ABSTRACT:
A wheeled vacuum cleaner is provided with an extension projecting upward from a base on which an electric motor powered suction producing device and a floor engaging nozzle are mounted. A handle unit mounted on the upper end of the extension is provided with an anchor that constitutes a strain relief about which a line cord for energizing the motor is looped. A hand operated safety trigger device controls energization of the motor. Pivotally connected to the base is a stand that is movable between a storage position and an active floor engaging position wherein the vacuum cleaner is supported by the stand. The stand is mounted and proportioned so as to be gravity operated automatically to the storage position where it is held by a releasable spring catch while the vacuum cleaner is being used.
