ABSTRACT:
A vacuum cleaner is provided for use with an improved adaptor for associating auxiliary cleaning attachments with the cleaner. Insertion of the improved adaptor into an auxiliary suction port of the vacuum cleaner may be used to actuate various mechanisms internal to the vacuum cleaner. Such mechanisms include a pivoting lift bar situated on a lower side of the vacuum cleaner chassis, for lifting a main vacuum nozzle and rotating beater bar brush from a floor on which the vacuum cleaner is supported. Such lifting disengages the rotating beater bar brush from the floor while the vacuum cleaner performs auxiliary attachment cleaning. A pivoting diverter door may also, or in the alternative, be actuated upon insertion of the improved adaptor into the vacuum cleaner auxiliary suction port, for diverting suction power from a main suction nozzle through the adaptor and into an auxiliary cleaning attachment such as a hose associated with the adaptor. The improved adaptor includes various camming structures for performing such actuations preferably upon insertion and subsequent rotation of the improved adaptor in the auxiliary suction port. Engagement surfaces and guide elements of both the adaptor and vacuum cleaner facilitate axial rotation and securement of the adaptor in the auxiliary suction port.
