A wet / dry type vacuum cleaner has a suction generator, a cleaner body including the suction generator at one side of a lower portion, an intake port being connected with a nozzle that is movable along a surface to be cleaned, and a discharge port through which a clean air is discharged, a contaminant separator removably mounted in the cleaner body to separate contaminant-laden wet air drawn through the intake port into the contaminant and water components and air, and then to store the separated contaminant and water therein, a cover, being open and closed, disposed on an upper portion of the cleaner body to seal an upper opening of the cleaner body, and a discharge path opening a fluid communication between the contaminant separator and the discharge port, for the air separated at the contaminant separating means to be discharged out through the discharge port of the cleaner body. Since the suction generator is provided at the lower portion of the cleaner body instead of the upper portion, the cover can be constructed in a simple manner and a user can remove the contaminant receptacle by simply opening the cover and emptying the contaminant receptacle.

A surface cleaning apparatus comprises an air flow passage extending from a dirty air inlet to a clean air outlet. A suction motor is positioned in the air flow path. At least one cyclone is positioned in the air flow passage. An associated dirt collection chamber is exterior to the cyclone.

Alternately, or in addition, a pre-motor filter having an enhanced surface area may be provided by configuring the pre-motor filter to extend outwardly of the pre-motor filter, such as by overlie part of the cyclone or the dirt collection chamber.

A fan motor apparatus of a vacuum cleaner having a diffuser unit is provided. The fan motor apparatus of a vacuum cleaner includes a fan motor unit into and from which an air stream is introduced and discharged in the same direction, and a diffuser unit having an air suction area to discharge an air stream to the fan motor unit through a fluid passage surface, the fluid passage surface through which an air stream is drawn in and discharged out of the diffuser. An air discharge area of the diffuser unit may receive the air stream discharged from the fan motor unit, and distribute and discharge the air stream through a perimeter of the air suction area of the fluid passage surface.
