the one thing I dont understand be how come miele , know for its light and quiet yet powerful vacuum , come up with this unfunctional thing . very heavy , not easy to glide from floor to carpet . suction power be just ok . and it be 400 something dollar . I have own many vacuum -lrb- cheap and expensive -rrb- and this one have be very disappointing . if you be look for something powerful yet not as heavy take a look at Miele 's s5 or s4 line but definitely dont buy this without try it .
