摘要： A compact, self-contained cleaner and liquid extraction unit having a body member wherein a handle half of the body has all of the electrical components sealed therein, and cleaning fluid is retained within a removable discharge head half of the body that defines a plenum chamber and carries a spray nozzle and vacuum intake head. Arrangements are provided for preventing cleaning solution from being discharged through the vacuum intake head or flowing into the vacuum blower for the unit, and in some embodiments, a single unit operates to create a vacuum in the plenum chamber and to pump cleaning fluid to the spray nozzle.

摘要： A compact, self-contained recycling extraction cleaner having a body member wherein a handle half of the body has all of the electrical components, except possibly the cleaning fluid pump, sealed therein, and the cleaning fluid is retained within a removable discharge head half of the body that defines a plenum chamber and carries a spray nozzle, filter and vacuum intake head, as well as, perhaps, the cleaning fluid pump. Furthermore, in accordance with another feature, solution conduits to and from the pump may be built into the wall of the body in a manner that, when the cleaning fluid pump is located in the handle half, the conduit portions of the two halves sealingly mate in the assembled condition of the body halves. Still further, arrangements are provided for preventing cleaning solution from being discharged through the vacuum intake head or flowing into the vacuum blower.
