ABSTRACT:
A new and improved home-commercial floor covering vacuum cleaning and liquid cleaning apparatus employing a rotating beater disposed within a vacuum-liquid cleaning chamber. The beater vibrates the floor covering by striking the flooring surface to agitate the dirt which is then moved by a vacuum system into a removable collecting chamber. When the dirt laden air enters the liquid collecting chamber of the apparatus, the dirt impinges on the surface of the collecting liquid and is thereby deposited in the liquid while the dirt-free air is again moved through the blower. The blower exit provides a stream of air into the vacuum-liquid cleaning chamber to pick up additional dirt. A quantity of foam-type cleaning solution is available from a container for periodical release into the stream of air exiting the blower to provide foam on the floor surface adjacent the beater. The foam is picked up by the vacuum system adjacent the rotating beaters to remove surface soil and stains. The mixture of air, foam cleaning solution and dirt particles and stain materials is exhausted from the vacuum-liquid cleaning chamber into the liquid collecting chamber where the laden air is de-foamed and cleaned so that the air may be again recycled by the blower.
