FIELD: mechanical engineering.
SUBSTANCE: suction inlet unit for vacuum cleaner having low pressure source is equipped with lower casing including first and second suction openings, upper casing connected to lower casing so as to define connection channel for first and second suction openings, and noise volume decreasing unit extending along connection channel which is in fluid communication with low pressure source.
EFFECT: increased efficiency in sucking of dust at both sides of vacuum cleaner.
