Sanyo Electric claims that its new vacuum cleaner can get the most stubborn
dust out of carpets—by sucking and blowing at the same time. Air that
would otherwise be forced from the cleaner’s exhaust is redirected to the brush,
where it dislodges dirt from carpet fibres. By blasting the dirt free before it
is sucked up, Sanyo says its new Jet Turn cleaner requires only 60 per cent of
the power of a conventional vacuum cleaner.
