Abstract
A waste collection unit for collecting waste material. First and second waste containers are supported on a portable cart. A control panel is configured to receive one or more inputs of selectively set vacuum levels in the first and/or second waste containers. A control system controls operation of vacuum regulators based on the input(s) to regulate levels of vacuums being drawn in each of the waste containers. Pressure sensors in communication with the control system may be positioned to monitor pressure in the waste containers. A back up port support on the portable cart may be provided to receive a vacuum line for coupling a vacuum manifold to a remote vacuum source not located on the portable cart. Container lamps may be coupled to the first and/or second waste containers and configured to illuminate the waste material within the waste containers to be viewed through transparent windows.
