Abstract
A fabric cleaning apparatus and method uses ozone-bearing cleaning liquid which is spread over the fabric and then vacuumed up. The spreading and the vacuuming are both performed through a cleaning head or tool which has hoses to a vacuum cleaner and cleaning liquid tank. The cleaning liquid is ozonized by injecting air from a conventional ozone generator into the cleaning liquid tank or into the delivery hose. An air pump and/or a venturi in the cleaning liquid line are used for the air injection. The ozone in the air stream dissolves into the cleaning liquid, which both helps to clean the fabric and avoids excessive ozone concentrations in the air. The elements may be housed in a single movable unit.
