Whether you’re cleaning carpet or hard floors, the innovative Siemens autoControl technology automatically adjusts the engine power to the type of floor you’re changing to. There’s no need to manually change the setting on the appliance, so you can vacuum without interruption. Behind this highly efficient system is the unique interaction of highPower motor, high performance nozzle, optimized seals and innovative PowerProtect dust bag. This high-performance technology from Siemens ensures first-class cleaning results with low energy consumption. The powerSecure system ensures long-lasting cleaning performance even when the bag is full. As a result, the new PowerProtect dust bag unfolds optimally and can absorb more dust thanks to the multi-layer high-tech filter material.
