Abstract
A vacuum cleaning head for a vacuum cleaner includes structure for inducing vortices in the incoming air travelling between the sole plate and the surface to be cleaned. The vortices assist in entraining dust and dirt particles raised from the surface to be cleaned by a cleaning implement which may be a brush, beater bar or the like. The axis of the vortices is substantially parallel to the surface to be cleaned and the vortices b ring the rotating air substantially adjacent to and preferably in contact with the surface to be cleaned.
