The present invention is in the technical field of exterior cleaning and repair including maintenance and pertains more particularly to a system, apparatus and methods of housing, storing, organizing and transporting tools, equipment, materials, cleaning chemicals, and utilities for exterior cleaning and maintenance.
In the field of exterior cleaning maintenance, a variety of apparatuses, tools and utilities may be used. The most common utilities are water and electricity to run equipment such as vacuums blowers, chemical pumps and pressure washers. In most cases when performing exterior maintenance, it is necessary to move over considerable distance with long cords and hoses to connect apparatus and utilities.
Finding and connecting to utilities in the field can be a big challenge, and often utilities are just not available. Another problem with exterior cleaning and maintenance is that apparatus and accessories may be distributed from storage and scattered around a site, leaving an operator with a task of cleaning up and organizing. Yet another problem with exterior cleaning and maintenance is ability to reach into places in need of cleaning. Often ladders are necessary which can be very heavy, awkward and dangerous, making these chores nearly impossible especially for older and handicapped people.
