Vacuum cleaner
First Claim
1. A floor covering vacuuming and cleaning apparatus comprising:
- a housing defining a cavity with a transverse opening juxtapositioned to said floor covering, said cavity having inlet and outlet conduits connected thereto, said outlet conduit having a lower pressure than said inlet conduit,a rotatable generally cylindrical beating means mounted between opposite end wall portions of said housing, said beating means protruding from said opening for contacting said floor covering, said beating means includes a plurality of transverse alternate rows of arcuate finger like straps and broom-like wipers for striking the surface to be cleaned,a power means connected to said rotatable beating means for moving said beating means about a generally horizontal axis,a dirt collecting means partially filled with liquid, said collecting means having an inlet conduit connected to said housing outlet conduit and an outlet conduit connected to a low pressure suction of said pressure producing means, a higher pressure discharge of said pressure producing means connected to said housing inlet conduit,a cleaning solution holding means mounted in connectable contact with said housing inlet conduit for storing a cleaning solution to be foamed and used on said floor covering, directing said foam through said inlet conduit into said housing for removal of surface dirt, anda cleaning solution dispensing and foaming means fluidly connected to said cleaning solution holding means for discharging cleaning solution into said housing inlet conduit for foaming for discharge of foam upon said floor covering to be cleaned.

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.
