1. A medical waste collection system comprising:
a mobile rover comprising a waste container, and a pressure sensor configured to sense a vacuum level of a vacuum drawn on the waste container, and a rover controller in electronic communication with the pressure sensor and configured to receive from the pressure sensor a pressure signal indicative of the vacuum level; and
a chassis configured be removably coupled with the mobile rover to establish a suction path between the waste container and the chassis, the chassis comprising a vacuum regulator, and a chassis controller in electronic communication with the vacuum regulator, wherein the chassis controller is configured to be arranged in communication with the rover controller to receive the pressure signal from the rover controller, and further configured to control operation of the vacuum regulator on the chassis to regulate the vacuum level of the vacuum drawn on waste container based on the pressure signal from the pressure sensor on the mobile rover.
