ABSTRACT:
A hand-held vacuum cleaner including a housing comprising mating first and second half housing elements. The housing has a handle and a nozzle. A motor is mounted within the housing for driving a shaft. A fan is mounted on the shaft for rotation therewith. A selectively separable bag assembly is mounted on the housing. A working channel is defined within the housing communicating the nozzle with the bag assembly. A connector joins a hose or similar attachment to the vacuum cleaner. The connector extends the flow path of the working air from the attachment to the nozzle. The connector comprises a first section for direct engagement with the attachment and a second section adapted for fitting over the housing in underlying registration with the nozzle. The second section includes a fluid flow channel and an edge wall surrounding the fluid flow channel and an edge wall surrounding the fluid flow channel and having an extent and configuration to fit in substantially fluid tight engagement with the nozzle. A pair of spaced apart hook-shaped projections extend outwardly from the edge wall. A releasable latch is movably connected to the edge wall on the side opposite the projections.
