This was an amazing purchase for me. The table saw and robotic dust collector work well independently, but apparently I had to turn them on manually. Of course, this isn't a difficult task, but I've often connected the dust tube to the saw only to turn the saw on later, and forgot to turn on the vacuum first. Or, if I got it right, I mostly just left the vacuum cleaner on while I prepared for the next cut, adjustment, encryption, etc. Extra noise and energy. This simple device has really helped
