The ADU-17X/X2 version is designed for a Hygienist working alone. The system's compressor, vacuum and handpiece is turned on with either the foot pedal or a power switch on the console (the power switch and foot pedal do the same thing). The handpiece can be turned off and on by reaching down and adjusting a toggle switch to the left of the black fan on the unit.
The ADU-17A/A2 was developed with customer feedback from the previous version and works best when a Dr is working with an assistant. The switch on the console turns on the compressor and vacuum. The foot pedal turns the handpiece on and off. This would allow an assistant to use suction continuously while a Dr is drilling (without needing to reach down and adjust a toggle switch).
