The robot arm was set up in a glass booth in Stockholm Central Station where passersby could watch 1000 items of clothes being splattered with lingonberry jam, chocolate drink and tomato ketchup.
The robot was controlled via a Facebook page, which anyone living in Denmark, Finland, Norway or Sweden could log on to and direct the robot.
Individual users had a brief period to control the robot and aim it at clothing passing by on a runner. If they hit an item, it was washed and then delivered to them to prove the stain was removed.
The activity, created by Saatchi & Saatchi Stockholm, is part of a wider digital campaign running across Sweden, Denmark and Norway.
