Thank you and sorry for the delayed reply!
I really love using this vacuum. For my new home, it’s perfect. I bought this having never used a Sebo X-series vacuum before, so a few things surprised me
1) The proportions of the vacuum are unlike those of most American machines. The Sebo is the tallest vacuum I’ve ever had and has a narrow head, making it quite maneuverable.
2) This vac has some suck! Don’t let videos of the European X7 mislead you; this 1300W+ American model holds its own.
3) The automatic height adjuster actually is convenient. I’ve come to appreciate the system which Sebo has put in this vacuum. It seems to have some kind of (perhaps rudimentary, but still effective) PID controller whose input is the RPM of the intermediate pulley, and in the end, it works well. It makes the same decisions I would make, lowering the head for the more crushed portions of the carpet and raising the head for the less trafficked areas. I’d say that Sebo did a good job striking the balance between minimizing carpet wear and cleaning effectiveness.
I’ve had several Míeles before, but this is my first Sebo. Sorry; I can’t really compare this vacuum’s control system to that of the X4, X1.1, or X1, but the X7 doesn’t seem “fickle” like the older ones are sometimes characterized.
Incidentally, I suspect that the vacuum looks for elevated RPM to determine when the bag is full. I’d be surprised if it actually measures pressure anywhere.
Boost is fun, but I think that the vacuum does well without it, too. Without boost, the vacuum was able to make the lines in the pic below. Honestly, I never really use boost.
Overall, I’m very happy with it!
