Abstract
A vacuum cleaner includes a housing and a nozzle in fluid communication with the housing. A suction source is held by the housing. The nozzle is in fluid communication with the suction source. A dust cup is selectively secured to the housing. The dust cup includes an inlet in fluid communication with the nozzle and a first inertial dust separation stage positioned downstream from the inlet. A first dust containing chamber is located adjacent the first inertial dust separation stage for holding the dust separated by the first inertial dust separation stage. A second inertial dust separation stage is located downstream from the first inertial dust separation stage. A second dust containing chamber is located adjacent the second inertial dust separation stage for holding dust separated by the second inertial dust separation stage. An outlet is located downstream from the second inertial dust separation stage. The dust cup can be selectively removed from the housing for emptying.
