Miele has recently modernized and extended its production plant in Bielefeld (Germany): the newly created Innovation Centre for Professional Cleaning Systems plays a significant role to respond faster, more flexibly and with greater precision to customer wishes. Miele has invested just under 30 million euro since 2008 in the PRS (Professional Cleaning Systems) facilities at its second-largest and second-oldest production site. The most well-known products to originate from the factory, founded in 1916, are vacuum cleaners and dishwashers for domestic use. But a little known fact is that one third of expenditure on research and development is ploughed into commercial cleaning systems.
