摘要： Described is a nozzle (6) for a vacuum cleaner and a vacuum cleaner. The nozzle comprises at least one electrical terminal and an electrical circuit (10) configured to provide identity data about the nozzle via said at least one electrical terminal. Hereby it is enabled to via a wire line connection identify the nozzle in a unit such as the main unit (3) of a vacuum cleaner. This in turn enables correct control of the nozzle from the main unit since the main unit can gain access to important data about the nozzle and thereby provide an improved control of the nozzle.

摘要： A cleaning roller mountable to a cleaning robot is featured. The cleaning roller includes an elongate member extending along a longitudinal axis of the cleaning roller, and a vane extending outward from the elongate member. The vane includes a first vane portion attached to the elongate member, and a second vane portion attached to the first vane portion. The first vane portion extends from the elongate member at a location intersecting a radial axis of the cleaning roller. The first vane portion extends along a first axis angled relative to the radial axis and away from the radial axis in a tangential direction. The second vane portion extends along a second axis angled relative to the first axis. A first angle between the first axis and the radial axis is greater than a second angle between the second axis and the radial axis.

摘要： A cleaner head for a vacuum cleaner has a housing, an agitator mounted within the housing, and a drive mechanism for driving the agitator about a first axis A. The drive mechanism is mounted to the housing for rotation about a second axis R. The second axis R is offset from the first axis A. When the agitator is brought into contact with a surface to be cleaned, the surface exerts a reaction torque on the agitator that causes the drive mechanism to rotate about the second axis R.
