Abstract: An extraction cleaner includes a suction nozzle having an inlet path and suction fan configured to provide suction. The inlet path brings liquid and air into the extraction cleaner. Suction fan has a fan entrance, a recovery tank is spaced from the fan entrance. A separator element configured to allow liquid to flow into the recovery tank, inhibit the flow of liquid out of the recovery tank, and inhibit liquid from reaching the fan entrance, or all three. The separator element may be a butterfly valve configured to selectively close the fan entrance. The separator element may be a funnel extending into the recovery tank to block liquid from leaving the recovery tank during inversion. The separator element may be a fan separator adjacent the suction fan, which directs liquid outward, away from the fan separator, within the extraction cleaner, such that liquid is moved away from the suction fan.
