disappointing as an alternative to RO 462,711

We use a few years RO 462,711 with much satisfaction, and we wanted to acquire a second to cover the surface of our Locations. This model is presented as the successor of 462,711, more economical and equally effective. This model comes with a crevice tool with wheels cumbersome, difficult to handle (and super loud on tiles) and much less efficient than the triangular nozzle précédent.En adapting to the triangular beak of the previous model, the new vacuum cleaner is less effective suction. In short, less powerful and less effective than RO 462,711 contrary to what is advertised.
