The range of silent rowenta force since its release been among the best vacuum cleaners in the world, thanks to: Exceptional depression (kPa) Unparalleled suction noise (we no longer hear the turbine, only the sound of suction at the suction head) An exemplary filtration salting virtually no particles. (Hepa ...) An energy ratio (kPa vs. consumption) on top.
In short I am in my second silent force and you can go there with eyes closed, though for very dusty or dirty areas (animal ..) models prefer the bags, though less demanding in interviews, do you think the Machine washable zipable bag, to find the ease of a no daily bag.
