Whether you're cleaning carpets or hard floors, the innovative Siemens autoControl technology automatically adjusts the motor power to the type of flooring you're switching to. There's no need to manually change the settings on the device, allowing for uninterrupted vacuuming. Behind this highly efficient system is the unique interplay of a highPower motor, high-performance nozzle, optimized seals, and the innovative PowerProtect dust bag. This high-performance technology from Siemens ensures top-notch cleaning results with low energy consumption. The powerSecure system guarantees long-lasting cleaning performance, even as the bag fills up. This allows the new PowerProtect dust bag to unfold optimally and, thanks to its multi-layer high-tech filter material, to capture more dust.
