Abstract
A water extraction cleaner comprises a system for delivering clean solution to a surface to be cleaned, a system for extracting dirty solution and air from such a surface, and a housing supporting the delivery system and the extraction system. The housing defines a recess for receiving a pair of tanks, an upright front surface of the recess being complementary to upright rear surfaces of the tanks. The housing is also provided with a pivot surface spaced from the upright surface of the recess and engageable by lower end portions, the pivot surface being formed and disposed to hold the upright surfaces of the tanks in snug engagement with the upright recess surface. Each of the tanks may be mounted on the housing by tilting the tank to insert the lower end portion thereof into the recess and then rotating the tank to an upright position about the pivot surface. The delivery system includes an inlet on the housing disposed to receive clean solution from one of the tanks when it is received in the recess in the upright position. The extraction system includes an outlet on the housing disposed to deliver dirty solution and air to the other of the tanks when it is received in the recess in the upright position. A detent arrangement is provided to removably secure the tanks on the housing in these operative positions, and the clean-solution tank includes a valve mechanism automatically actuated to permit flow from the tank when it is in its operative position.
