Abstract:
A self-propelled vacuum-cleaning device for cleaning smooth and textile floor coverings, particularly in the private home sector. The device has a housing, a vacuum blower, an electrically driven cleaning roller, an electrical drive mechanism, control electronics, and a power source. The maximal electric power of the self-propelled vacuum-cleaning tool lies between 150 watts and 300 watts during cleaning operation, whereby between 120 watts and 220 watts are allocated to the vacuum blower, between 10 watts and 40 watts are allocated to the electrical roller drive for the cleaning roller, and between 5 watts and 40 watts are allocated to the drive mechanism, and whereby the control electronics have a power demand of less than 5% of the maximal electric power.
