ABSTRACT:
An improvement of a combination motor and auxiliary cleaning mechanism actuator is included in a manually operated, rotary cleaning machine. The actuator includes an elongated actuator member mounted on the handle of the machine for movement among at least three actuator positions. The actuator member extends alongside the handle grip portion of the machine handle between two handle grips. Springs bias the actuator member to the first actuator position. Movement of the actuator member to the second actuator position places a first switch in an energizing state for energizing the motor of the machine, and movement of the actuator member to the third actuator position places a second switch in an energizing state for energizing an auxiliary cleaning mechanism of the machine.
