ABSTRACT:
A cleaning apparatus includes a tank housing and a partition disposed in the tank housing so as to divide the interior thereof into pumping and cleaning chambers as the only chambers within the tank housing adapted to contain cleaning liquid. A submersible pump mounted inside the pumping chamber has an outlet connected to a first end of at least one tubular member, which defines a flow path extending from the first end and through an opening in the partition to an opposing second end inside the cleaning chamber and connected to a respiratory device for cleaning thereof. Cleaning liquid is pumped from the pumping chamber along the flow path, through the device for interior cleaning, and into the cleaning chamber to fill such chamber to an upper end portion of the partition defining an overflow weir, thereby immersing ad the device for exterior cleaning and allowing overflow into the pumping chamber.
