Makita takes another step toward a truly cordless job site with Auto-Start Wireless System. AWS™ uses Bluetooth® technology for wireless power-on and power-off communication between the equipped tool and dust extractor. AWS™ is intelligent communication that eliminates cords and excessive noise since the dust extractor runs only when trigger-activated by an AWS™ tool. When the trigger is released, the dust extractor powers-down. The Makita AWS™ dust extractor (XCV08Z) is powered by two 18V LXT® batteries for maximum performance, and users benefit with an expanding AWS™ system that includes cordless tools for concrete, metal and woodworking.
