Abstract: Apparatus and method providing efficient cleaning of various surfaces. The apparatus including a collector and a controller. The collector having an inlet conduit, a vacuum pump, a first valve, a second valve, a tank, and a separator. The inlet conduit connects to an inlet aperture of the separator, the vacuum pump connects to an outlet aperture of the separator, the first valve regulates flow between a drain aperture of the separator and an inlet aperture of the tank, and the second valve regulates flow through a drain aperture of the tank. One or more filters may filter flow between the separator and the vacuum pump. The controller may be programmed to, upon sensing a full tank, selectively close the first valve and open the second valve and, after the passage of a selected period of time, selectively close the second valve and open the first valve. The collector and controller may provide an integrated, compact cleaning system that supports continuous operation.
