<p>A floor scrubbing vehicle (12) having scrub brushes (34) mounted at the rear of the vehicle by a mechanism (48) which allows both the brushes and squeegee (38) to extend and retract transversely with respect to the vehicle. The mechanism is resilient, and allows the scrub brushes and squeegee to automatically retract inward upon contact with an immovable obstacle, and also causes automatic extension of the brushes and squeegee following passage of the obstacle. The scrub brushes and squeegee are mounted in a scrubbing pod frame (32) which can rotate about a vertical axis with respect to the vehicle to prevent damage, or to facilitate access for repair and maintenance. <IMAGE></p> |
