Cool... wonder how much it is. I can't imagine it being quieter than a Miele, but I do like the looks and feature set.
As a rule, I don't like combo tools, but I think that one looks OK... as long as the "wings" that become the upholstery tool don't break with constant opening and closing. There seems to be some depth the the bristles on the dusting brush so the plastic won't scrap the surface it's vacuuming unless the suction is just too crazy. But, the suction can be turned down, so it shouldn't be an issue. The crevice tool may be too short for many people... but I don't use a crevice tool at all really... and as long as it has a quick release power nozzle for baseboards and around the litter box, I'd be quite happy with it.
