Ryan, I think it would be better to compare the Miele with a more high end, full sized cleaner of the era like a Sensotronic or Lux 2000 series. The Miele may be a heck of a lot bigger and bulkier than the Compact, but it's certainly ligher, quieter, more solid and higher performing.
The suction is incredible, but when using the cleaner on carpet (thanks to a well designed floortool) it just glides along, picking up everything in it's path. It leaves some lovely track marks in the carpet that you rarely see with a straight suction cleaner.
I managed to pick up a NIB turbo brush to match this cleaner, but so far I have not felt the need to use it. I'll get some pics and a better video up with the turbo brush at the weekend.
