FIELD: acoustics; domestic articles or appliances.

SUBSTANCE: electroacoustic vacuum cleaner is intended for cleaning surfaces of objects from contamination, removal of litter and dust from carpet items, floor, walls and other surfaces, including rough and uneven surfaces. Electroacoustic vacuum cleaner comprises: housing with fan, air discharge device, pipelines, hoses to which detachable brushes, nozzles and other devices and appliances for cleaning, washing and suction of garbage and dust can be attached; dust collector, air cleaning device, electronic or simple vacuum cleaner control device. In order to more efficient cleaning, a vacuum generator is used in a vacuum cleaner with a generator power supply, an electric oscillation amplifier with an output power controller, one or more acoustic oscillation emitters located inside the device in contact with the cleaned surface. Acoustic emitters, one or more, are directed to the cleaned surface, facilitate removal of garbage and dust from the cleaned surface.

EFFECT: converters of electric oscillations into mechanical vibrations of brush, fabric and other material or device in contact with cleaned surface, facilitate cleaning of surface due to oscillations of material with high frequency on cleaned surface.
