We asked ourselves the same question. - But it is actually the case that, in addition to the small accessories "upholstery nozzle", "crevice nozzle" and "integrated suction brush" (can be "extended" on the handle), THREE floor nozzles are included: The standard floor nozzle (SBD 660-3), which can be switched between hard floor and carpet, the parquet brush (Twister XL SBB 400-3) and the turbo brush (STB 305-3). Most of our floor coverings are hard floor, so the parquet brush is the "always-on nozzle". This is very practical as it is about 40 cm wide! - And the turbo brush, which really lives up to its name, we store within easy reach in a drawer near the carpet. - (The standard floor nozzle is currently on holiday with us).
