Abstract
A floor maintenance machine includes a clean fluid tank with a discharge funnel running therethrough that forms part of an exhaust pathway for a vacuum source. The vacuum source discharges an exhaust during operation of the machine from the exhaust outlet into the discharge funnel. The exhaust may be gaseous and/or include a liquid component in the case of a machine malfunction if liquid from a recovery chamber is non-ideally drawn into the vacuum source in the case a fail-safe does not work. The discharge funnel can provide a way for the liquid to exit the interior of the machine in such case.
