FIELD: vacuum cleaning equipment. SUBSTANCE: vacuum cleaner has ejector whose passive nozzle is connected via pipelines with its hermetically sealed housing, coarse and fine filters positioned in housing neck portion, and closure with gasket adapted for closing neck portion of housing. Housing is further provided with intake and discharge hoses and water measuring pipe. During operation of vacuum cleaner, compressed air is supplied to ejector for evacuating air from hermetically sealed housing. Contaminations, including liquid, corrosive, fire and explosion hazard are collected by means of intake hose, when pressure difference (vacuum and atmospheric) is created. EFFECT: increased efficiency, wider operational capabilities and enhanced reliability in operation. 1 dwg
