I don't know whether "halfbaked" includes "homebaked" [i.e. non-commercialised] in its meaning. If it does the following will be acceptable. If not it won't be.
It's a home-made but wholly successful non-allergy-causing vacuum cleaner system.
Fifteen years ago I bored a hole through the
floor of the broom-closet and put a meter of extension blow-end hose tightly-fitted through it into the under-floor crawl-space.
The vacuum cleaner has remained in the closet ever since with enough suction hose to reach everywhere. Bag-passing dust from the normally emptied bag stays under the floor where few ever venture.

Ever so toastily baked. Search for 'central vacuum'. Outlets in the walls, you plug a vacuum hose in and it automatically turns on the garage mounted machine. Even has a 'dust pan' for the kitchen, you kick a switch and sweep into the hole and it sucks it away, never to be seen again. |

The crawl space exhaust is an interesting idea, just be careful with what you run down it... |

central installed vaccums were a late 60's-early70's fad. my mother in law has one n her home and my husband wants one if we ever design a new one. |
|
| |
Yes, it was because I couldn't afford a central system, that I devised this no-cost one.

[a] I "had" the unit.
[b] I made up the long sucker from tubes found behind the local repair shop, and used the hose from the unit as the exhaust hose
[c] the hole in the floor oost me one jigsaw blade carelssly used
Total cost and care for 15 years zero
.
As a bonus, a long hose made from short sections makes easy the locating of blockages.
As a commercial item it's not only half baked; it's unbakeable. |

Ah, so desu. I misunderstood, I thought you thought you'd invented the central vac... |

One benefit to a central vacuum is that bag-passing dust and allergens are exhausted outside the house. Even if no-one occupies the broom closet in your house, there would be enough positive pressure to blow particles into other rooms. Making the broom closet air-tight would not be wise; this would defeat the vacuum's efficiency. One other thought: adding enough hose to reach every carpeted area of the house would increase air resistance and reduce the efficiency of the vacuum's motor-impeller. |

These are only Devil's Advocate annotations, however. If you have been happy with your vacuum for 15 years, that's more than I can say for myself. |

Two points : 1. There is no pressure on the broom-closet; a piece of hose takes the "clean" air from the dustbag THROUGH the hole in the floor. A telephone wireman I quizzed last year after being under the floor, said in pure Strine, "She's as clean as s whistle down there mate."
2, There is no discernible suction loss over 4M. I'm sure we have an expert among us who'll explain why. |
|
| |
I'm not an expert, but I play one on HB. |
|

The loss of pressure after 12 feet or so is VERTICAL feet. If you ran a hose up the side of the building and tried to suck water up it, it'd run out of power after a certain amount of time, no matter how powerful a pump you put on it, because the water is not pulled up the hose, but rather pushed by the outside air pressure into the lower air pressure inside. |
|
| |
But in a vacuum cleaner system, where you're not moving anything but air, it wouldn't make any real difference, as 14 pounds of air is a LOT of air, where 14 pounds of water is not much water. <Sea level air pressure being about 14psi.> Going along horizontally, it wouldn't make any difference at all to the pressure how long the hose was... |
