The convenience of automatic tool-triggering.
Automatic tool triggering is typically an onboard sensor that recognizes when a
tool is turned on, and it initiates the dust extraction process without the need
to manually turn the machine on/off. This is particularly useful when the distance
between the vacuum and the tool is more than a few feet apart or when you are starting/stopping
the tool frequently. By eliminating the need to walk back and forth or to continually
bend up and down to turn the extractor on/off, you can focus on the task at hand
more efficiently, and reduce the noise associated with continuously running the
vacuum system.

With the flip of a switch, the trigger of your power tool, when plugged into the
dust extractor, gives you fast and easy dust removal at the source. No need to load
up wall outlets with cords or run back to your vacuum to turn it on and off. One
cord plugs into the wall, and your tool plugs into the extractor. No more bending
down or running back and forth to turn the vacuum on and off.
