Abstract

The invention relates to a suction nozzle (50), in particular for a hard-surface suction device (10), comprising a suction mouth (70) which is adjoined by a suction channel (60) to which a negative-pressure source (16) can be connected at its end facing away from the suction mouth in order to create a suction flow, wherein the suction channel has a bottom wall (82) and a top wall (83) which are connected to one another via side walls (84, 85). In order to develop the suction nozzle such that when it is connected to a negative-pressure source an effective suction flow is created in the region of the suction mouth while keeping the energy consumption of the negative-pressure source as low as possible, it is proposed according to the invention that the side walls are curved in the form of an arch. Also proposed is a hard-surface suction device comprising such a suction nozzle.
