Do not forget about the original consumables - without them, even the most expensive vacuum cleaner will lose its meaning. Bags need to be changed according to the degree of filling, the HEPA filter is about once a year (it has a replacement indicator on it). Pros: A wonderful vacuum cleaner - very convenient in everyday life, German build quality (excellent plastic, durable metal). In general, it is difficult to add something - the quality of Miele appliances is always on top. With its cons. The high price is the first minus. The second is that in the basic configuration there is a not very wide brush for cleaning parquet - it is better to buy the widest one in order to speed up the cleaning process (but it is also not cheap).
