ABSTRACT:
A suction head for a suction cleaning appliance with means for delivering a cleaning liquid for application to a surface to be cleaned and collecting the delivered liquid from said surface having a liquid delivery duct disposed within an inner compartment itself arranged within a suction chamber. The duct is provided with fine holes whereby the liquid is delivered in a dropwise manner. The inner compartment and the suction chamber have smooth mouths arranged in a common plane so that the liquid delivered through the holes is constrained to contact the surface being cleaned before encountering air flow over that surface induced by suction in the suction chamber.
