1. A vacuum cleaner comprising:
- a cleaner body;
a multi cyclonic chamber being in fluid communication with the cleaner body, the multi cyclonic chamber comprising;
a primary cyclone having a primary airflow inlet and a primary airflow outlet for separating contaminants from an airflow, andat least one secondary cyclone for separating contaminants in the airflow discharged from the primary cyclone;
a suction source having a suction source inlet and a suction source outlet, the suction source operative to generate and maintain the airflow flowing from the suction source inlet to the suction source outlet, the suction source being located in the cleaner body below the multi cyclonic chamber;
a main filter assembly including a main filter element having a selectively permeable material, the main filter assembly located in the cleaner body for filtering contaminants from the airflow that passes through the cyclonic chamber;
a discharge member having an opened upper end and a closed lower end, the opened upper end is coupled separably to a peripheral edge of the primary airflow outlet; and
a guide rib provided at the primary cyclone for guiding the airflow in a direction tangential to an inner peripheral wall surface of the primary cyclone, wherein the guide rib is inclined to one side of the primary airflow inlet according to a shape of the discharge member to prevent the air entering the primary air flow inlet from being directly introduced into the discharge member, wherein said airflow is further directed into said secondary cyclone which allows said airflow to enter said discharge member from the top of said discharge member.
