The invention relates an electrical cleaning and care appliance, pressure alarming method and apparatus for the appliance. Transducer elastic members of the appliance engage in resonance oscillation motion with bending strain characteristics, are symmetrically distributed on the left and right sides of the longitudinal axis (L2) of a drive shaft, and have approximately equal section moduli in bending, approximately equal lengths, approximately equal deflection amplitudes and opposite flexure directions； the angle between the longitudinal axis (L1) of a cleaning element and the normal direction of the transducer elastic member plane is 0° to 60°； the frequency of the alternating current in a drive coil is a fixed value equal to f0max−；n, where n is a fixed value in the range of −；0.3(f0max−；f0min) to 0.8(f0max−；f0min). Therefore, the appliance has a higher mechanical efficiency, a simple structure and a lower cost.
