Abstract
The water extraction machine according to the invention provides a quick connect system for mounting one end of a solution tube and vacuum hose to the water extraction machine housing and a simple and efficient means for conveying solution from the housing to a cleaning tool. One end of the vacuum hose and solution tube are received in a cuff member which is adapted to be received in the machine housing by a simple press fit interconnection. The cuff member provides a single connection for both the vacuum hose and the solution hose to the machine housing. The other end of the vacuum hose and solution tube are received in a clam shell grip tube handle which is in turn mounted to an extruded dual chamber wand. A first longitudinal chamber in the wand conveys vacuum through the wand and the second longitudinal channel conveys cleaning solution from the grip tube to the cleaning tool. The structure for the water extraction machine according to the invention results in a more efficient system for conveying cleaning solution and vacuum to and from the machine housing and cleaning tool. In addition, the system is adapted for quick assembly and disassembly by the user.
