ABSTRACT:
There is disclosed herein an upright vacuum cleaner comprising a main body having a suction opening, and a handle body pivotally attached to the main body. A relatively simple cam, which may be made from sheet metal in the form of a box, is disposed in the main body and pivoted with respect thereto. The cam is engaged by a cam actuator of the handle body when the handle body is moved to its upright vertical position to cause the cam to pivot in a manner to raise the suction opening of the main body from the rug or carpet.
