Intelligent suction function with deeper cleaning. With the iLoop sensor, the suction power automatically adjusts to the actual amount of dust. Thanks to intelligent noise optimization, the suction sounds are reduced to less than 71 dB(A). The smart battery management allows for a runtime of up to 50 minutes, thanks to a removable, rechargeable 2500 mAh lithium-ion battery. The universal LED display shows the entire operating status on a single screen, keeping everything in view.
