ABSTRACT:
The present invention relates to an upright vacuum cleaner having an improved assembly to optimize the assembly and operational characteristics of the vacuum cleaner. The floor engaging unit of the vacuum cleaner has a two-piece body including a base and a hood which are snap-fit together. A motor is rotatably mounted within the body at the end of a handle assembly. The handle assembly, which also functions as a conduit for dirty air to travel to a disposable filter bag, carries an electrical connector which connects the motor to power. The handle further provides a stop which engages a hose hook that slidably fits over the top of the handle, the stop being located such that the hose hook is properly positioned to support a hose during storage thereof. A filter bag, which is mounted to the handle at a location downwardly spaced from the top of the filter bag, is provided with a wire frame to help support the weight of the disposable filter bag. The motor is provided with a foot switch actuator assembly that allows actuation of the motor switch regardless of the radial position of the motor switch. A brush roller, which is rotatably driven by the motor, includes a pair of mounting end caps. The end caps include outwardly extending projections which are received by the base, releasably mounting the roller thereto. The invention reduces the time, labor and material required to manufacture and assemble an upright vacuum cleaner.
