摘要： A system comprises a first container (2) holding liquid (9) and a second container (4) holding a shaving unit (1) in the liquid (9). A pump (3) pumps the liquid (9) from the first container (2) into the second container (4). A drain (5) enables the liquid (9) to flow from the second container (4) back to the first container (2). A pump driver (6) supplies power to the pump (3) during active periods (Ta) of a cleaning cycle (Tt). A sensor (7) senses the power. A controller (8) detects a disruption in the flow of the liquid (9) by detecting that sensed information (Ab) deviates more than a threshold value (At) from nominal information (An). The nominal sensed information (An) occurs when there is no disruption in the flow of the liquid (9) through the pump (3) during the active periods (Ta).The threshold value (At) is in a range of 0.05 to 0.25 times a nominal value of the current (I) or a nominal value of the voltage (V) supplied to the pump (3) occurring when there is no disruption of the nominal flow of the liquid (9) through the pump (3) during the active periods (Ta).

摘要： The present disclosure relates to a cutting appliance (10), a blade set (20), and to a cutter (24) and a stationary blade (22) for said blade set (20). Said cutter (24) comprising a main portion (78), particularly a substantially flat main portion obtained from sheet metal material, at least one toothed leading edge (80) protruding from the main portion (78), the at least one toothed leading edge (80) comprising a plurality of teeth (82), and at least one scraping portion (300) comprising a tapered scraper profile (302, 304, 306) at least partially extending in a longitudinal direction (X) that is perpendicular to a cutting motion direction (126) of the cutter (24), wherein the at least one scraping portion (300) is, in a mounted state, arranged to contact a stationary blade (22) of the blade set (20) at a first wall (100) thereof to scrape off accumulated dirt and debris when the cutter (24) and the stationary blade (22) are moved with respect to each other when in operation. The disclosure further relates to corresponding manufacturing methods.
