flooring) were quite annoyed, I simply ordered the Siemens VZ123HD brush for hard floors - it is now not only a treat for the ears, but also sucking ansich gets easier. Another big advantage is that the dust really ends up in the vacuum cleaner and not as in the standard brush between the folded strip of bristles and the plastic housing or the inner workings of the standard brush.
