ABSTRACT:
Imaging apparatus in accordance with the present invention generally include a housing and a portal defined therethrough, whereby a vacuum filter cartridge can be placed in an operable position within the housing by way of the portal. The vacuum filter cartridge can have a hose operatively connected thereto. Air can be induced to flow into and through the hose, and thereby into and through the vacuum filter cartridge. The airflow can have a velocity sufficient to cause debris to be inducted into the hose and into the vacuum filter cartridge to be filtered, thus rendering the vacuum filter cartridge and hose operable as a cleaning device.
