1. A vacuum cleaner, comprising:
a housing comprising a suction nozzle; a suction source fluidly connected to the suction nozzle for creating a working airstream through the housing; a cyclone separator for separating contaminants from the working airstream, the cyclone separator comprising an air inlet in fluid communication with the suction nozzle, at least one separation chamber, and an air outlet; and an exhaust grill mounted within the at least one separation chamber and fluidly upstream from the air outlet such that the working air stream passes through the exhaust grill before reaching the air outlet, the exhaust grill having a central axis and comprising:
a body having a side wall;a plurality of inlet openings in the side wall to provide fluid communication between the at least one separation chamber and the air outlet; anda plurality of airflow deflectors formed by closed portions of the side wall that are outwardly spaced in a radial direction, relative to the central axis, from the inlet openings.
