All of Dyson’s vacuum cleaners operate at below 1,400W but the bestselling models in the UK use motors with half that power. James Dyson has claimed that Bosch are using in-built sensors in their line of vacuum cleaners to fool EU regulators into thinking they are more efficient than they actually are. Speaking to The Telegraph, Sir James claimed "Bosch has installed control electronics into some of its machines to wrongfully increase energy consumption when in use – to cheat the EU energy label. Their behaviour is akin to that seen in the Volkswagen scandal." Sensors built into the device allegedly instruct the motor to double its energy use when the vacuum's bag is full of dirt - unlikely in a test-bed. Bosch's response was swift and unequivocal. Dyson is taking legal action in Germany, Belgium and the Netherlands to challenge the energy efficiency ratings.
