Well this link will start many arguments!

@mylogic 

I have a three tiered approach. 

I  use four Roomba to automatically cleaning three times a week. They do a pretty good job of poking in between the cable lifters and under the beds. I have a cordless Dyson... great design absolutely crap construction of the cheapest thermoplastic in existence... but sucks. I have a central vacuum (with a multiple horsepower vacuum in the basement storage area, plumbed through the house) with connections in each room. This I use about once every month or two... it pulls out all the Roomba miss. 

I'm always amused that people that are unable to do something feel they have to criticize people that can. 

@ghdprentice You have nailed it. 
 

Your system(s) don’t suck!
 

l fancy a horse driven sucker like the one you have. I am ordering my basement straight away.

On a serious note, it is a never ending quest to keep all the stuff hi-fi wise clear of dust. It acts like a dust magnet. There have been many humorous debates about this already on Audiogon.

I have to agree with this article. The science and real data support it.

Those who can do, those who can't write bitchy articles or call it snake oil. OP which are you? 

Some responses have sorted a few.
