Abstract
A mobile floor cleaning machine is provided, having a chassis on which running wheels are rotatably mounted, and having at least one cleaning unit which has at least one cleaning tool and is coupled to the chassis via a guide member. To improve the floor cleaning machine in such a way that the risk of damage to the floor cleaning machine or to an obstacle in the event of a frontal collision with the obstacle may be minimized, it is proposed that the guide member is elastically deformable in the longitudinal direction of the floor cleaning machine.
