Who said it couldn't be done? - an $1,100 vacuum cleaner.
Sanyo Electric Co. Ltd. announced a cyclone vacuum cleaner with a function of cleaning air, SC-XD1, that removes dust from exhaust air by the filter mechanism composed of a plasma discharge unit and ultra low penetration air filter.
The number of particles that are larger than 0.3 mμ in diameter and exist in exhaust air, such as dust, can be reduced to 50 per liter, which the company described "as clean as high clean surgery room." The price of SC-XD1 is 131,250 yen (USD 1,065). It will be released Sept. 1, 2007.
