Well this link will start many arguments!

@willyht vacuum cleaning on a 1 to 10

l have discovered the efficiency of vacuum cleaners have severely diminished since all those cordless (no problem with what cable there) models have replaced the hard wired 1000W ones. More power in those olden days rewarded by better quality suckers.

Can anyone recommend a good cordless vacuum cleaner that does not loose suction after a few years? I am a self confessed fetishised fan for those long hose extensions. To get right in there with the spaghetti jungle of cables and hi-fi regalia appendages. 

Oh by the way, returning on track to the debate. I agree with the head/brain burn in syndrome. Sometimes, some people are just fooling themselves after an expensive upgrade, to justify the money that has been sucked out of their vaults.

New speakers--better bass. New amps--better bass. New preamp--better bass. New turntable--better bass. New cartridge--better bass. New speaker cables--better bass. New power cords--better bass. New power distributor--better bass. Better recording--better bass. New subwoofer? I'm hoping for better bass.

Not at all. 

@willyht  “better bass” The hobby of forever swimming up that river seeking better bass.

Are you talking about largemouth bass, or smallmouth bass?

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.
