Abstract
A floor cleaning machine (100) utilizing a vacuum device (10) includes a tank (20) having an inlet (22) through which dirt, debris, or soiled solution is pulled along with air into the tank (20). The tank (20) further includes first and second air outlets (24, 30) both in communication with the tank (20). Air in the tank (20) is drawable out through the first air outlet (24) and selectively drawable out through the second air outlet (30). A check valve (40) is mounted in the second air outlet (30) preventing airflow from the second air outlet (30) to the tank (20). The check valve (40) allows the air in the tank (20) to be drawn out through the second air outlet (30) when more vacuum power is needed. The check valve (40) prevents airflow from the second air outlet (30) to the tank (20) when air is not being drawn out of the second air outlet (30) and while air in the tank (20) is being drawn out through the first air outlet (24) when less vacuum power is needed. A vacuum tool (104) in communication with the inlet (22) removes previously applied solution from the floor surface which is agitated by an agitator (112).
