Self-propelled vacuum-cleaning device
First Claim
1. A self-propelled vacuum-cleaning device for cleaning smooth and textile floor coverings, comprising:
- a housing;
a vacuum blower in the housing;
a cleaning roller driven by an electrical drive, in the housing;
an electrical drive mechanism in the housing;
control electronics disposed within the housing,a power source connected to the vacuum blower, electrical drive of the roller, electrical drive mechanism and control electronics; and
a variable power control of the drive assigned to the vacuum blower or of the drive mechanism, said power control varying the power supplied as a function of a composition of the floor covering or of a degree of dirtiness,wherein a maximal electric power of the self-propelled vacuum-cleaning device lies between 150 watts and 300 watts during cleaning, wherein between 120 watts and 220 watts are allocated to the vacuum blower, between 10 watts and 40 watts are allocated to the electrical drive for the cleaning roller, and between 5 watts and 40 watts are allocated to the drive mechanism, and wherein the control electronics have a power demand of less than 5% of the maximal electric power.
