房子有这个,我原以为它会不间断地一直吸,但昨天发现不是,还得我去打开开关,接
上吸尘器头部才能运作,这样有什么优势吗,比起普通的吸尘器?
另外,吸尘器头部要接电线,自己还带有开关,但我按不按开关它都一直吸啊,只要那
个大桶的开关还开着。

central vac is also called built-in vac, it is an integral part of the house.
The main benefits are
- it lasts a long time - average 20 years or longer
- it has very high suction power, 3-5 times higher than portable vacs
- it vents dirty air directly to the outside; portable vacs recycles the air
back to your room
- it is easy to use, all you need to do is to carry a hose around.
- it can be much quieter because you can put your central vac unit in the
garage, far away from where you use it
the metal ring on the hose connector connects the circuit and turns on the
vacuum. when you remove the hose, the circuit disconnects. The wire are
already built into the hose outlets.

谢谢回复,我最关心的是最后一段,我检查了墙上的出口,除了接管子的圆孔,还有一
个长方形的洞,里面看得到电线,但并没有接口,是不是没有安装而已?

the inlet I have has two metalic contacts, like this
the hose end only has a metallic ring, no cable or anything else.
http://builtinvacuum.com/parts/all/hoses/extension/extension-hose/
but apparently, there are different hoses/inlet designs, some of them
require additional wires/plugs, you can find some of the examples here, and
see which one is your type

不觉得这个吸力更大,和那种1500W的吸力类似,比手持的大些。好处就是安静,因为
电动机在地下室之类的地方。坏处是那个管子拖起来比电线累赘。

I have a different experience. the suction power is important and it feels
incredibly strong for my CV. That makes vacuuming a lot easier, I only run
one fast (very fast) pass of the floor, and it becomes spotless.
the suction power is quantified by several metrics. The most meaningful one
is airwatt. checkout this blog article
http://www.vacuumsguide.com/best-vacuum-suction-power/
and my old post here:
http://www.mitbbs.com/article/Living/32794377_0.html
as you can see from the table at the end of the blog article, the more
expensive portable vacuum, Miele Canister C3, consumes 1200W of electricity,
and can only generate 350 airwatt suction power. It also cost over $1000.
in comparison, the low-end central vac can already produce over 500 airwatt;
my 30+ years old Galaxie can generate over 1000 airwatt with only 1000W
power consumption. That is 3x times vacuuming power than the Miele.

In the last paragraph you made a mistake. "My 30+ years old Galaxie can
generate over 1000 airwatt with only 1000W", This is physically impossible,
since no system is 100% efficient. Central air system has long hoses and
pipes all over the house, there is a lot of energy loss in those pipes and
hoses. At lease the last two systems I used had those energy loss and made
them not superior.

,
you were right. I just looked it up, and my model is Galaxie GA 100, it has
675 airwatt, with a power consumption of 1500W (=2hp). The GA-240 model can
produce 1160 airwatt suction power, but not mine.
https://mycentralvacuum.com/product/ga-240-central-vacuum-power-unit/
it is not normal. properly installed vents should be all airtight (sealed at
all connectors). if you have loss of suction pressure, you either have
leaks along the pipes, or your power unit has a defective motor.
