ABSTRACT:
An improved movable control for a self-propelled upright vacuum cleaner. The control includes a sleeve longitudinally movably mounted on the distal end of the upright handle of the vacuum cleaner and includes locking structure for retaining the sleeve in a center neutral position, wherein the drive of the nozzle wheels is maintained in a neutral condition. The locking structure is readily manipulatible to release the sleeve from the neutral position when desired and permit it to be moved in opposite directions so as to effect corresponding forward or rearward operation of the drive. The sleeve is maintained relatively short while yet providing a long travel in providing facilitated user control of the drive operation. The sleeve is provided in two halves which are secured together by an improved securing arrangement. In one form, the locking structure is pivotable about an axis parallel to the handle end portion, and in another form, the locking means is pivotable about an axis transversely thereto.
