ABSTRACT:
Cleaning apparatus for cleaning a generally planar generally horizontal surface comprises at least one nozzle for providing a jet of cleaning liquid directed against the surface and which is mounted by an arm on a shaft for rotation about the axis of the shaft which is perpendicular to the surface. The nozzle rotates within a chamber defined by a casing assembly which has an open lower end closed by the surface to the cleaning and which carries a seal for sealing against the surface to contain cleaning liquid within the chamber. The casing assembly defines a peripheral liquid collection region from which the liquid is withdrawn through an outlet by a pump. The nozzle is self-motivating and may be associated with an impellor having blades for inducing flow of ambient fluid, e.g. air, into the chamber, the air flowing out of the chamber with the cleaning liquid and assisting removal of cleaning liquid therefrom.
