An improved floor cleaning machine of the type having a power source, propulsion means connected to said power source including detachable drive wheels for tracking on the floor surface to be cleaned, scrubber means for wetting and cleaning the floor surface, means including a wiper for drying the cleaned surface, and control means operatively associated with said propulsion means, scrubber means and drying means for controlling actuation of said machine, said machine having a normal operating position, wherein the improvement comprises:
- (a) said propulsion means being mounted on a removable carriage which is removably secured to said machine, said carriage being removable from said machine while the latter is in said normal operating position;
- (b) said machine having a frame, said carriage being removably secured to said machine frame;
- and
- (c) wherein said carriage is slidably supported on said frame.
In a self-propelled floor cleaning machine including means to apply cleaning fluids to floor surfaces in predetermined quantities, scrubbing means to forcibly bring said cleaning fluids into intimate contact with said floor surfaces, and means to remove said cleaning fluids from said floor after the same has been scrubbed, said machine including a chassis rotatably supporting a pair of drive wheels and a propulsion system carried by said chassis and adapted to power said drive wheels, said propulsion system including a drive motor and means to transmit power from said motor to said drive wheels, the improvement comprising a carriage assembly on which said propulsion system is mounted, said carriage assembly including a pair of spaced, outwardly extending flanges, said chassis including a pair of spaced, opposed flanges cooperable with said carriage assembly flanges to permit said carriage assembly flanges to be slidably received by said chassis flanges, and means for securing said carriage assembly in a predetermined position.
