If you thought automatic vacuum cleaners were only good for taking pets for a ride and head-butting walls over and over again, we have someone to introduce to you. His name is Mr Head, and he’s a retired iRobot vacuum fitted with bottles of brightly coloured paint. An artist in his own right, his drippy masterpieces are built up from thousands of splodges, and have even been likened to work by American abstract artist Jackson Pollock. Not bad, huh? To watch a video of Mr Head in action, head here.
