Abstract
An apparatus for cleaning a surface includes a body defining a cavity and terminating in a distal end that is adapted, in use, to be in the vicinity of a surface to be cleaned such that the surface forms an end wall of a chamber including the cavity; at least one cleaning liquid inlet for flow of a cleaning liquid into the chamber; a divider located in or at the end of the cavity that divides the chamber into first and second portions, the second portion, in use, being in fluid communication with the surface to be cleaned; and an acoustic transducer associated with the first portion to introduce acoustic energy into the chamber; wherein the divider is adapted to permit the passage of acoustic energy therethrough from the first portion to the second portion of the chamber to thereby allow pressure fluctuations to be generated at the surface.
