Before that, they used the previous Miele S5311 model. Years 8. The vacuum cleaner was perfect. But in connection with the repair in the apartment, he gradually moved into the category of "construction waste." Got a new one. Miele was chosen again because of the power. Not disappointed. In fact, the vacuum cleaner is almost the same. Minor design changes and improved filters. Power, on sensations, even more. I hope it is as reliable and easy to use as the previous model.
