Wow! That's the thing I've been looking for. I can't keep up with Kitchen-Aid's price point rise and also its countertop footprint. Kenwood's compact Prospero -- a real stunner -- might well be the ticket but it isn't on the market here.
As for the turbo nozzles, I have used several versions over the years. They're more or less if all you need to is a light clean. Due to the nature of their operation they need x-amount supply of incoming air keep the turbine turning the brushroll at a reasonable rate. That's why they have vents. Block the vents and rely on air coming through the brush chamber and they begin to stall. However, if your rugs are light and low pile and not subject to heavy traffic you might get by.
Just to mention, Miele cans usually only a score of good for carpet cleaning in CR's test. The Calisto ranked "very good" this trip. Why? They Calisto they tested came with the electric SEB228 nozzle and not the SEB217 that the other Miele's with PNs tested with. Considering the price of the brand, why one standard power nozzle? That I don't know but I do know it makes a difference.

Personally Venson, the Prospero is ideal if you have a small kitchen, small baking needs. It replaces the Cuisine model (see below), a predecessor table mixer which was supposed to replace the much loved "Chefette," a hand mixer with a mechanically geared moving bowl and stand. We had a Cuisine and it was awful. Kept breaking down in its gear box and the mixing performance whilst good wasn't any better than chucking the mix into our old Kenwood food processor with the steel blade. In the end I had to buy another Kenwood Chef. Of course they are much bigger than the newer Prospero but at least you can get plenty of spares and you can custom build the old Chef to match your needs with attachments that are universal and cheaper to buy if you know where to look.
