A wet/dry vacuum cleaner unit having a transparent tube on the exterior of its tank that serves as a sight gage to display the volume of water collected in the tank and as a drain hose for conveniently discharging water from the tank. A suspension system molded in the bottom wall of the tank allows the unit to be tipped on its wheels for draining purposes and allows the unit to readily trail the pull of a vacuum hose.
