An improved scrub head for a cleaning wand to be used with a floor cleaning machine. The scrub head is supplied with vacuumized air and pressurized cleaning solution through the wand from the machine. The scrub head has a nozzle for applying cleaning solution to the floor, a powered rotating tool such as a brush or a pad for scrubbing the floor, and a vacuum pickup shoe or squeegee for picking up soiled cleaning solution. The squeegee, when used, has flexible lips of a novel and improved design. The rotating tool is driven by an air turbine which takes in its air from essentially clean ambient atmosphere, and a valve selectively and automatically connects the vacuumized air to either the turbine outlet, thus causing the turbine and tool to rotate for scrubbing the floor, or to the pickup shoe or squeegee for picking up soiled cleaning solution and debris.
