Lightweight carry
At 4.9kg in use, this is light for an upright and that changes how often you will actually bring it out. It is easier to take up stairs, turn around furniture and move from room to room without the stop-start fatigue that puts people off bigger uprights.
The limitation is that the light build is the main comfort advantage, not a luxury feel. If you want something that glides with a very plush, highly articulated feel, this is more practical than polished.
