  • a housing having a top, bottom and two side walls adapted to be removably disposed within said main body and operatively positioned between said inlet opening and said electric fan;

    primary filter means for trapping dust and objects of a predetermined size being operatively positioned within said housing;

    said primary filter means including a horizontal wall extending from one side wall to the other side wall and a vertical wall being spaced from said bottom wall of said housing and extending from said top wall to said horizontal wall to define a dust collection chamber adapted to be in communication with said inlet opening and a first path being positioned between said horizontal wall of said primary filter means, said two side walls and said bottom wall of said housing;

    secondary filter means for trapping dust and objects of a predetermined size being operatively positioned within said housing downstream of said primary filter means, said secondary filter means being spaced from said vertical wall to define a second path being in communication with said first path;

    said secondary filter means extending between said top, bottom and both side walls of said housing to form an air permeable end closure for said housing; and

    a movable lid being operatively positioned on an open front of said housing and being hinged about said top wall for forming a closure thereto, said lid including an opening adapted to be in communication with said inlet opening and said dust collection chamber and said lid being in engagement with said horizontal wall of said primary filter means and said bottom wall for closing the front of said dust collection chamber and said first path;

    wherein detaching said dust collector from said vacuum cleaner and moving said lid to an open position permits dust and objects to be discharged in a single tilting action from said dust collection chamber of said primary filter means and from said first and second paths being in communication with said secondary filter means.
