1. A cleaning apparatus for cleaning a surface in which cleaning solution is dispensed to the surface and substantially simultaneously extracted along with dirt on the surface in a continuous operation comprising:
- a) a housing;
b) a liquid distribution system operatively associated with said housing for distributing the cleaning solution to the surface;
c) a recovery tank removably mounted to said housing;
d) a suction nozzle secured to said housing and in fluid communication with said recovery tank, said suction nozzle including a front nozzle portion and a rear nozzle portion, said front nozzle portion being removably mounted to said rear nozzle portion; and
e) a suction source in fluid communication with said suction nozzle for generating suction to draw dirt and liquid through said suction nozzle and into said recovery tank;
f) wherein said front nozzle portion includes opposite side portions, said rear nozzle portion comprising opposite side portions having bottom edges, each of said side portions of said front nozzle portion having a projection that fits under a said bottom edge of a said side portion of said rear nozzle portion when said front nozzle portion is mounted to said rear nozzle portion, said projection being designed and constructed to prevent said front nozzle portion from pivoting on the bottom edge of said side portion of said rear nozzle portion upon removal of said front nozzle portion from said rear nozzle portion.
