The BlueEvolution concept is as simple as it is revolutionary: the innovative multifunctional appliance steams and vacuums in a single operation and not only saves the user over 93% of the previous water consumption, but also 60 per cent of the time previously required for cleaning. It is filled exclusively with clean water and works without chemicals. A special feature of the BlueEvolution is its blue light effect, which means germs don't stand a chance.
