Abstract (en)

[origin: EP0563788A1] A process for operating a wet-dry cleaner (1) having an automatic cut-out of the turbine (28) and an electric tool (18), which may be connected thereto, provides for an impermissibly high loading of dirt to be detected in the case of the loading of dirt of the filter (15) and/or of the dust bag (14) being exceeded or in the case of any other disturbance in the suction region, due to the fact that either the absolute pressure is recorded on the intake side of the fan wheel (16) of the turbine or a differential pressure is recorded in the region of a Venturi plate (21) on the entry side of the fan wheel. <IMAGE>
