Can a robotic vacumn cleaner like the Oku San No do a good job cleaning the house ?
How do you know if the whole room has been vacumned ?
How long should we charge it manully ?
If it gets stuck vavumming underneath a piece of furniture like a chair, what happens?
I’m doing a report on the History of computers, and I can’t find this answer straight forward. I know computers switched from Vacuum tubes to amplifying circuits, and some computers used like 18,000 vacuum tubes- In contrast with the amplifying circuits, does each computer just need one? or a couple? I mean was it all those thousand tubes to the one circuit that made it such an improvement? Or did it just need …less.. Like 100 circuits or something?
