Abstract
A cleaning apparatus which is of a compact construction to facilitate easy manipulation and portability includes a housing enclosing a fluid pump and a vacuum fan and mounting upon opposite sides a recovery tank and a stowage panel. The stowage panel is adapted to stow the flexible wand having a nozzle when not in use. Also, the high voltage motor driving the vacuum pump is adapted to also act as half of a transformer in order to pick off the lower voltage needed for the low voltage motor driving the fluid pump.
