I use the set for many years, had only ordered new because the old one has disappeared when moving, high it was still okay. Why spread the dust in the apartment with a duster? The matching top on the Dyson and the dust is simply sucked away. I wipe for years no longer dust and with me it's spotless! ;-) The Flexidüse one comes also to smaller and more difficult places, virtually specifically in old radiators with fins. The nozzle have not quite airtight written on the connection between plastic and flexible part as some reviewers here, but the suction power is still sufficient. Dust, cobwebs, everything goes away.
