A quick attach-detach assembly of a wet-dry vacuum cleaner of selectively mounting an air blower on a lid includes a blower housing supporting a motor and a fan mounted to the motor and a lid to which the housing can be removably secured. The lid includes an aperture, an annular wall encircling the aperture and an annular ringlike surface defined on the wall. A retaining wall portion extends over a section of the ringlike surface to define a tunnel-shaped section. The blower housing includes a face on which is defined a protrusion. When the blower housing is mounted on the lid, the protrusion of the housing face is located adjacent the tunnel-shaped section. A locking ring is mounted on the lid for limited rotation thereon. A rotation of the ring selectively locks and unlocks the blower housing from the lid.
