The invention comprises a cleaning apparatus having interchangeable cleaning solution supply reservoirs, a fluid pump, a vacuum fan, and a removable recovery tank, all cooperatively arranged in a housing of a unique compact design. The cleaning apparatus also includes a hose having separate hand tools which can be adapted for use on appropriate surfaces. Because different cleaning applications require a different cleaning solution to be supplied through the cleaning solution supply reservoir, each interchangeable cleaning solution bottle contains a cleaning solution appropriate for a particular cleaning application. The supply bottles can be quickly and easily changed so that the user may conveniently and efficiently switch between various cleaning applications. This process has the advantage that unused cleaning solution does not need to be disposed of or stored when switching to a cleaning application that requires a different cleaning solution.
