The Multi II - the second generation of Multipurpose vacuum cleaners - offer a filter cleaning indicator on all models. This is a warning telling you that the vacuum is loosing performance and it is about time to clean or replace the filter. The Multi II also offers a Push&Clean function to clean the filter. This function is a semi-automatic method of cleaning the filter by creating an airwave hitting the filter from inside out. The combination of filter cleaning indicator and Push&Clean function makes this machine a truly unique offer. Together these features ensures a consistent high cleaning performance. The Multi II flagship model also offers Variable Suction Control that may come in handy when you need to reduce the suction power of the efficient 1400 W motor.
