It is
a wonderfully powered and quiet stick vacuum. I found it is never necessary to use the high motor speed. Low is more than sufficient.
Interestingly, the power cord is quite long, unlike Miele canisters. The combination floor - rug brush does a good job. However, threads and dust firmly affix themselves to the stiff bristles and are very hard to remove. (this is the only attachment I have as the cleaner is used exclusively for quick hard floor cleaning)The K" series dust bags work well and hold quite a bit.....no need for the HEPA filter as the "air-clean" pad included with the bags is more than good enough.
The most significant annoyance with this cleaner is the lack of some sort of "kickstand". Even when carefully rested against a wall/door jamb, it tends to tip over with a crash. The rubber hand hold is supposed to grip whatever it rests against and alleviate this, but it really is unreliable. Laying it down on the floor is the safest way to take a break. Miele should develop some sort of on-board easily deployed support.
Hope this helps!
