Azizi, some (many?) English 'Hoover' a rug. They also have (or did?) have a kind of water heater called a geyser, which I think came from a product name. And Thomas Crapper is memorialized by 'crapper.'
I still say Xerox, but with my computer set-up, I am beginning to say 'scan.' Of course I remember when Kodak was widely used for any personal camera. 'Blueprint' is still used figuratively, but the computer put most draftsmen (draughtsmen?) out of work.
Will 'photograph' continue in use now that 'digitals' are replacing film cameras for much personal and news photography? (I recently found out that "Arizona Highways" and other mags with fine illustrations still request large film negatives for their scenic illustrations; the 35mm and 10+ mp 'digitals' do not produce good enough images for better photographic illustration).

Knickers seems to continue in use in England, although that item of clothing used in golfing and climbing sports in America has largely disappeared. Or are knickers still some peculiar kind of underwear that they have in England? Never did know what they were. Hmmm, what are long johns in England?
