1. A vacuum cleaner comprising:
- a cleaner body having a suction cavity with an inlet port and an outlet port;
a cyclone module removably mounted in the suction cavity and having;
a separation chamber having inlet opening at a lower portion thereof and adapted to communicate with the inlet port and a cyclone outlet opening adapted to communicate with the outlet port;
an exhaust grill mounted in the separation chamber and in fluid communication with the cyclone outlet;
a ramp positioned adjacent the inlet opening and adapted to direct dirty air entering the inlet opening in an upward helical path along the separation chamber for separating dust or debris from air;
a debris outlet at an upper portion of the separation chamber;
a dust collection chamber adjacent the separation chamber and in communication with the debris outlet for collecting debris and dust separated from air in the separation chamber;
a vacuum fan/motor mounted in the cleaner body and having a suction inlet in communication with the inlet port and adapted to maintain a flow of dirty air from the inlet port through the cyclone separation chamber between the inlet opening and the cyclone outlet.
