ABSTRACT:
A hot water extraction system including a water tank having means for connection to a container containing a vacuum motor and to a water extractor and a hot water applicator, the applicator having a connection for attachment to a normal faucet, a hose from the faucet passing through a chemical cleaning solution, and a valve for the emission of a predetermined amount of the water including the solution, the vacuum created by the vacuum motor in the container creating a vacuum in the water tank and thereby providing suction through a hose leading to the water extractor whereby the hot water containing the solution which has been emitted on to a surface such as a rug by the applicator is drawn into the water tank where it is accumulated until the cleansing is completed. There are deflecting means in the water tank whereby the vacuum from the vacuum container draws air from the water tank in one direction while the entry of the water from the extractor is drawn into the tank from another direction so that the said water does not enter the line leading to the vacuum motor. The tank may be so arranged as to be carried on a conventional vacuum canister and is detachable and storable when the apparatus is not being used as a hot water extraction system.
