The airobrush is not part of Henry Hoover's standard kit but is available as a separate accessory. Inside this tool is a turbine which drives a brush roll that gives a beats as it sweeps action. This is particularly effective on carpets. An added bonus of this tool is that it doesn't clamp down onto carpets like the pedal tool can but instead glides over carpets easily. Its swivelling action also makes it more manoeuvrable around furniture than the pedal tool.
