From Germany, the very BEST of the BEST powerheads ! A life time geared belt and easy remove roller brush makes cleaning carpet or bare floor so very easy !Move from bare floor to shag and adjust a bit and life is good !The beauty in this powerhead is the operation and the cleaning after you are done. A squeeze, a twist and that is all it takes to remove the brush for cleaning. Such a brilliant design ! One dance across the floor and you will love it !
