Abstract
This invention provides an improved method and system for controlling a self-propelled floor cleaning vehicle characterized by the fact that the vehicle has excellent cleaning performance. This method is applied to a floor cleaning vehicle that follows a guidance line located on the floor. It detects the level of dirt or scratching present on the floor and it controls the running speed of the floor cleaning vehicle corresponding to the amount of the dirt or scratching detected. It is thus able to modify the cleaning and polishing/buffing operation in response to the amount of dirt or scratching on the floor.
