Miele vacuum cleaners' exceptional filtration is based on a multi-stage system. It consists of the innovative Miele HyClean dustbag, motor protection filter and Miele exhaust filter. The interaction of these components ensures that more than 99.9% of fine dust1 is filtered. You can breathe with ease! It takes more than high wattage to make a good vacuum cleaner. With Miele, a number of design characteristics interact in a most efficient manner. The tight seal of Miele vacuum cleaners and perfect air flow ensure strong suction of the floorhead. Miele has developed especially efficient floorheads for low wattage vacuum cleaners; they achieve perfect cleaning results even with the lowest power setting. Quality is Miele's highest priority. From conception to finished appliance. Miele cylinder, mini upright and upright vacuum cleaners are developed and manufactured exclusively in company-owned factories. At the end of the manufacturing process, each individual vacuum cleaner is subject to comprehensive testing one more time. This care and attention results in exceptional quality and a long service life for Miele products.
