An attachment for a vacuum cleaner 10 comprises a suction head 12 which includes a suction chamber 14 to create and contain a region of low pressure adjacent to a surface 16 to be cleaned. The suction head 12 includes a number of air bleeds 20 and these may be arranged as a first array first air bleeds 20a and a second row of second air bleeds 20b. Each air bleed 20 is arranged to induce cyclonic airflow as the atmospheric airflows into the suction chamber 14. This cyclonic airflow is directed towards the surface 16 to be cleaned and, in particular, an apex of this cyclonic airflow is arranged to coincide or penetrate the surface 16 to be cleaned. For example, the apex of the cyclonic airflow may locate within the carpet fibers of a carpet in order to disturb and disrupt dust and debris within the carpet. Accordingly, the cyclonic air bleeds 20 agitate the surface to be cleaned whilst also performing the function of a conventional air bleed within a suction head 12 of a vacuum cleaner 10.
