Abstract
An upright vacuum cleaner includes a handle pivotally mounted to a base module, a lower portion of the handle mounts a lamp assembly which is hidden from view by the base module when the handle is in an upright, storage position and is visible above the base module when the handle is rotated to a use position. Between the front and back of the base module, a set of wheels or other projections that support the base module are mounted. The handle likewise has at a lower portion a set of wheels that mobilize the vacuum cleaner. In one embodiment, the pivot axis of the handle with respect to the base is selected so that rotation of the handle assembly from a use position to a storage position pivots a front end of the base module about the base wheels and thereby raises an agitation brush from contact with a surface to be cleaned. The rotation of the handle assembly with respect to the base module to its use position, moves the lamp assembly mounted therein from a hidden position behind a shroud in the base module to an exposed position above the base module for illuminating the surface to be cleaned immediately adjacent the front end of the base module.
