Cleaning machine with a detachable cleaning module

A water extraction cleaning machine comprising:

• a foot housing having a suction nozzle conduit provided therein, the conduit terminating at one end at a suction nozzle opening;
• an elongated support member pivotally mounted to the foot housing, the support member being adapted for use in pushing and pulling the cleaning machine along a surface to be cleaned;
• and
• a portable cleaning module selectively mounted to one of the foot housing and the elongated support member, the cleaning module comprising:
• a module housing;
• a motor-driven fan supported in the module housing for generating a working air flow;
• a dirty water receptacle supported in the module housing for collecting dirt and dust, the dirty water receptacle being fluidly connected to the motor-driven fan and having an air/water separator member adapted to separate the working air from entrained water and dirt;
• a working air conduit provided in the housing and fluidly connected to the vacuum motor and the dirty water receptacle;
• an accessory hose having a proximal end mounted to the module housing and the distal end being adapted to receive a cleaning tool, the accessory hose being fluidly connected to the working air conduit;
• a clean solution receptacle supported in the module housing, the clean solution receptacle being adapted to store a cleaning fluid used in a water extraction cleaning process;
• a pump fluidly connected to the clean solution receptacle and adapted to draw the cleaning fluid therefrom;
• and
• a solution conduit fluidly connected to the pump and adapted to selectively discharge cleaning fluid therefrom onto a surface to be cleaned;
• wherein the portable cleaning module can be mounted to one of the foot housing and elongated support member for use as an upright water extraction cleaner, or the module can be removed from the foot housing and the support member for use as a portable water extraction cleaner in a variety of applications.
