The only 2-drum wash action.
Contrarotator
TM
Conventional washing machines may seem convenient,
but their poor performance lets you down. So James Dyson
asked his engineers to experiment with every imaginable way
of washing to design a better washing machine.
Along the way, Dyson engineers made a surprising discovery:
washing by hand gave better wash results than single drum
machines. Because the laundry is constantly on the move,
it is manipulated and flexed. This opens the fabric to the
detergent, releasing dirt quickly and effectively.
To replicate the movement of washing by hand, Dyson
engineers designed two aligned drums and engineered them
to rotate in opposite directions at the same time: laundry is
constantly on the move, manipulated and flexed.
Because the Contrarotator
TM
releases dirt more effectively,
it can wash laundry cleaner, faster and in larger loads.
