Abstract: A cleaner head for a vacuum cleaning appliance includes an agitator assembly including a cylindrical body configured to rotate about its longitudinal axis; a main body defining an agitator chamber within which is supported the agitator assembly and a suction opening through which a portion of the agitator assembly engages a surface to be cleaned. The main body has opposing ends and a first exhaust channel in fluid communication with the agitator chamber. The main body is configured such that the cross-sectional area of the agitator chamber increases in a direction from one of the opposing ends of the agitator chamber towards the first exhaust channel.

Abstract: A docking station (190) is provided for allowing decontaminating parts of a floor care device (100). The floor care device (100) comprises at least one part (110) that is susceptible to contamination when the floor care device is used in a floor care mode. The method comprises detecting a transition of the floor care device (100) to a park mode, and in response thereto, executing a decontamination program, the decontamination program including emitting light with a wavelength of 222 nm and thereby illuminating the at least one part for the decontamination thereof.

Abstract: A method, and a floor care device (100, 200) are provided for allowing decontaminating parts of a floor care device. The floor care device comprises at least one part (110, 210) that is susceptible to contamination when the floor care device is used in a floor care mode. The method may comprise detecting a transition of the floor care device to a park mode, and in response thereto, executing a decontamination program, the decontamination program including emitting light with a wavelength of 222 nm and thereby illuminating the at least one part for the decontamination thereof.
