Abstract
Abstract A fabric cleaning device having a container for cleaning solution, a movable tank for waste water and a cleaning head removably attached to the tank by a vacuum hose for cleaning the fabric requires external connections to a source of electricity and a source of pressurized water. A portion of the hose is formed rigidly to provide a handle. A vacuum pump mounted on a removable tank-sealing cover for creating a vacuum within the tank has an air outlet operatively connected to a spray gun by a detachable hose. A filter connected to the pump cleans air discharged through the outlet. The spray gun is mounted on the container and has a normally closed valve for selectively discharging cleaning fluid onto the fabric. Water directed through a hose and tank mounted coupling from the source to a discharge nozzle with a normally closed valve mounted in the cleaning head selectively rinses dirt and cleaning fluid from the fabric. The vacuum pump draws the resulting mixture of cleaning fluid, water and dirt from the fabric and conveys it through the cleaning head to the tank. The cleaning head tapers laterally to the upper end and tapers longitudinally toward the lower end. The vacuum hose is connected to the upper portion of the head adjacent the discharge nozzle. The lower portion of the head has a narrow lateral slit which provides communication between the fabric and the interior of the head for rinsing fluid and waste substances.
