Okay, I know that these exsisted in my high-school tech room. I don't know if they were built by one of the teachers or bought. It was a shallow pit in the concrete floor that had a hose connected to the vacume system. It was finished with sheet metal. You swept up the floor into it and switched on the vacume. Worked great. |

Most dust collection systems have a floor level intake port for this exact purpose. Ill see if I can find a link. |

Crap. Beaten to the punch! Saw one somewhere too that incorporated the entire skirting (small gap under it) and an always on low volume vac- anything that got stirred up was drawn toward the skirting and removed. |

Barbers could use such a thing as an attachment to the base of the chair, hair clippings could be removed by simply sweeping them toward the center of the base. It could be the same vacuum as used for the hand vac most barbers use, or sold to replace it. |

[+] but an almost-as-good arrangement would just have a shallow "dust bucket" embedded in the floor. |

My parents had the manual version installed when we
renovated in 2005–2006. They go in the baseboards/toe-
kicks and have a kick-lever to open/close the valve and
signal the central vacuum sucker to suck. When I saw the
idea title, I was going to come here and say what I just said,
and that, therefore, this idea was unoriginal. That seems to
be what the previous annotators have done. However, I have
yet to see one that activates automatically using an optical
sensor. That would be cool. |
