The secret lies in how we optimize suction as a whole system. To avoid turbulence the air ducts are large and aerodynamically designed, the motor has soft mountings, together with sound absorbtion material and a two shell body design it is our most quiet vacuum cleaner. The machine is also equipped with efficient seals to minimize leakage, a low-noise floor nozzle and our patented, synthetic S-bag TM classic/long-performance.
