I loved my Dyson but switched to Chinese robovacs because, even if stick vacs made cleaning the floor easy, I still sucked at consistency. Now I have three robot vacuums because…

Rubbish. All vacuums are plastic and Dysons actually use quite high quality plastic. When I worked there they were always really worried about Shark, because apparently they hav…

Yes. Meile vacuums are made out of quality plastic, and seem to survive bring dropped down the stairs better than my coccyx did. Due to the unfortunate quirk of language, its ha…

I like mine ok. It's lightweight and gets the job done well enough. Are there vacuums out there nowadays that aren't cheap plastic construction?

At the repair cafe I volunteer at. Dyson vacuums are the only items I've had to hand back without being able to open up fully to find the problem. I like our Dyson vacuum but no…

A vacuum is space devoid of matter. The word is derived from the Latin adjective vacuus meaning "vacant" or "void". An approximation to such vacuum is a region with a gaseous pressure much less than atmospheric pressure. Physicists often discuss ideal test results that would occur in a perfect vacuum, which they sometimes simply call "vacuum" or free space, and use the term partial vacuum to refer to an actual imperfect vacuum as one might have in a laboratory or in space. In engineering and applied physics on the other hand, vacuum refers to any space in which the pressure is considerably lower than atmospheric pressure. The Latin term in vacuo is used to describe an object that is surrounded by a vacuum. The process in which a mechanical device removes matter from a closed or open system in an effort to create a vacuum is called evacuation. Evacuated substances captured, removed from the flowstream in another location, and held under vacuum are sometimes said to be collected by the vacuum system. The mechanical force the atmosphere exerts on air and material obstructing the flow of air into a vacuum is referred to as suction. Read more on Wikipedia
