Methods and apparatus for attaching a pressure washing device to a storage tank that allows adjustment of the location of the pressure washing device. One embodiment includes a mounting plate adapted to be connected to a tank opening, a second plate hingably attached to the mounting plate, and a pressure washer attachment plate hingably connected to the second plate. The hinged connections may be arranged such as to allow rotation about two axes that are substantially perpendicular to each other. Linear connection apparatus may also be provided to control the relative location between the plates. A roof mounted system includes a vertical extension arm that is suspended from a roof-mounted manway. The vertical extension arm supports a primary pivot point about which a first extension arm deploys. The first extension arm carries a telescoping extension arm that has a secondary pivot point about which pivots a wash head arm having a wash head mounted on the end.

What is claimed is: 1. A system for cleaning an enclosed space comprising: a mounting plate connected to a wall around an opening into the enclosed space; an attachment plate hingably connected to said mounting plate; a washing device attached to said attachment plate and extending into the enclosed space; and a linear locator extending between an unhinged side of the mounting plate and an unhinged side of the attachment plate, wherein said linear locator controls the position of said unhinged side of said attachment plate relative to said unhinged side of said mounting plate, thereby controlling the position of the washing device in the enclosed space. 2. The system of claim 1 wherein said linear locator is manually controlled. 3. The system of claim 1 wherein said linear locator is controlled by a hydraulic or pneumatic cylinder. 4. The system of claim 1 wherein said washing device is adjustably positioned such that shadowed areas within the enclosed space are reached by cleaning fluid dispersed from the washing device. 5. The system of claim 1 wherein the system is transportable between two openings by a single person. 6. The system of claim 1 wherein said washing device comprises: a wash head operable to disperse washing fluid onto a cleaning area; an extension arm having a first end at which said wash head is attached; and a controller attached to a second end of said extension arm; and wherein the controller is operable to supply washing fluid and control signals to said wash head. 7. The system of claim 6 wherein said washing device is mounted such that said controller is outside the cleaning area and said wash head is inside the cleaning area.
