ABSTRACT:
A vacuum cleaning system is provided for a multiple level building. This system includes a conduit and raceway mounted inside of the building and arranged vertically to extend through a plurality of levels of the building. There is an inlet connected to the conduit at each level for communicably and releasably engaging one end of a first vacuum hose. The first vacuum hose has an intake nozzle attached at an opposite second end thereof. An outlet is disposed at a level of the building below the upper levels. The outlet communicably and releasably engages one end of a second vacuum hose. The second vacuum hose has an opposite end that is engaged with a vacuum apparatus, which apparatus is operated to create a suction that draws dirt and debris into the apparatus through the system. The raceway is provided adjacent to the conduit and accomodates a solution line in order to provide liquid for cleaning.
