Perfection is not of this world but Dyson approaches it with this upright vacuum cleaner. First positive point, the installation is of great simplicity; the battery is charged (fast loading, about 2 hours, but I was not very accurate in my counting) and go. The small motor is directly at hand (what overall lightness in the 2 kg only!), We see the dirt gently fill the receptacle and it is used only as needed because the engine just press the trigger function of what one is doing. Finished vacuuming that runs constantly even when aspires anything that moves items, etc. Equipped with several brushes and nozzle, the main brush contains a mild nap roller which adds to suction in turning on itself as if to scratch the ground and find the dirt. A wall bracket allows to hang the refill engine. The question of the power of aspiration must be evoked: from my point of view, this power is very ample and compared to my old Miele, I see little difference. The Dyson is wireless, which is just beautiful, but also means a theoretical limitation in the duration of use. However, if one has not a palace but a reasonable clean surface (eg 70m2), autonomy is more than enough since the engine is not running continuously as specified above. A fault? If we had to find one: the sound a bit shrill engine which by its smallness and its proximity to the upper body, sounds strong and sharp! For the rest, Dyson thank you!
