ABSTRACT:
A vacuum system having a closed air flow loop for cleaning rugs and floor or other surfaces. There is a vacuum source having a suction side and a controlled air flow pressure side (exhaust side). A head assembly is adapted to ride on the rug or floor or other surface to be cleaned. At least one rotatable brush is positioned within the head assembly. The suction side of the vacuum source communicates with the head assembly to provide suction within the head assembly for picking up dirt or other materials. The air exhaust side of the vacuum source communicates with the head assembly. A turbine motor is positioned so that the air exhaust from the vacuum source impinges on and drives the turbine motor. The brush and the turbine motor are interconnected whereby the turbine motor drives the brush. The means interconnecting is at a right angle to the axis of rotation of the brush. Peripheral air containment means associated with said head assembly are present to prevent air from entering or leaving around the periphery of the head assembly when it rides on the surface to be cleaned. The device may also have a closed loop for cleaning liquid to continuously recirculate.
