The nozzle I bought for the small City because I was not satisfied with the Flatduese. We have just tiled floor. No wood or carpet. The Parquet is slightly wider than the flat and creates in spite of the small brushes (as you can see from the pictures, they are interrupted to allow bigger dirt) who procrastinate the larger Kruemel just before the die, to leave. The included adapter is not necessary for the telescopic tube of the DC26. Unfortunately, the nozzle has no device, such as the flat in order, together with nozzle insert the tube into the holder of the vacuum cleaner. So I had still attach a wall mount. The nozzle must be kept well to the joint. The construction works stable. Goods arrived packed quickly and well.
